I have been running my xbox through a bridged connection from my laptop for the last year. Recently I updated the firmware on my router and now I am getting this error on the xbox. The xbox is the only platform I am having issues with. Both pc's, ps3, and wii work fine. To begin with I should mention that before even getting this far I had to put in the mac address of my laptop for the xbox to even connect to the network. Once I did this, however, the xbox did correctly identify my ip address, dns, addresses, gateway, etc. Even though it did identify these it will not connect to the internet. I have seen people mention that you should plug the xbox directly into the modem bypassing the router to see if it resolves the issue. My modem is my router so I can't do this. I have also noticed a multitude of threads on this but have not seen any resolved.
