Hello @Andy2244,
Really appreciate your help here
I have already tried to enable it on 5Ghz but it did not fix anything at all:
I want to mention that I am also not getting the full speed on the 2.4Ghz, max is 50Mbps while it should be be at least 150 - 200 Mbps.
Btw, I am getting full speed using the cable connected to my laptop. There is def an issue with the OpenWRT Wireless drivers or configuration.
