TLDNR- Wifi setup to get signal to 25x30 garage 60 feet from house, service comes in first floor 50 feet further from back of house.

Woe is me. Sorry for yet another question.

We have 1000MBps AT&T fiber. Using the Wi-Fi built into the gateway, we barely get a signal to our detached garage.

I failed to add ethernet when I trenched to run electric. Prefer not to because of grounding issues and now there is a sidewalk crossing the backyard.

Currently the fiber connection comes in towards the front of the house. It’s about 50 ft from there to the back of the house. Yard is another 60 ft. Then garage is about 30 ft deep.

Just purchase a set of ASUS XT9 Zenwifi. In testing inside the house I’m only getting around 150 to 160 Mbps on the AT&t gateway Wi-Fi. XT9 is only 100Mbps

If I place the node in the back window of the house, I can get 30Mbps at the closest part of the garage, 10Mbps at the farthest.

Do I need a 3 router system? I could probably run ethernet backhaul to the back of the house, but I don’t know that it will solve the issue.

I tried to talk one of the ATT fiber techs into running me an aerial fiber cable between the two buildings but no dice.

I know a lot of things are on sale right now so hoping I can get advice and get something still on discount.
