Wi-Fi only works next to the router

[Noremac999]

My Wi-Fi has worked fine far away from the router for a while now but fir the past few days the signal can't reach 5 meters away. The powerline to my computer is fine, however. My router is a Virgin Media SuperHub 2. Thanks. (This is for all devices)

This happens, especially when a large amount of devices connect and disconnect from the router. Usually happens on weekends. Please reset the router by simply unplugging the power cable from the rear for 30 seconds and then plugging it back in. In doing this, the router buffer will clear and the DHCP will reset and reassign IP adresses to all devices in the house.
