Xbox 360 bridging connection through laptop, not working?!!!?

I have an ethernet cord going from my laptop to my 360, and i have a wireless internet connection in my house. I did the network bridging already by highlighting the LAN/wireless connection, etc. But when I try to run xbxo live it says "Your DNS server cant resolve the names of the xbox LIVE servers or xbox.com". I tried doing the ICS method and it doesnt work either as it says it cant find my IP or something. But how do I fix this DNS problem with the network bridging? BTW my internet still works on my laptop and I already tried doing it with the xbox on/off, resetting the router, etc.
