after I assign my wlan and ether it will stop communicating while it is associating with the other AP either in station mode or ap-bridge, why?

today I went to another shopping centre and trying 10 more brands and only this gigabyte 108 mb was detected by mt but now it doesn't work in bridge mode...

Thanks

You can not bridge wireless client. Its not on the card, its on RFC. You can read a lot of about it if you look after wds and eoip tunnels. That gigabyte card works fine for us.
