Computer Question: Is My Internet Connection Slow Because of My Router?

This latest computer question comes from someone named Morgan who writes:

“I have a question for you. My internet seems to be very slow.

I am not sure if it is because of the ISP that our family uses or if it could be a problem with the modem or router. Our basement flooded and water got on the router.

The router still works but it just feels like it is lacking power and performance. I was wondering if the reason our internet is slow is because of our ISP or because our router has water damage.

I also believe our router is getting to be quite old as well. It is really impacting my ability to stream videos and play online on my xbox 360. Any advice you can give on this matter would be very helpful.

Thank you for your time.
Morgan”
