After today's update, my xbox360 won't connect to my wireless network at all. It detects the name of the wireless network but cannot connect to it. When I test connection it fails as well.
If I connect xbox directly to my modem with an ethernet cable, the network test detects the internet but does not connect to Live.
If I connect an ethernet cable from my xbox to my router (obviously my router is connected to my modem for this in the right port), the network test fails at detecting internet.
If I try to use the wireless on the Xbox, it detects the name of my network but fails to obtain an IP address from the router as it states.
During all this, my crappy phone or even my old pc can connect to my wireless network just fine. Even if i disconnect everything else from wireless, my xbox cannot get an IP address. So not that my router can't handle the traffic. In any case, before this update everything was working fine.
Microsoft should not release updates that can cause so many problems.
