1. Shut down the computer/phone/printer/tablet. Turn it back on. Simple, right? This one easy step can fix many problems especially if you haven’t turned the device off and on again in awhile. Printers rarely get turned off and on so they are receptive to this action.
2. If your internet isn’t working, turn off the modem/router and turn it back on. This can be a tad tricky depending on if you have a modem/router combination or you have 2 separate devices. If you have a modem/router combination, there should be an on/off switch on the back of the modem/router. If there isn’t, pull the power cord out, wait 10 seconds, and then plug it back in.
If you have a separate modem and router, unplug both devices from power. (please tell me you can figure out which is the power cord). Plug in the modem first. Wait 2 minutes until all the lights are on or flashing. Then plug in the router. Try your internet again. This works even if one device is not connecting but all other devices are.
