Hello, I've got a question regarding my home networking.

I stay in a double-storey house and wifi connection in certain areas can be quite bad. Currently I am using 1 router and 1 modem at the same point.

However, my electrician has routed cat6 cables within the walls from the modem/router point to other areas of the house so that my TV and PC can have wired connection. Even though my PC has good wired connection, the room in which the PC is in has quite a bad wifi connection. I am wondering if there is a device which I can plug into at the PC point to act as another Wifi point?

Thanks for the information. How do mesh system compare against using an old router for wifi coverage? And do I need to do some configuration on the old router for the wifi access?
