Linux Ethernet Bridging - Apr 2008 - [Bridge] USB device for Layer 2 Wireless Bridge

Bridging with wireless apparently is not trivial with linux as "Many 
wireless cards don't allow spoofing of the source address" according to
http://www.linux-foundation.org/en/Net:Bridge#It_doesn.27t_work_with_my_Wireless_card.21

Basically, I just want a USB wireless device, that works for Ubuntu 
Gutsy out of the box, supports WEP, WPA, bridging and that won't give me 
any hassles under linux. I'm prepared to pay for it too, if need be! 
Does such a thing exist? I don't feel hopeful after reading the above 
link...

Please excuse my ignorance, but doesn't the above link assume
that brctl and ifconfig will work bridging wireless and ethernet?

I could not get a bridge between my wireless (using the ipw3945 driver)
and eth0 interfaces to work.

As I read
http://www.linux-foundation.org/en/Net:Bridge#It_doesn.27t_work_with_my_Wireless_card.21



it seems to me bridging wireless and ethernet won't work in the most
common cases. Is that true at least?

I would really like to create a layer 2 bridge between my ethernet and
wireless networks, but right now have no clue how to continue... brctl
and ifconfig did not work for me with my hardware... Any help or
enlightenment appreciated!
