ONT Box in Garage, Wired outside through wall - BGW210
Hello - I received the self install kit for 1GB ATT internet. The previous owner has a power box in the garage with the ONT running through the wall to the outside. There are two boxes outside. My question is how do I set up the BGW210 if the ONT box (or whatever it's called) is in the garage and it's already wired through the wall?
There is one wall plate inside the house with two jacks, one that says broadband. There are a couple of other jacks in two other rooms with just the white single connection. Any ideas how to get this set up? Pictures attached. Thank you.
