  • RouterLess, house-wired network using multiple powerline adapters

    - by Cliff Arnell
    related to the 'old days' of one ethernet cable tapped with Ts for each monitor.... my question might be very simple... or not. I have an over-the-air internet provider with a wire dish with a powered transceiver and cat5 cable out of the providers supplied modem. I'm presently connecting the output of the modem into my wireless router which sends the internet signal all over the house. Standard stuff, I believe. My Question. Can I just connect the output of the modem into 1 powerline adapter and tie all my equipment such as computer, printer, laptop, Tivo recorder, etc. into 1-each local powerline adapters located near each devices resulting in a 'house-wired' network and no router? I'm bothered by the idea that my over-the-air provider might be using something in my router to establish and keep my IP connection alive. I did have to configure the router for my IP, a router which, in my proposed scenario, would no longer exist. Thank you for your help.

  • Laptop Randomly Turning On and Off

    - by Ian Mallett
    So, I have a pretty new laptop, and one of its quirks is that, at random times (though typically in the middle of the night), it seems to wake up from sleep mode, churn a bit, and then go back into sleep mode. I write "seems" because its fans are very loud, so it's obvious when it's not asleep, but during the time it is "on", I can't see anything on the screen. I have researched the problem somewhat, and could only find similar issues; nothing identical. In those cases, it appeared that certain devices could be responsible. Nothing is plugged into my computer during this behavior, but I nonetheless disabled every device's permission to wake the computer through the device manager. This included disabling the magic packet wake for the network (despite its only having a wireless connection). Using "powercfg /lastwake" gives an empty wake history. But, I also went through all the tasks and checked if they would wake the computer. None appeared to. The problem persisted, so, after some more research, I found this, and executed it for all power schemes on the computer. The problem persists. System: OS: Windows 7 Professional CPU: Intel 990X GPU: NVIDIA GeForce 580M/12GB RAM Motherboard: Clevo X7200 Model: NP7282-S1 (Sager-built laptop)

  • Router drops internet connection if I connect an additional pc

    - by BluePerry
    Hey, I'm using a SMC2804WBRP-G router connected to my ADSL-modem. Usually there are two computers connected to this router: a win7 ultimate desktop(wired) and a macbook air (wireless). Both working absolutely fine and never caused any connection drops as far as I know. A new room mate moved in last month and each time she starts up her win7 home laptop the router looses the internet connection. The laptop is on a wired connection. The first time she connected to my router, the connection dropped every 2 mins. To find out whats wrong with her machine I disabled all unnecessary services etc. besides the anti virus software. That helped to eliminate almost all of those periodic connection drops. But the start up drop remained and I've got the feeling that the router is still loosing connection from time to time. I haven't had the time to find out what service caused the periodic drops. But I'm more concerned about is that start up drop. Can anyone point me in the right direction to look for the problem? I would be very thankful for any hints or tips!

  • How do I access my samba drive through several layers of network topology?

    - by stephenmm
    I have a new windows 7 Home Premium machine that is in a different room than my main computer area. As such I have to use a bridge and another router. Everything is working wonderfully except I cannot access the SAMBA drive with the new machine. I know that SAMBA is accessible as an older WinXP machine can access it. A picture of my network would probably be helpfull: To ISP | | +---------------------------+ | WAN | | Cable Modem | | (2WIRE678) | | | | | +---------------------------+ | +---------------------------+ | | (|) (|) +-----------+ | Belkin Router | | | | Wireless | | (F5D) |--+ +--| WinXP | | | |SAMBA USER | | | +-----------+ +---------------------------+ | | | | +------------+ | | Ubuntu | | | Apache + | | |SAMBA Server| | +------------+ | | +---------------------------+ | | | Netgear Bridge | | (XET1001) | | | +---------------------------+ # # +---------------------------+ | | | Netgear Bridge | | (XET1001) | | | +---------------------------+ | +---------------------------+ | | | D-Link Router | | (DI-524) | | | | | +---------------------------+ | | | | +-----------+ | | | Win7 | |SAMBA USER?| +-----------+ More interesting data points: 1. I can ping the SAMBA server from the Win7 machine locally (Ie. 192.168.2.2) 2. I can access the webserver from the Win7 machine locally (Ie. 192.168.2.2) 3. I followed the advice to get Win7 and SAMBA to play nice: http://www.tannerwilliamson.com/2009/09/windows-7-seven-network-file-sharing-fix-samba-smb/ Sorry for being so long winded but it is kind of complex and I am really at a loss as to how to fix it. If any of you have some suggestions I would love to hear it!

  • How can I remotely display images on my computer?

    - by Jakob
    What I Have: A laptop booted with Ubuntu and a stationary computer dual-booted with Ubuntu and Vista, both connected through a wireless ad-hoc network. What I Want: I want a way to display images in fullscreen on my stationary, using my laptop as a "remote control". I want to be able to choose another picture at any time and have my stationary computer remain in fullscreen mode at all times. Preferably, I should also be able to display just an empty (black) screen. How can I arrange for this? What I Have Tried: I have tried simply SSH:ing into my stationary computer and opening the image files using an image viewer, but all of the ones that I have tried (Eye of Gnome, Mirage, Gwenview, and others) open a new window for every new image. I don't know how to force them into using a single instance. I have tried using the VLC remote control command line interface, but apart from seeming somewhat unreliable (exiting with segmentation faults at one point), it also displays some images with a green border and forces me to pause playback in order for the image to remain on screen. Bonus Question: In my final setup, I also need to play music through my stationary computer's speaker and have the ability to switch to another track at any point, like with the images. Preferably, I would like to control the images and the audio through the same interface. How can I best achieve this?

  • why Thinkpad T410s intermittent keyboard death?

    - by patrickmdnet
    I have a Thinkpad T410s running Windows 7 64-bit. I have had it for three months. It has the latest BIOS (1.41) and trackpad drivers. In the last week I have started to notice that the keyboard intermittently stops working. Specifically, keystrokes have no effect, including Fn-F12 (shutdown) and Ctrl-Alt-Del. The LED on the capslock key does not turn on or off. Whatever state the lighted keys (e.g. mute) were in remains. The trackpad and trackpoint work properly, and I can close apps and properly shut down the machine. When I attach a USB keyboard it is recognized, but no keys work. If I run the Lenovo keyboard test, all the keys register properly and the caps lock light works again. When I quit the test app, the caps lock light stops working. If I hit Fn-F12 while the keyboard test is running, it goes into hibernation. When the machine comes back from hibernation, once I exit the keyboard test I again cannot do any input on the keyboard. I'm pretty convinced there is a software or driver problem. I never saw this the first three months I had the laptop. I do not recall installing anything recently. I am sure I've received some Windows security updates. I tried using wired networking instead of wireless - no difference. There doesn't appear to be any inciting event; it usually happens when I am working over ssh. I switched from rxvt+ssh to Putty and the problem still occurs. Any ideas?

  • Best way to troubleshoot intermittent network outages?

    - by Ben Scheirman
    We have a Comcast 50/10 line into our office. We keep seeing very short but sometimes frequent drops in our internet service. It's enough to kick you off of skype and stop any websites from loading, which is obviously affecting our productivity. We've tried 4 different routers, we've tried moving everyone off of wireless and onto wired via a switch and so far nothing has helped. Right now we're on a Cisco SB WRP400-G1 router. Attached to the router is a 16 port switch going to the ports in all of the offices. We've moved to OpenDNS in the case that it was the comcast DNS servers going down. Today we tried putting the modem, router, and switch on a UPS to make sure it wasn't power fluctuations that was causing it. Every time we call Comcast, by the time they are here the internet is working fine. I'd like to somehow prove that the problem is with Comcast, so if that means plugging in a machine directly into their router and collecting data all day, I'm up for that. I just want to hear ideas on what tools to run and how to collect this data. I could just continuously ping google.com all day long but I'm not sure how valuable that data would be. Thoughts?

  • Possible Solution for Setting up a Linux VPN Server to Encrypt WLAN Traffic of Macs and iPhones on

    - by GorillaPatch
    I would like to set up a VPN server on debian linux to encrypt wireless traffic coming from my Mac or iOS device. I would like to use a certificate-based solution. Setting up a PKI infrastructure and managing certificates is OK for me. 1. Which server to pick? By looking through the internet and here on stackoverflow I found the following possible solutions: strongSwan IPSec and racoon Which solution is feasible for a linode running debian squeeze? 2. How to configure the network? If I understood correctly a VPN has a virtual network interface as an endpoint on the server side. Naively I would think that I need a DHCP server running on the server to assign a dynamic private IP (like of the class C network 192.168.xxx.xxx) to the connecting clients. Next I think I would need to set up masquerading to NAT the incoming VPN traffic to the real interface directly connected to the internet. Is this the right way to go? Do you have any configuration examples? I often saw VPN configurations used to connect to your home network, but that is not what I am looking for. I have a server up in the internet and want to use it as a proxy to encrypt traffic in insecure network environments like public WLANs.

  • How to connect computers to a network printer behind a router?

    - by kokbira
    General question: How to connect computers to an IP printer behind a router? Particular question: How to connect C-1 and C-2 to PRI? What? Where? [ISP] | | -> IPs:200.X.X.X/other configs:DC | [R-1] | | -> IPs:10.1.X.X locked by MAC,M:255.0.0.0,G:10.1.0.1 |¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯| | | [PRI] IP:10.1.7.7 [R-2] IP: 10.1.0.1,MAC:A | | -> IPs:192.168.1.X,M:255.255.255.0,G:192.168.1.1 |¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯| | | [C-1] IP:192.168.1.2 [C-2] IP:192.168.1.3,MAC:A Glossary and details: ------------------------------------------------------------------------------------ - IP: IP. - IPs: Some IP range. - M: Mask. - G: Gateway. - MAC:A: A MAC address that I will not inform you :) - DC: Don't care. - ISP: Internet Service Provider (not so much details about it on that case). - R-1: A real router or some concatenated so IP range bellow that block is 10.1.X.X and above is ISP. The provided IPs are provided by MAC. As all available addresses are in use, you must clone an existing one to join with a new device (and to disconnect the cloned one). - PRI: An network printer (some people here call that IP printer). - R-2: A TP-LINK TL-WR340G, mine wireless router (since my computer does not have ethernet input, it is my ethernet-wifi adapter :), admin access, MAC address cloned from C-2 (MAC:A). I've to configure 10.0.1.1 and 10.0.1.2 as DNS addresses, other wise I cannot connect C-1 and C-2 to Internet. - C-1: My computer, a CCE XLE-425 (remember: no ethernet input), with Windows 7, admin access. - C-2: another computer with better configs than mine, MAC:A, Windows XP. Requirements: I want to print, to access Internet and to do it myself (no need to call network admin men in black people). Pay attention to MAC clones and DNS info.

  • TCP dies on a Linux laptop

    - by Roman Cheplyaka
    Once in several days I have the following problem. My laptop (Debian GNU/Linux testing) suddenly becomes unable to work with TCP connections to the internet. The following things continue to work fine: UDP (DNS), ICMP (ping) — I get instant response TCP connections to other machines in the local network (e.g. I can ssh to a neighbour laptop) everything is ok for other machines in my LAN But when I try TCP connections from my laptop, they time out (no response to SYN packets). Here's a typical curl output: % curl -v google.com * About to connect() to google.com port 80 (#0) * Trying 173.194.39.105... * Connection timed out * Trying 173.194.39.110... * Connection timed out * Trying 173.194.39.97... * Connection timed out * Trying 173.194.39.102... * Timeout * Trying 173.194.39.98... * Timeout * Trying 173.194.39.96... * Timeout * Trying 173.194.39.103... * Timeout * Trying 173.194.39.99... * Timeout * Trying 173.194.39.101... * Timeout * Trying 173.194.39.104... * Timeout * Trying 173.194.39.100... * Timeout * Trying 2a00:1450:400d:803::1009... * Failed to connect to 2a00:1450:400d:803::1009: Network is unreachable * Success * couldn't connect to host * Closing connection #0 curl: (7) Failed to connect to 2a00:1450:400d:803::1009: Network is unreachable Restarting the connection and/or reloading the network card kernel module doesn't help. The only thing that helps is reboot. Clearly something is wrong with my system (everything else works fine), but I have no idea what exactly. I don't know how to reproduce this, but as I said, it happens every several days. My setup is a wireless router that is connected to the ISP via PPPoE. Any advice?

  • Does ICS modify windows firewall policies in the registry?

    - by insipid
    I had a host machine I wanted to enable ICS on. First I realized that doing so was not possible until I enabled the Windows Firewall. Once I enabled the firewall and set up ICS, I noticed due to group policy I could no longer disable the firewall. Also, any ports I tried to open seemed to be ignored. Although nothing seemed to be configured when I used the mmc snap-in to view local computer policy, when I checked the registry I noticed several policies set there in HKLM (such as disabling AllowLocalPolicyMerge). I was able to remove the policies from the registry and my open ports worked, but they were eventually re-added without my input. The network I am sharing the internet from is an "unsecured" wireless network with an authentication page, is it possible that this is causing those policies to be set? Did ICS set those policies? When you go to the properties of the ICS enabled adapter and go to the ICS settings it takes you to a tab called services where you can add and remove "services running on your network that internet users can access". Is this related to the windows firewall?

  • Why does my Belkin Play router regularly stop working for a few minutes at a time?

    - by YeahStu
    I recently purchased a Belking Play dual-band router for my home. About every few hours, the router stops working or "cuts out" for several minutes before coming back online automatically. My old one did this as well. I figured out a main problem was my wireless home phone, which sends a 2.4GHz signal. Anytime someone would call the phone, my router would get interrupted. Therefore, I unplugged this phone and got a wired phone. Unfortunately, my wired phone has the same problem. Therefore, I unplugged the wired phone. Unfortunately, my router still has regular issues. I live in a home with neighbors within close proximity to me, so it might be possible that their devices are the ones causing me problems. How can I determine what is causing my router problems? I thought that the point of a dual-band router was that if a signal was interfering on one band then it would be uninterrupted on another. However, it seems that is not the case. Does anyone have any tips on how to troubleshoot this or any knowledge you can share to properly set my expectations?

  • Snow Leopard takes a long time to connect to Windows/Samba server

    - by hood
    We run a very heterogeneous network here: There is some XP, Vista, 7, Leopard, Snow Leopard clients, and Windows 2003 (one remaining legacy app), 2008, and Linux servers. The main file server runs Ubuntu Linux and has been added to the Windows Domain and has been used for many years; SBS 2008 is the PDC (the 2003 and 2008 are on the domain also). In Leopard there were no problems at all authenticating to the file servers. We've upgraded one of the Leopard iMacs to Snow Leopard, though the same problem occurs in a new MBP which came with the newer OS as well as a clean install on another iMac. It does not matter whether connected through wired or wireless. In the Finder when clicking on the server - whether on first boot or after it is connected - it will display "Connecting..." for up to a few minutes before either generally working (if username/password in keychain) or displaying "Connection Failed" - at which time clicking "Connect As" and typing in the username/password will take some more time and eventually work. Sometimes it will display "Connecting..." indefinitely. (I've left it as long as 15 minutes before trying something else) Accessing shares on the the 2003 and SBS servers have the problem (so I don't think it's a Samba server issue). The Server 2008 Standard is connecting instantly at the moment. Accessing the share through an alias/stacks doesn't have this problem. Leopard and Windows clients still have no problem. I've searched Google but hasn't yielded any working result. How do I get rid of this delay?

  • Can't access random web pages on my MacBook Pro 2012?

    - by Faruk Sahin
    Sometimes I can't access random web pages. The page simply doesn't load. If I wait for around a minute doing nothing, it will load. It happens very random and very intermittent. Sometimes it starts when I try to access youtube.com or cnn.com. When it starts, it happens once in a minute or once in 5 minutes for random web pages. But if I am downloading something, the download continues without any interruption. And also I am able to ping the address I can't browse. Then if I wait for around a minute, everything starts to work fine at the browser side also. I have tried a lot of different browsers. I have tried changing my DNS servers to Google's public DNS servers. Using a cable instead of the wireless connection doesn't work either. No one else in the network has this problem, but me. What can be the problem?

I am trying to download and install Aircrack-ng. So used the command sudo apt-get install aircrack-ng. But the installation stops with the following error : update-initramfs: deferring update (trigger activated) cp: cannot stat `/vmlinuz': No such file or directory dpkg: error processing bcmwl-kernel-source (--configure): subprocess installed post-installation script returned error exit status 1 Errors were encountered while processing: initramfs-tools bcmwl-kernel-source E: Sub-process /usr/bin/dpkg returned an error code (1) I don't even have the aptitude command installed till now. Are all these errors because of I am running the ubuntu from USB drive? Is there any simple and easy way to go to Ubuntu Software Center and download all the required essentials at one shot and then Aircrack-ng? I could not find the Aircrack-ng in Ubuntu Software Center Can anybody give me detail steps to solve all my problems above. I am frustrated searching for updates and installations. When something works and something does not work. Can anybody suggest me how I should proceed after installing ubuntu to run on a USB drive. So that I can use the OS like Windows.

  • Using Different Networks with Different Proxy Servers on Windows 7

    - by John
    Hi, I have a laptop running Windows 7 Professional. There are two wireless networks I connect to every day: Home: no proxy server Work: proxy server with authentication On my iPad and iPhone, I've got two WiFi network profiles (one for home, one for work). The work one has the proxy server settings specified. The home one has no proxy specified. It all works great and I don't need to go changing settings around whenever I move from home to work or vice versa. On my laptop, however, I can't seem to get this going. I can certainly connect to both networks, but when I'm at work I have to go and change the proxy settings (in Internet Options) to be able to use the network. When I'm at home, I have to then go and turn them off. It's a small thing, but considering this is something I have to do every day, it's a bit annoying. Is there any way I can make Windows automatically switch proxy settings on or off based on the network I'm connected to? Thanks, John

  • What was your biggest waste of money, and what should you have bought instead? [closed]

    - by rob
    I waste a lot of money on computer equipment and other electronics that I don't really need. I've also bought software that I've never really used, or which as been replaced by better free software. As I'm buying things, it doesn't seem like much--fifty bucks here, a hundred dollars there. But when I go back and look at how much I've spent over my past few electronics purchases, I usually start to think of the other things I could have bought with that money instead. Most of the computer hardware and electronics don't usually improve my life by much, if at all. Case in point: back when I was in college, I prided myself on getting the best deals for computer hardware, but when I went back and added up all the money I had spent, I had probably wasted close to a thousand dollars on "cheap" $100 hard drives that eventually all went bad (including the warranty replacements). Even if they did still work, it would not be worth the effort to use them, because they're too small and too noisy by today's standards. I've also spent thousands more on other junk, such as RAM and CPU upgrades that only gave modest performance jumps, and wireless audio transmitters that I used for a short time to stream music from the now-defunct Yahoo! Music service. Every time I see a really great deal on RAM or video cards, I come one click away from buying them, but these days I'm usually able to resist. I've been wanting to get into woodworking ever since I moved into my house, and five years later I'm finally saving up for a $600 table saw. Sure, I've already got a toolbox and a couple of the essential power tools like a drill and a jigsaw, but I can't help but think that I'd have an entire shop full of woodworking tools and a lot of nice wood furniture if I hadn't wasted all that money back in college. What has been your biggest waste of money on computer stuff and technology? If you had all that money back, would you make the same mistake again and buy the same types of things, or would you spend it on something else?

  • Freshly installed dd-wrt on dir-300 and no internet. What to do?

    - by Erik B
    With the d-link firmware I just connected the router and it worked, as is expected when using DHCP, but with dd-wrt I have no internet access. It is configured with DHCP, and dd-wrt's wan status page reports that it is connected and that it has an ip address. Yet it is impossible to reach the internet. If I disconnect the router and plugs the cable directly into my computer I get internet access, so it's obviously the dd-wrt software that isn't doing its job. However, I have no previous experience with the dd-wrt software and have no clue what to look for. I thought it would just work. By the way, the power led is orange, the internet led is off, and wireless+lan1 is green. They all used to be green with the d-link firmware. Not sure if it's relevant, but now you know. Does anyone have any idea what I should do to get internet access (besides reinstalling d-link's firmware)? EDIT: It's a version B1. I read that it is very different from the A1 version, so I thought it may be relevant.

  • VirtualBox with Ubuntu Server guest can't ping outside

    - by Danidan
    Here's my situation: an Ubuntu 12.04 Host running VirtualBox; two guest VMs running Ubuntu Server 12.04 home network, so my Host pc has a wireless connection to the router of my ISP. My problem is in one of the virtual machines: it has 3 NICs, one in NAT mode and the others in Host Only mode. My purpose is to use eth0 (NAT) for Internet access and eth1, eth2 (Host Only) for management of internal virtual network (eth1 uses a VBoxNet with this IP 192.168.69.254). Whenever I try to $ping 8.8.8.8 I get Destination Host Unreachable. While if I $ping 192.168.69.10, that is the IP of the other VM, it works. I can't also ping my Host nor my router My /etc/network/interfaces file is: auto lo iface lo inet loopback auto eth0 iface eth0 inet dhcp auto eth1 iface eth1 inet static address 192.168.69.1 netmask 255.255.255.0 auto eth2 iface ifconfig $IFACE 0.0.0.0 up up ip link set $IFACE promisc on down ip link set $IFASE promisc off down ifconfig $IFACE down $route -n returns: Destination Gateway Genmask Flags Metric Ref Use Iface 0.0.0.0 10.0.2.2 0.0.0.0 UG 100 0 0 eth0 10.0.2.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 192.168.69.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1 192.168.100.0 0.0.0.0 255.255.255.0 U 0 0 0 virbr0 Forgetting for now what eth2 needs to do and its setup, why I can't go outside the Host box? What can I do to help you helping me? :-)

  • Ubuntu network card problem.

    - by Steve Greene
    Hello folks, Several days ago, I installed Ubuntu 9.10 onto my Acer Aspire 3100 laptop, running it alongside Widows Vista as a dual-bootable system. Creation of the Ubuntu boot CD went fine, and the installation onto my hard drive was flawless. Ubuntu opens and behaves as I would expect, except for one little problem. For reasons unknown to me, Ubuntu is not communicating with my laptop's networking hardware, and I have no internet connectivity, it works fine under Windows Vista. Up in the right side of the Ubuntu desktop, I click on the network icon and it does not show a wireless connection at all. At home, where I use a dialup modem, I also see no means of getting online. My modem is an HDAUDIO Soft Data Fax Modem with Smart CP,manufactured by CXT (Conexant Systems Inc., file version 4.0.13.0, and the driver version is 7.58.0.0). I am an advanced computer user, but I am not a programmer. I seek a solution that is user-friendly for normal people, something equivalent to a driver that I can easily install or activate that will allow Ubuntu to see my hardware and get me connected. Can anyone help me over this hopefully-little glitch My processor is a Mobile AMD Sempron Processor 3500+ at 1.80 GHz, 1.50 GB RAM, and a 32-bit Operating System.

  • Printing special / extended characters on web page - Firefox or printer issue?

    - by edmicman
    My dad brought this to my attention and I'm looking into it, but thought I'd post here and see if anyone has any ideas... He's running Win7, using Firefox and printing to a wireless connected Brother HL-2170W printer. He's got a web page (http://cornandsoybeandigest.com/inputs/fertilizer/applying-nitrogen-after-planting-0512/index.html) that has extended/special characters in it - the funny "a" in Fernandez. The characters show correctly in Firefox on the page. He printed it, and the extended "a" printed as a diamond with a question mark. He says it shows that way in the print preview, too. I pulled up the same page in Ubuntu, Firefox, and it displayed in my print preview and physically printed everything correctly. I just checked on my wife's Win7 PC in Firefox and the print preview looked correct on her system, too. We have a Brother 2040 here. Soooo, my question is, is this possibly a problem in the browser somehow, or the printer driver? I'm leaning towards the printer driver now, but I can't say I've run into this before. Is it a setting somewhere? I just installed this printer for him the other day, using the CD that came with it; I could try updating the driver from Brother's website I guess. Is there anything else I should look at or check? Thanks!

  • Power Outage Interrupted Upgrade from Windows Vista Ultimate to 7 Ultimate, Reverted to Vista, Now Vista is failing... What Next?

    - by tednewk
    I was in the midst of what seemed to be a successful upgrade from Vista Ultimate to 7 Ultimate when there was a brief blackout. The upgrade failed and Windows reverted back to Vista. Now Vista is very slow to boot, has problems waking back-up from inactivity and quickly loses it's wireless connection. The wake-up problem manifests itself as the mouse is clearly shown on a black screen but I have no access to the Desktop or Taskbar or Explorer. Even Alt-Ctrl-Delete doesn't seem to work. No task menu, no reboot. Hitting the reset button reboots the machine with the usual Black Screen warnings offering Safe Mode. I tried to do a system restore to a point before the upgrade. That didn't seem to work. My guess is that my system is a mutant with parts of Vista and parts of 7 crashing each other. I would like avoid a clean install if at all possible to avoid reinstalling other software. What should I try now? My thoughts are: My a system back-up to lock the computer in place Trying a second 7 upgrade If that appears to be working make another back-up If not reload back-up and try a repairing Vista from DVD. If that appears to work make another back-up, let system stablize about a week then try 7 install again If that doesn't work are there any other options to try before settling for a clean install? Another complication, I am doing this by "remote control". I'm traveling with my job and I'll be talking my son through it over the phone. (Kind of like the landing the 747 cliche from all the 70's adventure shows!) So is there a way of simplifying the steps? Thanks Ted

  • Uninstalled server 2008 now router won't handle DHCP

    - by john
    My set up is this. server behind router, router has a server and switch connected to it with multiple computers. router used to serve DHCP and DNS, a couple of days ago installed AD, DNS and DHCP on the server, and the server gave out IP's. For various reasons we had to uninstall the domain on our server. I removed AD, DHCP and DNS from the roles and set the router back to serving DHCP and DNS. Now I can't get computers on the network. I reset my router back to factory defaults, and if I plug a computer directly into the router I can get a IP address, but all the computers behind the switch can't get an IP address and can't see the router. All my computers say unidentified network, and if I ping the router it says host is unreachable. On the other hand, my wireless devices are just fine and connect no problem. But for desktops, ipconfig /release doesn't release anything and /renew can't find a server to renew on. My router log shows several FIN scans but they are from innocuous websites (google, netgear) and it shows a couple of smurf attacks but they are all from my external IP. Any ideas? the server isn't even connected to the route right now, and all the computers are set for dynamic IP addresses.. I don't know what else to try? Any help?
