Wirles netowrk Problem:IEE 802.1x authentication. Please help!!?!

Hello everyone,

                         a while back i bought a wirless network adapter so i connected it to my desktop (a) and connected my brothers to the wirless network, it was working fine he was surfing the net, and using my printer but i wanted my parents pc (c) to be connected (via a cable), i put the two into a "network bridge" so they can both connect to the internet at the same time. After connecting the two to this bridge i noticed my brothers laptop (b) couldnt use the network i opened the network propertise and it displayed this error 'IEE 802.1x authentication can not operate on peer to peer (ad hoc) networks or networks for which data encryption id disabled'. From this error i deleted this netwotk bridge, the wireless connection still wouldnt work, i have fiddled around with it and cant solve it can any help me with this problem, if you could it would help me greatly.

 

Thanks very much,
