Two days ago i had been prompted to do an xbox live update. I did that, and since then i cannot connect to xbox live wirelessly. I moved my xbox downstairs and connected fine wired using Ethernet. However wireless i cannot connect. I have gone through all the troubleshoots. My MAC filtering is off, my DHCP setting is on. I know my password, and am wirelessley connected all my other devices apart from my xbox. I tried manually entering my IP address, but when i enter my Sub Mask it says it is invalid.
I have tried everything anyone know what to do?!
