• Not working WEP key in Ubuntu

  - by stupid-idiot

  This time I've got some problem with connection to the internet from my old laptop with ubuntu, I already had some problems with setting up the radio on my network card but I think it works now since it finds some wireless networks. The problem is that I can't connect to my router via wi-fi even if I'm hundred-percently sure the wepkey I punch there is correct, it works via LAN though. Also, I'm not able to ping myself with 127.0.0.1. I'm sorry to say it but I don't think I can stand this shitness for much longer. Although it's much much faster than Windows it's useless since i can't download any libraries for development. If anyone has any experience with this, even indirect, please leave your answer or comment thx

• Using multiple wifi connections simultaneously on Windows

  - by Salman A

  My office PC has a one wireless network card and there are three available wifi connections: primary, backup and backup of a backup (grin). Is it possible for me to use all three simultaneously. If this results in an increase in bandwidth that's well and good, but primary reason is every now and then one of the network fails and i have to switch back and forth between the available networks by disconnecting, viewing available networks and connecting to next one hoping its running. Do i need more than one network card or a software e.g. a proxy.

• Nokia Pc Suite problems with bluetooth (win7)

  - by wurlog

  I have a new Nokia C5-00 and a HP 620. The Bluetoothdriver are installed and the windows Bluetoothstack finds the mobile. After installing Nokia PC Suite I am asked to choose a connection method. As I click on Bluetooth the Nokia PC Suite shows an error message: "Cannot use the connection type.Check that all the needd hardware,software and drivers are available. (Code: OpenMedia)" I tried to switch it on and off via the "wireless" key on the laptop. The HP Software for the button shows that the Bluetooth is deactivated and advices me to go to the device manager and activate the Bluetooth device. Strangely the Bluetooth symbol (I guess from the windows Bluetoothstack) pops up at the same time and I can use the Bluetooth in it's basic windows features, but still nokia suite won't work. ideas????

• How to reset video/display drivers in Vista without restarting OS?

  - by jdk

  Currently I have to reboot my system if an external monitor is hooked up for it to be correctly detected and used. I think it would be faster to restart/reset the video or display drivers instead. How do I do this under Vista? I seem to remember from an old laptop using a Windows command-line command that would restart the wireless networking card device when it crashed. Is there something like that for video drivers? Background/Reason Because people rightfully ask why? - This is part of a larger problem which I'm waiting for resolution on from the manufacturer. In the meantime I'm looking for the above quick fix. Actually my video card often crashes my laptop when attaching an external monitor and trying to detect or use it. No solution from vendor yet and latest drivers do the same irksome behaviour. Windows says: A problem with your video hardware caused Windows to stop working correctly.

• What is Light Peak

  - by Jonathan.

  I've heard this a lot recently, todo with Apple and Intel. Some says it's a protocol, others say it's fibre optic, and others say it's copper. One source even said it was a "wireless wire". Apparently it can carry data, but not video streams, surely the cable can't know the difference between 1s and 0s representing data, and 1s and 0s representing video streams. Or it will replace all the wires we currently have except power, another place said it is for inside laptops. Those are just examples so I haven't given any sources, I just want to know what on Earth Light Peak is?

• Windows IIS test server setup

  - by chopps

  hello everyone, I picked up a new server to do some testing and need of a little help in setting up my environment at home. Here is what I would like to do: The test server will be used to test new code and configurations for a SaaS product. I would like from my laptop to enter www.acme.com and have it hit the server. The server is connected to a wireless router. I have windows server 2008 with IIS running on an an IP of 192.168.1.4. What is the best way to set this up? I want to hit the test server for www.acme.com and not go out to the internet. Do i need to mess with the LMHosts file? Thanks for the help. Im sure its easy but have never done this before.

• netsh wlan add profile not imported passphrase

  - by sirlancelot

  I exported a wireless network connection profile from a Windows 7 machine correctly connected to a WiFi network with a WPA-TKIP passphrase. The exported xml file shows the correct settings and a keyMaterial node which I can only guess is the encrypted passphrase. When I take the xml to another Windows 7 computer and import it using netsh wlan add profile filename="WiFi.xml", it correctly adds the profile's SSID and encryption type, but a balloon pops up saying that I need to enter the passphrase. Is there a way to import the passphrase along with all other settings?

• Windows 7 - sharing file - slow seek time?

  - by progtick

  I do not want to copy the files. I simply have video files (.flv) on one computer and I would like another computer user to watch them without copying. Playback is fine, but seek time (as in if you move the cursor to skip some portion of the video) takes forever! I thought wireless speed might be the culprit, so I wired the two computer. Maybe I saw some improvement but still so bad. It's 1 Gbps! (I know real speed will vary, but before I monitor real speed and such, do I have reasonable issue? Or am I bound to have very slow seek time?) What is going on? I must mention some of these files are huge!

• Stream music from Laptop to iPod Touch over Wi-Fi

  - by codeulike

  Rather than running a long cable from my Laptop to my stereo, I've been thinking for a while about getting one of those wireless devices that lets you transmit audio from your PC to a receiver plugged into the stereo. Then I realised I already have hardware that can potentially do this - I have an iPod Touch, and a Wi-Fi network in the house. So, is there some iPod Touch App that will let the iPod act as a Wi-Fi music receiver? And presumably, a corresponding piece of broadcast software for my (Windows Vista) Laptop?

• Limiting use of filesharing services

  - by EpsilonVector

  I live in an apartment with 3 other roommates, and we share the internet connection though a wireless router (Level One WBR-3406TX). One of the roommates is always running utorrent, and it is slowing down everybody's connection way too much. Unfortunately, he feels like he shouldn't have to give up on downloading stuff, and is refusing to stop hogging the bandwidth. I was wondering if there's something I can do to the router configuration that would disrupt his use of utorrent just enough to to make the internet usable for the rest of us, and still have it work well enough for him so that he doesn't start poking around looking for answers.

• Belkin router issue

  - by walr1

  Hi, My cousin and I bought a wireless Belkin router for testing purposes. Please keep in mind for all of our tests there is no ethernet cable plugged in, just the router's power cord. We have been trying to "flood" it with PING requests on its default address 192.168.2.1, but it isn't doing a thing; not even logging any attempts of too many requests. I've disabled the firewall, disabled PING request block, etc. Any idea why this thing isn't being affected? We sent 4 million packets and it hasn't done a thing. Quite odd! Thanks.

• Encrypt LAN and wifi traffic on small private network

  - by Grimlockz

  I need some advice about encrypt all traffic on a small private network running wi-fi and LAN traffic on 192.168.0.x network. The network would comprise of client laptops connecting to the wi-fi router (192.168.0.254) via ethernet connection or wireless. The main purpose of the server is for the client laptops to talk to two servers on different IP's (192.168.0.200 and 192.168.0.201) on ports 80 and 433. My main concern is having packet sniffers and what not getting access to the data. The only ways I see at the moment is to have VPN running on the network or use IPSec policy's to do this. Any other ways guys?

• Internet connection very slow after Linksys configuration

  - by NLV

  Hello We have this network setup Server1 - DHCP server, Domain Controller, AD Lease line for Internet connection From lease line to Linksys router (we dont use wireless though) From linksys to Netgear (24 port Switch) and vonage (VoIP) Netgear to all our machines We configured Linsys with the static IP and DNS server addresses our ISP gave and we have routed it correctly. All our work machines are configured with Get IP automatically DNS server addresses our ISP gave The problem is that none of the sites are getting opened promptly. It is taking around 5 minutes to load google.com. But we are able to ping all the sites. What could be the problem?

• Disabling networkmanager for a specific interface

  - by bdonlan

  I'd like to do some experimentation with hostap without disabling my primary wireless interface. How do I tell networkmanager to keep its hands off a specific interface or interfaces while allowing it to continue managing all other interfaces normally? I'm using Ubuntu 9.04. (Wasn't sure if this should go on superuser or serverfault, as networkmanager isn't much of a 'server' tool - if it belongs on serverfault please feel free to move it) Edit: I've tried adding this to /etc/network/interfaces: allow-hotplug wlan2 iface wlan2 inet static address 192.168.49.1 netmask 255.255.255.0 But this has no apparent effect, even after restarting NetworkManager. Here's my /etc/NetworkManager/nm-system-settings.conf: [main] plugins=ifupdown,keyfile [ifupdown] managed=false Edit[2]: Looks like I needed to restart nm-system-settings, then NetworkManager.

• Sharing Internet Connection in Windows 7 is so much more frustrated than Windows XP

  - by Phuong Nguyen

  Back to the time of Windows XP, from Properties dialog of my Wireless Connection, I can enable sharing and then select LAN network from the Drop Down List and boom, I can share it with my friend. We just need a LAN cable (either cross or not-cross is OK) and his Laptop will get an auto IP to gain access to internet. But now with the new Windows 7, everything starts to suck. I cannot see the Drop Down List any more in the sharing panel and my friends Laptop cannot get an automatic IP anymore. Am I doing anything wrong over there? How can I gain back the peace I used to have with Windows XP?

• Using PC or Mac keyboard as Bluetooth keyboard for iPad?

  - by Kevin Hakanson

  I would like to use my computer keyboard (USB) as a Bluetooth keyboard for my iPad, while I am using it with my computer. I was hoping their was an "app for that" that I could run on either Mac or Windows. I imagine how it would work: It would have to emulate a Bluetooth keyboard, and be able to pair with the iPad. Then, when you give focus to this app, it transmits keystrokes from your built-in keyboard out over the Bluetooth connection. Seems simple, but I can't seem to find anything definitive on Google. Has anybody done this? I figure this is cheaper that buying a Apple iPad Keyboard Dock or a Apple Wireless Keyboard from the Apple Store. Also, it's one less item on my desk, which gets cluttered enough with one keyboard.

• Mac internet problems

  - by Bradley Herman

  Our office is set up with mostly macs (7 of them) but we do have a windows laptop and a windows desktop on the network as well. The network is configured with a modem going into a switch/router throughout the office to the computers, along with a wireless router. Everything runs fine most of the time, but periodically while using the web, certain sites will stop loading and timeout repeatedly. This usually lasts 20 minutes or so and can be incredibly annoying. Resetting the modem/router and/or rebooting the computer never helps. The weirdest part is that in almost every case, the websites are fine on our Windows machines. I frequently use github, google, Stack Overflow, and jQuery reference and I can count on the sites being unavailable to me at least once a day. While I can't get them to load, I can spin my chair around to the windows server behind me and load the sites just fine. Any idea what the hell could be going on here?

• Block P2P traffic on a Linksys router WRT54G with Tomato firmware

  - by Kami

  I'm running a small wireless network (6 to 10 users) on a Linksys WRT54G with Tomato firmware sharing an Internet connection. I don't want the users to download files with BitTorrent (mainly used) and other P2P apps. I've also found some solutions about lowering P2P traffic priority using QoS. I really need to ban P2P traffic. Does anyone know how to setup some rules to deny that kind of traffic? I've tried to setup an Access Restriction Rule: However it's not working at all.

• Web connection speed issue

  - by Iroll750

  I encounter a strange issue with my web (wireless) connection on my laptop (Ubuntu 11.10) I'm able to have 540kbps (down) on all computers in my house (including laptop at the same distance from the box) except me. When i do a speed connection test, i can have this optimal speed immediately after booting. As i surf on the net, watching videos, download things, etc... it becomes slower progressively until 100-110 kbps and the speed remain the same until i reboot. I tried to figure out if a process consume bandwith in background with nethogs but i found nothing suspicious. Any ideas ? Thanks in advance for your help !!

• Slow download speeds on MacBook Pro

  - by Austin

  Just as the title says, I am getting very low download speeds on my MacBook Pro. I did a speed test at speedtest.net, and am getting 7 MbPS down, .5 up. However, I can only seem to get 270 KB PS max (averaging 100 K), whether on my school's network or on my home network, wired or wireless. I am on Mac OS X 10.5.8, with Google Chrome. My ethernet settings (under System Preferences - Network - Ethernet Connection - Advanced - Ethernet) are set to "Configure Automatically", "Speed: 100TX", "Duplex: full-duplex, flow-control", and "MTU: Standard (1500)". As far as I can tell, there are no throttles or anything between here and the ISP, so... Any ideas on why I'm getting such low download speeds?

• Tiny linux box with 2xGbLAN, WLAN and 10MB/s AES throughput?

  - by Nakedible

  I'd like to find a small linux box with the following specifications: Small (mini-ITX size is OK) Fanless Runs Debian At least two gigabit network interfaces WLAN that supports "host ap" with hostapd + mac80211 in AP mode Can encrypt AES at least 10 megabytes per second Total cost $300 or less Solutions from multiple parts also accepted - I can buy an external network card etc. and build the box myself if the components are available. If you don't know about the "host ap" thing, just suggest your solution, I'll find out if I can get that resolved. If I can't get all that, I can possibly skip the "runs Debian" part, and I can definitely skip the hostapd part if the box can be a wireless access point with multiple ESSIDs out of the box. Something like Asus RT-N16 is close - doesn't run Debian easily, and probably doesn't encrypt AES fast enough. Something like Zotac ZBOX HD-ID11 is also close - no idea which WLAN card it has and it lacks second gigabit interface, but otherwise nice.

• Why does WMI Provider Host ( WmiPrvSE.exe ) keep spiking my CPU ?

  - by Sathya

  I generally keep my laptop on 24x7, and at the end of the day it's really annoying to have my thighs burnt because over overheating. The overheating seems to be a result of WMI Provider Host ( WmiPrvSE.exe ) spiking the CPU utilization to 25% every few minutes. Any ideas why this is happening ? I have an HP Envy 14 (w/ the HP bundled crap) running on Windows 7 Home Premium. (Note: Based on @nhinkle's past observations, it seems that HP Wireless Manager might be the culprit, is there any way to confirm this ?)

• How can I make a vpn network login the default behavior for logging into Windows?

  - by Danny

  To login to the machine, I have to login to our domain. When I am at work, the unauthenticated wireless permits access to the domain. However, the internet is not available until I connect via the vpn. From home, I have to connect via the vpn first, then I can login to the domain. I have successfully setup a network logon with the vpn (following the directions found here). And for the most part it works correctly. (There is an issue with logout/login I haven't figured out just yet). As I currently have to Switch User and select the Network Login button, I'd like to know if it is possible to have the network login the default behavior when logging into the system. This is mostly a usability issue than anything else.
