I have OpenWRT on a NanoHD because I despised having to run their software and they omitted 160Mhz channel width from their limited WebUI. I use it for all devices WiFi 5 or older. The fact I can export comprehensive client information makes it easy to identify any signal problems.
So being able to buy something WiFi 7 with OpenWRT already natively on it fully supported is worth waiting for.
Yesterday I dug out an an old (retired) Ubiquiti AC PRO and installed OpenWRT on it using these instructions, it was easy, worked really well and I like the UI and simplicity
Unfortunately my U7 Pro is not yet supported so, if I want wifi 7 my next AP could be one of these !
