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...

I did it and it still works bridging with linux + 2 wireless pairs.

See my guide http://www.linuxhelp.net/forums/Channel_Bonding_load_balancing_t8478.html
,

the important part was

NOTE : I've had a hell of time making the 2 wireless links work together nicely, in order to make them work in a bonding scenario like this, I had to enable a certain option called MAC ADDRESS CLONING, and had to use different SSID , and different CHANNEL.

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!
