Ubuntu not seeing my wireless card

Asked by 1fckrules

Hello, I just recently installed Ubuntu 6.10 on my laptop a few days ago, and had everything up and running. Now two days later Ubuntu has lost connection with my wireless card and network manager only sees my Ethernet port. Ive tried to update network manager to the most resent version but it keeps telling me that the program is up to date even though theres a newer version out. What can I do?

Thanks, Dave.

Hi,

Try editing /etc/network/interfaces and commenting out all lines except those referring to the "lo" interface. Then reboot. For example mine looks like this:
---------------------------------
$ cat /etc/network/interfaces
auto lo
iface lo inet loopback

#auto eth0
#iface eth0 inet dhcp

#auto eth1
#iface eth1 inet dhcp

#auto eth2
#iface eth2 inet dhcp

#auto ath0
#iface ath0 inet dhcp

#auto wlan0
#iface wlan0 inet dhcp
-----------------------------------
Also that output you gave included a wireless key. You should generate a new one.

Cheers, Dave.

Above is the lspci readout and the $ cat /etc/network/interfaces looks exactly like what Dave put up, but my wireless is still not working. I've got a Linksys WUSB54G Ver. 4 and a Microsoft MN-720 PCMCIA card and neither of them will work. The Linksys will start to activate then the system will hang and I have to restart. With the microsoft card it will say it's active but the lights don't come on and it won't connect to the network. Any help?

Can you help with this problem?
