Shut down your computer or router.
You only need shut down whichever component is directly connected to the modem.
Unplug your modem's power cord from the outlet and leave it unplugged for no less than 10 seconds.
Once you reconnect the modem, wait 30 seconds before starting your computer or router back up.
