Having self-exiled myself from XP, I'm an Ubuntu newb. The transition has not been too difficult thanks to the myriad of forums for people like me. But, wireless remains very vexing.

After the initial install, my wireless network was immediately recognized. However, not long after, the connection dropped often, and, eventually I was not able to connect to it. I am only able to access my wireless when the laptop is right next to the router. Even then, it is not consistent. I never had any issues with coverage under XP.

I've read a lot about drivers, but am not sure how to best address it. I use an Atheros Card in a Thinkpad T61.


Thanks

Here is the results from the commands suggested in another thread. I did all of these while having a connection active. I imagine it might be different if I did it while I was having my problems with it.

Maybe there is a better forum for this? Or am just being too impatient?

Have you tried connecting to other acces points? I'm not ruling out that there could be problems with the driver, but I've seen similar behavior caused by some routers, in those cases a reboot or reset of the router fixed it.

No, I have not been able to try other access points. It seems like ubuntu is just having problems finding the signal and therefore connecting in other rooms, whereas Vista is not having this problem.

I guess I'll keep plugging away for a few more days before switching back to Windows.

I read a post in which someone found more luck in switching to Kwifimanager. Can someone explain to me how I would go about doing this?
