I just spent an hour running a Ethernet cable through our walls to my laptop. I hook it up and it says it's a local only network. So I look it up on google and it turns out it's a known problem! So you guys probably know what it is. My laptop has wifi but I have a rough connection over here in this room... it's probably the farthest you can be in our house from the router. So that is why I want to connect this cable to it.
So I don't really know what to do... I tried a few things like disabling the IPS6 or something along those lines but no luck.
You *believe* it's connected to the router?! You don't know for sure?
Most DSL users have a combination modem+router. It's actually a modem and router combined into a single device. It will typically have 3-4 LAN ports and an Internet port (RJ11) from which you run a phone line over to the DSL service on the wall.
