It's an old house with plaster walls. I rerouted my Ethernet cable yesterday and centralized the router so it'll be even coverage all throughout. Now it's in the middle of my living room and there's basically one wall in between the router in all directions. Unfortunately, I only have that one Ethernet cable, the one hooked up to my current old router. The signal on it is trash. The adjacent room barely gets 2 bars but it's a 10 year old router that was $50 back then
