My sister had an upgrade to her internet service seven months. Since then, her laptop and table work most of the time (useable internet connection). Since then, her xbox no longer connects to the internet.
What tests can I do to determine what the problem is?
So far, she has powered her router on and off and tested via wireless and wired connection.
Same provider, higher package. Networking isn't my forte so bear with me here please. I feel like I've seen UPnP settings on both network devices and routers. I'll check both places and see if its enabled.
