Help Diagnosing Connection Issues?

I have cable internet. No pc is directly hooked up. We run 2 laptops and an xBox wirelessly. Same setup for a year has worked fine. Suddenly in just the past week we are experiencing slow connections and frequent disconnects.

When we disconnect, all of us disconnect. But either of us laptop users can get us all back on line by using the Windows "Troubleshoot Problems" automated process thing. It resets a gateway or something, then we're back. Still gawd-awful slow, but back.

How can I determine if this is a local problem, or if my cable company needs a call?

 

Is your modem and router integrated into the same device or separate? I agree the first thing you need to do is reset your network as MA suggested. Unplug the modem, and the router and all connected devices (if connected via Ethernet). Then plug in the modem, wait for lights to settle down, then the router and wait for the lights to settle, then your computers.

I would try connecting one computer via Ethernet and see if it can get out.

Again, if using a separate router, you might try connecting a computer directly to the modem and see what happens. The router may be bad.
