My wifi isn't great, I've connected my work laptop by Ethernet and it's made a world of difference but the router isn't close by, I'd like to avoid an ugly cable running through my hallway! I have a phone line/Ethernet socket in my office, but don't quite understand how it works, I assume I can't just plug the Ethernet cable into the wall, would I need to move the router into there??
(Sorry can't test it this second as can't unplug for a couple hours!)
