Wireless disappeared


I've got a problem with the WLN connection on Ubuntu 8.04 (same problem appeared in 7.10, before the upgrade). Sometimes at the start-up no WLAN is detected... then, apparently after no reason (for my understanding) after a e-boot the WLAN is there again. Lately I didn't manage to have it back working.
I have the feeling the W-card is not detected: it is a Gigabyte GN-WP01GT.
Further info:
iwconfig gives:
lo no wireless extensions.

eth312 no wireless extensions.

Hey Onit72,
Have you tried using add/remove application to download one of the wireless Lan management tools such as KWiFiManager or SWScanner. I had the same problem on two computers but it was fixed by doing this.
Let me know how you go.

Check out the madwifi-hal package. It solved my Atheros related problems where the standard madwifi package didn't.

I tried first to install the madwifi-hal with the following procedure (found on the web) as it was the fastest try:
"gksudo su
cd /usr/src
apt-get update
apt-get -y install build-essential linux-headers-$(uname -r)
wget http://snapshots.madwifi.org/madwifi...0080903.tar.gz
tar xf madwifi-hal-0.10.5.6-r3861-20080903.tar.gz
cd madwifi-hal-0.10.5.6-r3861-20080903
make
make install
echo ath_pci | sudo tee -a /etc/modules
modprobe ath_pci
"
After a re-boot nothing changed.
If no other ideas I can try to replace Network Manager.
