How to power cycle your network devices
A very common troubleshooting step is to power cycle your modem and router.
This purges their caches, causes them to re-establish a connection to your ISP, and reinitialises their configuration.
Power off all devices connected to the router
e.g. the device you're using to play Path of Exile
Power off the router
If your device has a battery, use the device's Reset button or temporarily remove the battery.
Power off the modem
Can't find a seperate modem? These days, many people have a single device that act as both a router and a modem.
