Installed fresh version 9.04 from live CD. Wireless network was working. Then it disappeared and came back during a session. Now I can not find it.
I have been looking on google and the forums but have not found a solution. I used to use a wrapper when I was using 8.10 but was happy not to have to use it anymore.

When I try to run RutilT I get this message


"Critical error :
Can't find any wireless network interface.
Code : -3"

After it stopped working I tried to use the madwifi driver that was in
System--> Administration--> Hardware Drivers
That didn't help

I then deactivated it and it still has not worked.

Wicd (I just installed it to see if it would help as I was using "Network Manager") doesn't show any wifi at all

I pushed the wifi button on the laptop to see if it was off. It seems to have no effect.

This happened after I upgraded from 8.10LTS so I thought it was from the upgrade, thus the fresh install. I really do not want to reinstall nor do I wish to use a wrapper.

Please help...[-o<

This is a Presario C700 laptop
