Hi,
   I have just bought a new Lenovo Thinkpad T61 with the Atheros wireless card, and installed Ubuntu 8.04.1 via the alternate install CD. However, the OS is able to see the networks that I know usually shows up in my area, but cannot connect to any one of them (the Wifi LED icon on the Thinkpad is off for some reason). I am able to connect with my other laptops, and the encryption is just a simple WEP, so I'm not sure why the Thinkpad T61 with Ubuntu 8.04.1 is not connecting to the network even though it can detect/see the network or at least signal strength...

Any advice would be appreciated!

I'd first attempt a driver  / firmware update and see how you get on from there...

hmm.. tricky..
if the machine you're using to post this has internet access, connect the machines together (crossover cable if you don't have a hub / switch) and share the internet connection

I had a thinkpad which needed the Wireless card enabled via the Access IBM software..
you may want to investigate the Fn keys.. incase the hardware can be turned on using Fn F5 hotkey..

the T61 has a built in lan card..  or failing that.. a modem for dial up?..

thanks chops_uk. I've plugged in the ethernet cable and got all the updates/packages, and even tried madwifi Linux drivers for Atheros wifi cards, to no avail. It still behaves as if it could detect networks but cannot connect. tried various workarounds, and still did not work:

https://bugs.launchpad.net/ubuntu/+source/linux-restricted-modules-2.6.24/+bug/251263

and many more, but it doesn't work. Although, what does a "network restart" mean from the last one?

I've overlooked answering Envoy's last question. hold for a mo!

Envoy:
Sorry I've not been back to you recently.
I suspect the 'network restart' was a reboot of the wireless router.

The link below which you posted had a great step-by-step.. did you see any difference when you tried it?

Thanks for helping! In the end I just got 8.10 Ubuntu and it worked. Apparently, some OS-level weirdness was causing this wifi bug...
