My internet connection is fine. I have several other internet connected devices that are working properly with no issues.
I have not changed any hardware recently. Same modem and router that I've had for several years with no problems
I swapped cables with a device that was working and my XBox. The other device continued to work and XBox still won't connect, so not a wiring issue
Tried the wireless connection on the XBox as well with same issue.
Tried resetting modem and router, no help
Tried resetting XBox to factory network settings, no help
Tried manual DNS setting, no help
Connection test always fails at internet. Network = Connected then Internet = Fail
Any help would be greatly appreciated. Thanks.
