• Are all bluetooth adapters the same ?

  - by ldigas

  I have a wireless bluetooth mouse which I'm not using. It used to have a bluetooth adapter with it, which I lost a long time ago ... (don't ask). Since my regular mouse just died (bad contact in cable from messing with it too much) I was thinking of buying just the new generic bluetooth adapter ? Are all those adapters the same thing ? Or can this that came with the mouse be somehow different ? Edit by ldigas: How would one find out what bluetooth standard/class/adapter one needs ? (I don't see anything useful written on the sticker on the mouse). Or to put it bluntly - will it work with this one in your opinion ?

• Home network with Windows 7 as router

  - by Michael

  Background: I have tried to use routers, but so far all of them can't handle the bandwidth, number of connections eventually limited by the hardware resources, so overall the home routers are decreasing the internet speed. I went through DD-WRT and stuff like that. Question: What I want is to use my Windows7 PC as router. It has 2 LAN cards. I'm going to connect to this router another desktop 2 pcs and notebook through wireless router. The main question is what is the most efficient way to turn this Windows7 box(and I need Windows for native NTFS support) into router with NAT/Routing/Firewall functionality? Is there any routing software recommended for this purpose or I should just use windows native "Internet Sharing"? I'm going to run SIP phones in the LAN, so I need friendly NAT(Full cone perhaps). Also I'm going to have FTP server on that Windows7 "server" PC. As firewall I'm thinking about Comodo. Need to drop all incoming, unless explicitly allowed.

• Which linux distro for a laptop in windows environmet?

  - by Dev er dev

  I just got new laptop at work. What would you recommend as a linux distribution for it? All other developers are working under windows, and use windows tools. I'm currently using ArchLinux, but want to change it. I don't want to waste time configuring wireless, windows network shares, network pritners, projector, etc ... I want this stuff to just work, while still having sane and stable development evironment and tools. Is Ubuntu a good choice for this? I use gentoo at home, but don't think it is a good match for work environmet. EDIT: Note that we are working on cross platform apps, and deployment platform is almost always linux. There are very few windows apps that I have to use (like MS Project). It is just that everything else is windows centric. I use linux because I feel more productive with it, even if I have to dual boot to edit MS Project files.

• Double default gateway ubuntu server

  - by Elena

  I've just installed an Ubuntu server 9.10 on an EEEBox. This is my /etc/network/interfaces # The loopback network interface auto lo iface lo inet loopback auto wlan0 iface wlan0 inet static address 192.168.48.16 netmask 255.255.248.0 wireless-essid mynet auto eth0 iface eth0 inet static address xx.xx.xx.xx netmask 255.255.255.224 gateway xx.xx.yy.yy When I restart /etc/init.d/networking, I can access the eth0 ip address from the internet and I can ping the machines in my wifi network mynet. Everything works fine and I have one default gateway. But after some time if I check again the route I just find two default gateways: one is correct and is the previous one, but the other is the one of the wifi network. I have a quite low signal of mynet where my server is and sometimes the wifi just disconnect and then reconnect again. Then I think that this can be a problem and the dhcp of the wifi net, when reconnecting it also add a default gateway. Any idea on how to resolve this issue?

• network timeout how to analyse problem

  - by elhombre

  In the last three month I was experiencing that my internet connection started to get very slow and websites had long time to load. The first thing I made was an ping to www.google.com which showed that I was loosing pakets. Here some of the results: 64 bytes from 74.125.39.103: icmp_seq=2909 ttl=53 time=48.222 ms Request timeout for icmp_seq 2910 Request timeout for icmp_seq 2911 64 bytes from 74.125.39.103: icmp_seq=2912 ttl=53 time=44.372 ms Days later I had to reset my router because it wasn't able to establish a correct network connection. It was after the reset when things worked again for some days. But later the same network timeouts started to happen again. I would like to know how I can analyze the problem to get to the source which is causing this timeouts. Which steps do you take to circle in this Problem?

• Ubuntu not connecting to network in Hyper-V

  - by soandos

  I am unable to connect the Ubuntu guest (both 12.10 and 12.04) to the internet via hyper-V. Here is what I have done so far (with much thanks due to @Kronos's blog post on the topic): Created a switch in the switch manager with connection set to external, selected my wifi card (Intel Centrino Ultimate-N 6300 AGN). If it matters, the Microsoft Filtering Platform is checked under extensions. Added this switch to my Ubuntu guest. I also tried a different wireless card (Aethros 9285) same issue. Connecting through my wired card works just fine (assume that I select that card, and I am wired in of course). Making it a legacy network adapter does not fix the issue. Ubuntu can see this connection, but is unable to connect to it. What follows is what I attempted to do to get Ubuntu to connect: Start and restart the network manager Restart the machine Verify that it could in fact see the adapter (resulted in device not ready a few times) How can I get this to work properly?

• Sharing laptop's internal optical drive running windows XP Media Center Edition with Netbook running

  - by Col

  just got a new HP netbook with no optical drive and guide said I should be able to share the optical drive of another windows computer. The netbook is running Windows 7 and the laptop, also HP, with the internal optical drive is running Windows XP Media Center Edition. I have wireless network that both the laptop and netbook access without a problem. The instructions did not seem to work in my case. When I right clicked on Properties of the optical drive and went to the Sharing tab, there was no selction for Advanced Sharing as the instructions said. XP made me go to Network wizard and set up a network, (which I already had). After doing that I could not access the drive from Windows 7. Has anyone benn able to do this?

• Bonjour/mDNS Broadcast across subnets

  - by Matthew Savage

  I have just setup a new OSX Server in our office and verified that everything is working fine over our wired network (192.168.126.0/24). The problem that I am having is that our clients (Mac Laptops) are mainly connected via Wireless, which are running on a different subnet (192.168.1.0/24), and the mDNS Broadcast isn't reaching this subnet. The network configuration is somewhat foreign to myself (I don't manage the network in this location, but as of just recently the servers), however I don't believe there is any firewalls or routing rules between the two subnets which might cause the traffic to be rejected. I'm wondering if this is simply the mDNS broadcast not able to broadcast over the two different subnets (I'm still reading up on broadcast to understand it more) or there is something else which I might be able to try.

• Print server not being recognized after switching router and upgrading to 64 bit

  - by picardo

  I recently upgraded Windows 7 from 32 bit to 64 bit. I also switched my router from a very old model of Netgear to TP-Link. Before these updates, I had been using a USB print server by IOGear. After the updates, I took care to reinstall the drivers for both the print server and the printer, and picked the option to install a printer via TCP/IP, but no matter what I did, the driver software couldn't locate the print server on my network. I hit refresh, restarted my machine, turned off the firewalls and tried again. Still nothing. I'm at my wit's end. What else is left to try? Edit: More info. The print server is connected to the router via LAN line. The computer is connected to the router with a wireless connection.

• Connecting to Aerohive APs from Laptops running Win. 7 using authentication from a Windows 2008 domain server

  - by user264116

  I have deployed a wireless network using Aerohive access points. 2 of them are set up as radius servers. I want my users to be able to use the same user name and password they use when they log onto our domain. They are able to do this from android devices or computers running Windows 8. It will not work on Windows 7 machines. How do I remedy this situation, keeping in mind that the machines are personal machines not company owned and I will have no way to change their hardware or software.

• Juniper Networks SRX240 as a office router?

  - by Jordan Mendelson

  We're a small (7 person) fast growing startup who just got our new office and we're having a 100 Mbps line installed from Cogent. I'm not familiar with Juniper devices, however the equivalent Cisco appears to be rather expensive. Features we'd like: Offsite VPN access (PPTP or L2TP IPsec) - something Mac compatible IPv6 support NAT - ideally supporting multiple outside addresses mapped to VLANs DHCP DNS forwarding would be nice QoS to keep our SIP phones happy (managed through RingCentral) VLANs for guest/internal The device is going to be connected to a set of SIP phones as well as two Ruckus 7962s for wireless access. Eventually I'd like to connect it to a Juniper ESX switch as we grow. Would a Juniper SRX240 handle this ok?

• Why are they putting "processors" on hard drives?

  - by Celeritas

  What does it mean when they have a processor on the hard drive, how does it work, and what benfit does it have? I don't understand - the CPU is the processor and the hard drive transfers it's contents to RAM. Do have additional processors, preprocess the data some how? Here's some examples Western Digital WD Black WD1002FAEX 1TB "Dual processor speed" NETGEAR ReadyNAS 312 2-Bay Diskless Network Attached Storage "Dual-core Intel 2.1GHz processor and 2GB on-board memory" and routers now have processors too, why's that nescecary? I guess it sort of makes sense - some logic needs to happen for the packets to be read in to know which ports to send them out on, but why did old routers not need them? Example or wireless router with processor: "Dual-core processor"

• Securing data sent to an unencrypted WiFi AP

  - by David Parunakian

  The business plan of a project I'm involved in assumes selling certain WiFi-enabled devices to end users. All these devices originally have an unencrypted connection and a standard SSID. The problem is that although the user can connect to it and set both a new SSID and a WPA passphrase, these are being sent to the AP in plain text and thus can be intercepted by anyone nearby with a sniffer. What's the best solution to this problem, and why? Initially set up an encrypted wireless network at the device and supply the user with a printed passphrase Buy an SSL certificate for the AP's default IP address or local domain name (the APs aren't supposed to work as a router and have a captive portal & dnsmasq installed, so all of them can pretend to be myunit.example.com, as far as I understand) Something different Thank you.

• Windows 7 port Forwarding Issue

  - by Elliot

  I can't get port forwarding to work now that I am using windows 7 (64-bit). I am using a wireless connection (no wired connection available). I have the ports forwarded (IP has been double checked, router settings are confirmed), there is an exception for all of the programs in question in windows firewall, and in the resource monitor windows lists the ports as available, not restricted, and yet when I either use a specific program (ie utorrent, DC++, Command & Conquer 3) or check using firefox, the port reads as closed. How do I get the port forwarding to work?

• DSL connection dropping when starting game

  - by bootoo

  New connection set up last week - have called tech support, signal fine, sending out tech guy tomorrow - however i cant make sense of this using Vista, 2wire connection 6mb ATT conn, wireless, i can browse website, stream video from my PC wirelessly to my xbox, watch Hulu in high res, connection seems fine I load up World of Warcraft, i select Enter World and without fail my 2wire modem 'DSL' light goes red, my internet light goes out, im no longer connected, then after 10 or 15 seconds it works again, but game has kicked me Noticed the same thing on opening or closing Utorrent as well No other phones/devices plugged into the phone jacks in the apartment - why would joining a game cause my DSL to drop? i can only guess it throws a bunch of information to the server when i hit 'enter world' and that causes an issue that shuts my connection down or my router hates me - all help appreciated

• Socksify TCP connections reaching a gateway IP -- preferably without iptables

  - by Alexandra Neagu

  I have Virtualbox installed on Debian with a few virtual machines. I can't install anything in the guests, and I use host only networking, vboxnet0. The host IP in the host network is 192.168.56.1, and the guests have static IPs in 192.168.56.0/24. I access Internet with a SOCKS proxy (without authentication) and I would like the Virtualbox guests TCP connections to be sent through the SOCKS proxy. This would also be useful for socksifying external TCP reaching a gateway network card or wireless access point. I looked at transocks, tun2socks, with dante-client, etc., but I don't know how can I achieve this without enabling IP forwarding in the host and using iptables. Maybe to attach somehow the Virtualbox vboxnet0 network to the tunnel tun0 used by tun2socks? Or maybe there is a way to do NAT to tun0 in Virtualbox? I only need TCP traffic and I don't need UDP, not even for DNS.

• internet access options in remote area? (read: no comcast,qwest, etc)

  - by freedrull

  Currently I am living in a fairly "remote" area, in the countryside, and cable internet access through the typical companies like comcast and qwest is just not available here. I've been trying to research other options for fast internet access. There are some small cable companies but they currently do not offer broadband access here. I thought about maybe buying a 3g phone with a data plan and doing some sort of tethering, or perhaps getting an android phone and using it as a wireless AP. This would of course depend on 3g being available here. The only other thing I can think of is some sort of satellite internet service, or doing something crazy like adapting wifi over am radio. Anyone have any ideas, at all, short of moving somewhere else?

• Can't connect to a share.

  - by AngryHacker

  Hello, I have a laptop with a Windows XP Tablet Edition installed. I have several users setup on the laptop (mostly me and my kids). When I try to connect to its administrative share via \DadLaptop\c$ from a Windows 2000 Professional machine, it prompts me for a user name and password. However, after I enter it, it always tells me "incorrect password or unknown username". As a test I setup another share, called "test" and tried to connect to that. It worked fine, didn't even ask me for a password, just connected to it and that's that. All the networking is wireless. I am connecting with an admin account (admin on the target computer). What am I missing? Why can't I connect to an administrative share?

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

  - by Kami

  Hi, I'm running a small wireless network (6 to 10 users) on a Lynksys 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: But it's not working at all ...

• Why every change in Asus UX50v causes screen resolution get lost?

  - by Kaveh Shahbazian

  Why every change in Asus UX50v causes screen resolution get lost? Installing a new application, connecting to another wireless network, change some settings, ... causes this problem. For example after installing an application, UX50v needs to restart. And when it got restarted, resolution would be set to 640x480(or 600x800) and Hibernate and Sleep options are disappeared from shutdown menu! (I have other problems with this Asus UX50v crap too - like I can't update windows 7 because it crashes on Asus UX50v crap - but this one is absolutely ridiculous and stupid!)

• Help changing MAC address in Windows 7 [closed]

  - by Niphoet

  Possible Duplicate: Change MAC Address I need to change the MAC address of my wireless adapter in Windows 7 (Ultimate RTM). I used to do this in XP both directly in the registry editor and with a .REG file I wrote. I have used each of these methods in Windows 7, as well as a few tools I found that are supposed to do this. Every time I change it, I disable and re-enable the network adapter in control panel, but upon running ipconfig /all it still shows my old MAC address. Any help? By the way, I do have Administrative Rights and UAC turned off.
