IR/RF blaster w/ 5Ghz wifi?

I’ve got a Broadlink RM4pro which- after wasting about 2 hours connecting it to my WiFi- finally works reasonably well.

The problem is, my AP puts out a pretty lousy 2.4Ghz signal and I’d rather shut it off completely and have everything on 5G.

Anyone know of a similar device that has 5G wifi capability? Or a DIY project maybe based on the ESP32-C6 module?
