When you restart your modem, it can fix some Internet connection problems, occasionally improve slow connections, and resolve common wireless issues.

To reboot a modem:

1. Unplug the power and Ethernet cables from the modem. Some modems have backup batteries that need to be removed too.
2. Wait 2-3 minutes for the modem to fully power off. All the lights on the modem should be off.
3. Reconnect the power and Ethernet cables to the modem.
4. Wait for the Internet light to turn solid, then check if the internet is working properly.

If problems with your modem still persist, contact your Internet Service Provider (ISP).
