Okay, I threw the cable out to the back.
Plenty of extra on both ends to get anywhere in my house or anywhere in the shed. It was totally unnecessary.
This base station/router is so powerful it gives me coverage over the entire property from the far end of the property inside the shed. I could have just put it right outside the house.
That's okay, I'll leave it there, it's already run and it's in a protected space.
Actual Network login was easy. I duplicated my current Network SSID and password and can walk back and forth easily between them. All applications work back and forth as well.
