Top modem troubleshooting tips

Slow or spotty internet connection? The best place to start is rebooting your modem/router.

Is your firmware up to date? Modems usually update themselves, but you can check the settings to see if there's an upgrade available.

Tried the above and still having trouble? In more severe cases, a modem reset can solve the problem.
