Additional Network Ports for Multiplayer Gaming: Problem with Xbox Live?

Additional Network Ports for Multiplayer Gaming: Problem with Xbox Live?
so I can't play anything online anymore. I can't even check my messages or join parties. It's saying I'm connected to Xbox live because I can see all my friends that are online but at the same time it's telling me I'm not connected to Xbox live? This hasn't
happened until we lost power due to a storm and now I haven't been able to do anything in about a week and a half. I've already resetted my router twice, resetted Xbox 4 times, I've tested connection almost every day, and it says getting pretty old not being
able to connect to any game servers. My brother in the other too my can play just fine. Help?
