THANK you very much!
I was following this thread with big interest since last weekend.
Here I found a Wireless card in the trash. An MSI card with a 'Ralink
Technology RT2560, RT2525'.
Under 8.2 it worked perfectly while under current I got a crappy
ethernet address.
Went back to 220194 and could prove that it was working there.
During this process your message came in and I immediately tried the
below patch:
ral0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 2290
ether 00:13:d3:7f:f8:48
nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>
media: IEEE 802.11 Wireless Ethernet autoselect mode 11g
status: associated
Whee!!! Again, thanks a lot.
I do not know if it is the right solution, but it works.
Gruss,
Andreas
