after reïnstalling openSUSE 11.4 - no WiFi connection again

Hi all,

I have a dual boot system : Windows XP SP3 and openSUSE 11.4 64 bits, GRUB for boot loader.

Having had problems with my NVidia driver (computer hanging all the time), I reïnstalled openSUSE 11.4 from DVD.

Since then : no more wireless internet-access, which functioned very well before.

So my ESSID and the MAC-address of the router are recognized.*

I verified and re-verified my password, so this is correct.

Strangely enough, my inet addr appears in the local loopback … nothing in wlan0. The kernel driver is the same as in the previous installation rt73usb. I know I had problems with rt2800usb before, so I did not use it.

W>ould you believe it ?
After rebooting for the umptieth time, and having used the same settings as always, my wireless works…

Mystery, mystery …
