TP-Link - Technical Support devices refuse 5ghz band
Hi, i recently replaced my asus routers with the Deco xe75 AXE5400 3 pack. when i set them up a month ago, all bands worked fine. the other day i noticed super slow speeds - turned out all my devices were either on the 2.4 or 6 GHz network. When i tried to force any device to 5ghz it would just refuse to connect. I have tried resetting the network / starting fresh and the problem still persists.
This occurs to EVERY device - devices i know support wifi 5 like 15 pro max or ps portal.
Even my pc refuses to use it and will use 6ghz instead. If i force it to 5 within the app, it refuses to connect at all.
It sucks because i am 8 days past the return window for amazon.
Any ideas on what could be occurring here? i really liked these devices over my asus network.
All of the xe75's are on 1.5.0 which to my knowledge is the newest firmware.
