Can"t connect a Cisco Linksys WET610N wireless bridge to a AT&T 2WIRE router?

hello, just bought netflix for my home, have it hooked to the ps3 in living room, i need to hook it up to the 3 sony blu-ray player in the bedrooms so me and my kids can use the netflix in bed, blu-ray player model # is BDP-N460 they don't have wi-fi built in, so i bought 1 cisco linksys wet610n wireless bridge to start on one of them. need to connect it to my 2wire AT&T router that runs my whole house with no problems (2wire model # is 2701HG-B). I install the disc that the wet610n came with, (followed steps the the letter) it 1.)configured the wireless bridge, 2.)verified the settings, next says GO WIRELESS, so it finds my network, i put in the WEP 10 number security key, again configured bridge, verifying settings and it stops and says "ERROR 109: your device cannot be found using a wireless connection" now i have unpluged both 2wire and wet610n and tried again, same thing, called both at&t and linksys (over 3hrs between both) linksys had me call at&t back to change the channel on my route to "9", still not working, IP address on linksys is 192.168.1.71 and IP on 2wire is 192.168.1.254 i've looked into the ip for 2wire and it shows wet610n on my network, still doesnt work wirelessly. at this point i'm just short of returning the linksys? will this ever work? is it possible? what am i missing? plz help with step by step so i don't mess up any instructions! thanks again just don't wanna sit all day on phone and not getting anywhere! thx again for any help! P.S. email me if you like to make this easier dirtydevil2@hotmail.com thank you mike
