For wireless router issues, you might need to reset your router and modem to restore your Wi-Fi network connection. The modem needs to be restarted because they work together.
To restart your router and modem, unplug the router and modem power cords from their power sources. Wait at least 30 seconds, and then plug both the router and modem back into their power sources. The router and modem should fully power up within a few minutes. When you see blinking green lights on the devices, youll know they are fully powered.
[Note] Any device connected to your Wi-Fi network will be disconnected until there is a network connection. The most common causes of Wi-Fi network issues are slow internet connections that frequently drop, lose connection, or have weak signal strength.
