Check the cables and power supplies
Make sure all modem cables are firmly plugged in, including the modem power cord,
the cable from the modem to the computer, and the cable from the modem to the wall
jack. Check the cables and power supplies to Ethernet hubs and routers.
Turn the modem off and on and reset the modem hardware
Cycle the power on your DSL or cable modem by turning it off for a few minutes and
then turning it back on. Some ISPs recommend that you unplug the modem’s power
cord. If your modem has a reset button, you can press it either before or after cycling
the power.

supplies, then turn the modem off and on again and reset the modem hardware.
