Also running an ASUS router, but mine’s on stock firmware. I believe the model number on mine is 68CU. It’s been rock solid for like 5 years now. It meets all of OP’s requirements as far as I can tell. My favorite feature is that it has USB ports in the back where you can attach discs/printers and share them on the network easily.
