For the last few months I have been using a Motorola NVG510 router/modem from AT&T as my wireless access point to connect to Xbox Live.
Today I set up the router/modem to act as a bridge so I could use my Netgear DGN 2200 which has much better range and allows for greater DL and UL speeds.
Since doing that my computer connects perfectly fine and I can surf the web all I want. Except my game systems will not get past the test connection screens.
The Xbox One says "DNS isn't resolving Xbox server names"
I can't figure out how to get it to go past this screen and the online troubleshooter is no help.
