first of all, I have been googling this in and out finding somewhat similar problems, but have been unable to solve it on my own. I am sincerely sorry if this is a known problem and have a known solution, and I just didnt search well enough.
I just installed fedora15 and as the topic states am unable to connect to my wireless network.
I have a D-link usb dongle, G-122, with the Ralink rt2870 chipset. (Rev. E1) The password is 100% correct, and I have tried both hex and regular.
All the networks show up, but it just keeps giving me the "Authentication required" popup after a couple of minutes trying to connect.
I had the same problem with Ubuntu 11.04, but didn't have the problem in prior versions of Ubuntu.
Do any of you gurus know a fix for this?
PS. I am unable to connect to the router through cable.
