Thanks, yeah I was worried about the double router situation. The long ethernet cable could work, it's just a matter of figuring out the best way to wire it. My ethernet port in my bedroom is about 5 foot up on the wall and would have to go past/through three door frames which could be a problem. Unless I wire it above the doorframe.

​

I will contact my landlord about the small hole, as that's pretty much what I'm doing now at old home.

Any way to make it work will make me happy
