I had that bridge plus the “matching “ router RT AC 88U
After 3 routers and 2 Bridges I gave up and Asus couldn’t help, they found issues and changed devices but to no avail
My house has a concrete slab roof so no attic to run cables etc , eventually I bit the bullet and ran a cable across the roof UV protected ( I’m in Johannesburg South Africa hence lots of UV at our altitude)
Definitely not a happy experience
