I am using a Thinkpad T41 with Intel PRO/Wireless LAN 2100 mini pci wireless adapter using Ubuntu 10.04
I had no problems with connection to a Livebox router using WEP security, but I've just changed ISP to Virgin with a Netgear router - this won't work, as I'm told that it doesn't support Ubuntu, but I've connected a spare Linksys router to it, which works fine with my ipod touch and is detected by my Thinkpad, but I can't connect. It's using WPA security, and I'm asked for authentification but it never connects. Ethernet connection is fine, but as I'm currently stuck in bed after an operation I'd like a wireless connection

I recently installed Ubuntu on my parents IBM Thinkpad T41. Everything is great except for the only thing they use it for and thats the wireless internet. When I click on the connection icon on the desktop it picks up a strong signal but wont connect.

I am trying to setup a dhcp server for my internal network. I have two NICs, a modem, and a wireless router. I have my server connected directly to my modem which is providing me with Internet access on eth1 and is working fine. I have dhcp and dns setup on eth0 which is connected to my router. The router shows that it is connected to the Internet but when the router gives a client computer an IP address, the client is unable to connect to the Internet but can connect to the router. I will post my configuration files below with my current configuration.

I just switched from Ubuntu to Fedora 13 because I was unable to get Ubuntu to connect to wireless networks. I tried everything suggested in help and forums, and kept getting "Bad Password" with WICD and Network Manager. Now, with Fedora...I still can't connect.
Problem #1: The guide says to "...make sure that the relevant wireless interface (usually eth0 or eth1) is controlled by NetworkManager," and that I do this via: System>Administration>Network
However, there is no Network option under System>Administration.
Problem #2: I open Network Manager, which displays a list of networks. I click on mine, configure it with WPA and the right password, and it fails to connect: "The network connection has been disconnected."

I was having no problems (that I knew of) browsing the web since installing Ubuntu 10.10 a week or so ago. I was previously trialling Win7 as my customers will likely be using that in the future. Then I wanted to go to internode.on.net. Got the following: Quote: Firefox can't establish a connection to the server at internode.on.net. or Quote: Oops! Google Chrome could not connect to internode.on.net
As it was just after Christmas I thought it must be down, for upgrades or maintenance etc. I later tried to go to Freebsd.org; same error. I've been having a small number of other websites give the same error. I thought nothing of this until I tried it on my wife's macpro. I could log onto all the websites I wanted to and none gave any indication of having been down. Both boxes are on the same adsl connection. I still can't access internode or freebsd on 10.10 yet have been able to access every website on OSX. Now, I was only looking at them for info but am worried I won't be able to access something important. (so far everything I 'need' is working)
ping just drops out. edit: weirdest thing! I just retried and now can not emulate the problem for internode. freebsd still won't show. that is less than five minutes between problems and resolution! I hadn't even posted! But I still would like to have an idea of what is going on. Here is the ping error for freebsd: Quote:

I tried to install Fedora 13 on X201 for a dual boot with Windows. Since there is no CD/DVD ROM on my laptop, I created a new logic partition and put the DVD iso image file of Fedora 13 on this partition. I also extracted the isolinux and image directories out of the DVD image and put it in the partition. I used grub for dos to try to boot to the installation. Here is the command I typed in grub console (For whatever reason, it did not recognize my menu.lst).
root (hd0,4)
kernel /isolinux/vmlinuz
initrd /isolinux/initrd.img
and then boot. The booting process went well until it reached "waiting for hardware to initialize", and then the screen turned black. I thought this happened because Fedora could not recognized (X201 has an integrated Intel HD Graphics adapter). So I tried adding different options to the line kernel /isolinux/vmlinuz , such as "kernel /isolinux/vmlinuz text", or "kernel /isolinux/vmlinuz xdriver=vesa nomodeset", and it still did not solve the problem.

I have Karmic Koala and together with my neighbours we have a W-LAN which I was always using without problems. Now, a couple of weeks ago, my neighbour has changed the password to this W-LAN and since then ubuntu is unable to connect. The network is being recognized, but after the request to unlock a key for the network manager (besides, how can I unlock it once for all?) there comes the window with the request for the network-password, after typing it (correctly), nothing happens. The request for the password comes two more times and then ubuntu states that it is unable to connect.
- We have changed the password again - didn't help
- On Windows I and my neighbours get the connection
- My Ubuntu is able to connect to all other W-LANs

I have an Ubuntu server dedicated to running an openVPN server on my VMware ESX 4 host. On my Windows clients I am able to connect to the VPN; however, on my Ubuntu 10.10 workstation I am unable to connect. Here is what I have done. I have network-manager-openvpn and dependices installed as well as the openvpn package. When I hit the add button in the network manager for VPNs, I fill out all the needed information, but am unable to hi the apply button. I have also tried using the openVPN method for connecting. I download the client.ovpn file from the VPN server, and issue the following command:
Code:
openvpn --config client.ovpn
It asks me for the authentication user and its password and produces this:
Code:

This is completely baffling me..I have a Lenovo Thinkpad X301, which has been running OpenSUSE 11.1 for a while, with vanilla kernels from kernel.org, built and installed in the standard (i.e. not SUSE) way.
A week ago, I dupped to 11.2, and also installed kernel 2.6.38.4 . This was compiled with the gcc-4.3 available under 11.2. Everything worked fine (after the necessary messing around to get X working again).
This weekend, I dupped to 11.4 (via 11.3, of course). After more messing around to get X working again, things were working ok - using the same 2.6.38.4 kernel I'd built under 11.2. I then re-built the kernel. It appears to compile and install ok, and I haven't changed the configuration or the grub configuration. However, it doesn't load. Normally, I just get a blank screen after grub starts it loading. If I boot in basic VGA mode 0, then I get a few lines of messages before it hangs - it hangs complaining about APIC not connected to io bios, and if I boot noapic, it gets a few lines further before hanging after some message I don't know about (allocating 4 HET). I don't suppose that's relevant, anyway.
I've tried three different gcc versions, and two different linux versions (2.31 as well), and the same thing happens. This sounds like something going badly wrong with ld or as or something - but I don't see how anything could have happened that wouldn't have been noticed by thousands of others.

I see the network applet in the panel which shows that I am connected but I cannot access the net. I found out that I had to do this in firefox
about:config --> IPv6 --> disable.IPv6 true
With this tweak I was able to connect to the net. But when I use the Update Manager or Synaptic I am not getting connected, even if I use the cli and do

First off, I should state that I am still using Hardy. I realize that it is many versions from the current release, but my schedule is full and provides little time to ring out a new distro and considering the nature of my problem I don't see much need.
The problem is that I cannot connect to my WPA home network. The wireless card is working because I can connect to any WEP network and before upgrading to Hardy I could connect, although not at first.
Have recently installed WICD which has not helped. WICD tries to connect but reports that it cannot obtain and IP address. Network Manager did not report anything but did seem to translate the password into an encrypted key (saw posts relating to this before but no obvious fix) Since switching to WICD I have not had the opportunity to test connection to a WEP network.
I do not wish to change the security of my home network to accommodate the operating system.

Currently I have an Acer Aspire One netbook with Windows XP on it. I want to switch to Ubuntu, so I have the OS on a flash drive and I can run it fine. The only problem is,I cant see any wireless networks in range. I know the router is working because I can connect with Windows fine. A notification also pops up telling me i have to install missing drivers. But when i click on install, the progress gets to 99% and fails. It says i need the Broadcom B43 driver, but i don't know how to get it.

I've been trying for 3 days now, gone to a couple of ubuntu sites, asked some friends who unfortunately don't have the time to assist me, and gone through several forum responses on here to try to find the solution to my problem.The problem is my inability to connect to my wireless network. I have a linksys USB device for my wireless, and the wireless router is literally right next door to my room. I am able to find my router and my neighbor's router from my computer. However I can not connect to my router. It is WPA enabled, and I have the correct password. It is just unable to connect to the network, it tries for a few minutes then doesn't connect at all and says wireless network disconnected. I am currently hooked up to an unsecured wireless network, but I can't connect to the internet. I am using firefox, but it doesn't seem to connect to any site I try.
Here is the lspci
Code:
captain@The-Ship-Of-Capn-Alex:~$ lspci
00:00.0 Host bridge: VIA Technologies, Inc. VT8375 [KM266/KL266] Host Bridge
00:01.0 PCI bridge: VIA Technologies, Inc. VT8633 [Apollo Pro266 AGP]

and when I ping I type in [URL] in the terminal and all that comes up is
Code:

I just dual-booted my Acer Aspire 3810TZ laptop with Ubuntu 10.04. When I first tried to connect to my home wireless network, it connected fine. However, now whenever I start the laptop, it will not connect. The network appears in the available networks list, but it fails to connect. I know the network is ok, because I can still connect to it fine from Windows.
My network adapter is Intel Wifi 1000 BGN. Apparently (from [URL]) the drivers for this card should be part of the distribution.
I can't understand why it connected once, but (without any changes to the system at all) it won't work now.

I have an Ubuntu 10.10 machine hosting a virtual Windows machine on virtualbox. I have 3 servers I connect to using SSH with password authentication, on standard port (22)For some unknown reason, I have one server that I cannot connect to Via SSH using putty/terminal or HTTP via Browser from my Host nix box, but my Virtual machine CAN connect via both. Same machine, same network, one virtual with a bridged adapter, one physical network card connected to my network.

The problem is wireless connections show up in the connections list but when I try to connect it will just keep trying to connect and will never actually complete. During the connecting process it will constantly ask for my WPA2 key. Wired connection does work but that is only a temporary fix to this problem. The phy0 wlan hard block is stuck to yes also, so that could be the problem.other info:Running Ubuntu 11.04 dual boot with windows vista 32 bitWireless card is Atheros ar5001 on Toshiba satellite laptop

I'm running Ubuntu 10.04LTS 64bit. The desktop running it does not connect to my router or the internet. My mac laptop does. When I installed windows on this desktop, it too could connect. But after reinstalling ubuntu, I cannot. I tried upgrading to the latest ubuntu, but that just bricks my computer. Here is my ifconfig:
Code:
~$ ifconfig -a

Yesterday I tried to connect using my 3G, it has been working since I installed the computer more than a year ago.
When I try to connect I get the following in the syslog (and daemon.log)
Code:
Jun 5 10:50:21 ubuntu NetworkManager: <info> Activation (ttyUSB0) starting connection '3 Bredband'
Jun 5 10:50:21 ubuntu NetworkManager: <info> (ttyUSB0): device state change: 3 -> 4 (reason 0)

After alot of swearing ang scratching of the head I've resorted to trying this from i live cd, but with the same results. I know I've been able to connect using livecd before so I'm a bit worried that something might have happened with the hardware.
What I'm hoping for though is some way to determine that it is the sim-card and/or something on the operator side that is bork.
how to further pinpoint the issue? And/or troubleshoot the hardware? I should be able to send AT-commands directly to the modem, does anyone know how and/or the syntax for establishing the data connection?
EDIT: I'm using an Asus eee 901 with builtin 3G modem.

I had this sticky problem with b43 drivers. Unfortunately, on my Acer Extensa 5620z I'm not even able to connect via ethernet, so I can't download upgrades, driver or whatever. This was initially with 11.04, so I've decided to get back to 10.04, but the problem persists. Then, here we go with details:
networking checked - is enabled.
Ip configuration (I've got static local address) - is ok.
Ifconfig - recognizes eth0.
Iwconfig - recognizes wlan0.
Ping - 100% packet loss, always.
dig - goes on timeout.
netstat -an - doesn't show any connection with external address.

I have a share on my home server with all my music in. When I go to a windows PC (Windows 7) and go to network I can see the share, but when I try to connect in ubuntu by going to places>network>windows network. I get the error: "Unable to connect. Failed to retrieve share list from server". However when I try the connect to server option and specify the IP address its fine. I have tried this with the firewall disabled with the same results. I am trying to get my family to use ubuntu and I don't want them to have tp specify an IP address.

Just purchased a Dell Inspiron 580 MT tower pc with Windows Professional. However unable to connect to the network or the internet when I load a copy of Ubuntu Karmic on dual boot. Windows networking and internet working fine. Is this an ethernet adaptor hardware issue? Broadcom NetXtreme 10/100/1000 Gigabit Ethernet controller-PCI Express card Will try later connecting through a usb ethernet adaptor to see if this is really the problem.
