I bought 3 of these a few months ago, and had set them up. When initially setup they were properly working, but right now all of my connected devices are reporting very slow speeds (less than 100Mbps).
I have gigabit and before the access points were giving 250Mbps on 2.4 and around 600Mbps on 5Ghz. I've changed nothing at all. I have reset everything to default and tried again but still everything is slow. I am getting alot of Rx/Tx errors on 2.4 and alot of Tx errors on 5: https://imgur.com/a/dJ4ap0s
I saw that earlier versions of the FW showed these errors are glitched but I'm on the latest version (2.4.0 Build 20181121 Rel. 55897)
