If you are at home and your internet is down try to check with other computers to see if it works. If not then turn off your modem and router, wait 60 seconds and turn it back on.
Most modems and routers do not have a switch to turn off, you just unplug the power cable from the back of the router or unplug from the wall. Please make sure you don’t unplug the wrong cable. if you unplug any other cable make sure you plug it back to the same spot.
If the internet is still down, Please call your Internet service provider or call me for more assistant.
