Finally I have resolved the ever returning issue with WLAN support on my Acer Travelmate 4310.
The madwifi driver supports my chip (AR5007) and I have no longer any problems with connecting to Wireless networks.
The solution can be found here.
It is not the most user friendly way of getting Wireless to work but it is a way! Just follow the instructions as they are printed.
Oh – remember to reinstall the madwifi driver each time you upgrade the kernel. So remember to keep the driver handy on your laptop.
1.- download madwifi-trunk from here
2.- Extract the tarball and go to the scripts folder and in a terminal execute this 2 scripts as root:
./find-madwifi-modules.sh $(uname -r)
you have to answer r to remove old madwifi modules installed on you system.
3.- Let”™s compile, so you should verify you have kernel-headers and build-essential packages installed. After that just do this in the same terminal:
4.- Now to see if your card is working, load madwifi and restart netwoking:
Or just reboot your system.
