Lubuntu 10.10 Asus wl-107g


Hi

I have Lubuntu 10.10 on and old old IBM Think T22 with an Asus wl-107g WLAN PCMCIA card installed.. When i first installed the distribution it didn't work. Then i rebooted a couple of times and then it worked no bother, but now it doesn't work again..

The error is basically that it doesn't seem to recognize it anymore.. it doesn't recognise any network hardware other that the built in ethernet card (which for some reason got the name eth2, suggesting that there is an eth0 and eth1 but ifconfig doesn't show them)

How can i fix this?

Thanks

Hi,

Try the '-a' option with ifconfig;
Code:

Notice the difference in the output above. By using the '-a' option you are requesting all devices be shown, even the ones that are down.
'man ifconfig' will get more information.

Hi,

What you see with the 'ifconfig -a' is what the kernel has recognized, even those that are down. If the output does not have a device you expect then that is when you have to start reasoning as to why or what is happening.

I would look at the output of the logs. Start at 'dmesg' to see if the device is listed or sometimes a device can be in the output but not properly identified. That is where you start to trail things. Sometimes it is lack of having 'firmware' in place or even incorrect modules/drivers. You as the admin must learn to diagnose and identify errant things. Then start looking for a solution.

At first I thought it could be udev problem but now it may just be a hardware failure. Do you have another NIC that could be tested on this system?
