Restart Wi-Fi Router to Fix Wi-Fi Problems
Most of the time, all you should do with your Wi-Fi router is a quick restart and fix the connection issues immediately. Just switch off the router and then turn it on after some seconds to check if you're still receiving slow WiFi speed. If it doesn't fix the speed issue, try restarting your devices. At times, the reason for slow internet speed may just be due to one of your devices and not the connection.
