Wireless bridge connection

Sorry if something like this is already up but I couldn't find anything, alright here is my problem. I have a laptop with a Dell wireless 1300 wlan card and what im trying to do is bridge the connection between that and a xbox 360 through the wired connection. Both connections work fine on there own. But when I go to bridge the two the wireless connection disconnects itself. When I go back to reconnect it won't. I don't get an error or anything it says it connects for a second then disconnects again. The wired connection still seems to work fine. I uninstalled the drivers then reinstalled and updated the drivers also for the wireless card. Any help and suggestions would be much appreciated.
