This is a T-mobile AC-1900 router flashed to ASUS RT-AC86U on firmware 3.0.0.4.386.4826(note: it's not on the latest firmware, you maybe choose to update to the latest firmware in the UI).

Got this in 2019. Moved to a new location that already came with aimesh system set up.

The item is in used condition with signs of crack on the antenna which doesn't hinder item product functionality.
