[ubuntu] Weak wireless signal in 9.10 with Madwifi (Atheros ar5001x)

view full story

http://ubuntuforums.org – Hi, I am among those unfortunate wretches with an Atheros wireless card (ar5001) and I've had problems with it from the day I installed Ubuntu. I've been using Madwifi to connect to the internet, and it's worked fine, until I lately changed my internet connection, got a new modem etc. Madwifi works still, but the signal is really weak - while not so on Windows Vista. I have found many people complaining about this, but none of the help has been any good. I know it's NOT ipv6 related. Do I have to change the connection settings? Is my card outdated or whatever? Am I using inefficient drivers? Should I just not use Madwifi and rather something else instead? (Trying to install ndiswrapper and get it to work was a dreadful process, so I won't attempt that again.) (HowTos)
