Our router is currently in the lounge at the middle of the house and our walls seem to be made of lead as wifi is near non-existent in the rest of the house. I've persevered for some time with wifi extenders but these are pretty unreliable so am finally looking to hard wire 3 rooms of the house via ethernet cables. I'd ideally like to be able to take 3 cables from the router in the lounge, take these outside the house and around to our front room, office and kitchen. I plan to install wall sockets in each of the 3 rooms and then use switches to connect to our devices (Or may add a router bridge in each room). In order to get all 3 cables external, are there any alternatives other than simply feeding all 3 directly through the wall and out (as this won't look the tidiest). I'd originally considered adding a wall socket in the lounge to take the cables out however i understand that the socket can only have 1 output, so i'd need 3 individual sockets next to the router? I'm very new to this kind of setup so please go easy on me. Any ideas/advice would be appreciated.
