Thanks for the response :)
A direct wired connection isn't possible for me since the router is too far away so would you recommend me just buying a wifi card and skipping the cable/extender setup altogether?
My desktop PC has no wifi card but I can't connect an ethernet cable directly from its LAN port to the router as it is too far away. So I bought a wifi extender and my ethernet cable is plugged into that. The router is only in the room directly underneath my bedroom so its not like the router is...
