Strange behaviour with 2 bt business hub 5 type A

Installing and Using OpenWrt Network and Wireless Configuration
1

Hello,

I've just build one image for my 2 bt business hub type 5, with wpad full inside to enable 802.11r feature.

The 2 routers are used only for AP + VLAN.

The strange thing is that: connecting my phone, a pocophone F1, on one of the 2 devices, the logread show this:

AP1:

on the other one instead, even on first connection or trying to roam, the message is different:

AP2

It's really strange, don't you think?

the built is the same and for the configuration I tried from a fresh firstboot to do a clean config on each of them...

What is wrong?

It seems that on AP1 the 802.11r is not working, but for example searching with WifiAnalyzer for android, each of the SSID has WPA-2-PSK+FT auth possible reported...

Thanks

AP1 is using a DFS channel 100.

fwiw, have you tried the Ath10k 'non-CT' wifi drivers if using 19.07 ?

No, I don't think this is the real problem: the same thing happen even if I disable the 5GHz network devices and use only the 2.4, or changing the channels to 36.

I am using 18.06.7, so I could try to upgrade everything to 19.07, but I have some 841N in my house so it could be a problem (I prefer having the same version on every ap in my house)

maybe I found a solution: on the AP2, as you can see, I have multiple SSIDs (in fact my phone connects to wlan0-1); configuring multiple SSIDs on the AP1 makes this strange behaviour disappear. Strange, isn't it?
