Router and internet problem

It would be a router/internet provider problem

I think that there's a problem with your router or your internet is slow, slow internet would be causing the buffering, and the disconnecting would most likely be because of your router.

It could be an internet connection problem, try restarting the Router.

Intellinet number is 150N 4-Port Router and Cisco 2203C.

Also what if the Internet routers aren't the problem?

So is your issue is with connecting to the router, or is it connecting to the internet? Its possible to connect perfectly to a router but not have internet access. So rule that out for us.

I wonder if your ethernet port is physically loose/defective.

If its connecting to the router just fine but not the internet, than the console may not be the problem.
