This problem started yesterday, but then I tried the connection twice and the second time for some reason it worked. I have an xbox 360 slim and have had it for less than a month. I have run a connection test. I can connect to wi-fi and the internet but not xbox live. I have tried unplugging my router and rebooting it but that did not work.
Modem brand and model number: Linksys E4200 (Cisco)
Router brand and model number: Surfboard 5B6121 (Motorola)
I am using an internal adapter. I have an xbox 360 slim.
I am not sure what UPnP or what a NAT error is, and there are no error codes.
