Can't log in to wireless network except under certain(inconvenient) conditions

Benjamin Lindley · 12-29-2011, 10:35 AM

I've recently switched my OS from Windows to Ubuntu, and I am having troubles with connecting to the wireless network in my house. I have Ubuntu 11.10 installed as the only OS on my computer. When I boot up, no matter how many times I try, it just prompts me over and over and over for my network password.

I've got a process to get it to work, and it very consistently does so. I put in an Ubuntu 10.04 Live CD, then I log in to the network. It works the first time, every time. Then I reboot back into 11.10, and then it logs in automatically. I've had Ubuntu installed for about 10 days now, and this happens every single time. I would rather not go through this process every time I boot up my computer.

My wireless adapter is: Atheros Communications Inc. AR5008 Wireless Network Adapter (rev 01)

If you need more information, let me know, and also tell me how to get it, please.

There is an old bug in the driver for that particular wireless - I don't know if it's been resolved. I was affected by it (or rather a similar one) and my solution (albeit a bad one) was to have my WiFi unprotected on the router but with a MAC-address-based access restriction. Luckily a few weeks later I bought a new laptop.
