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
