Hello, I have setup a 2.4Ghz network on my wifi 6 router and it constantly drop out random machines on my network, it's more like a connection refusal. I have over 20 machines shares this 2.4Ghz network. Posting this issue here as a stud, I will update this thread after I collect more data. If you experience the same issue please follow up.

a failure connection trace in my application would look like:
I (4190) wifi:ap channel adjust o:11,2 n:10,2
I (4200) wifi:new:<10,2>, old:<11,2>, ap:<10,2>, sta:<10,2>, prof:11

I (11380) wifi:new:<10,0>, old:<10,2>, ap:<10,2>, sta:<10,2>, prof:11

where a good connection looks like the following:

I (4190) wifi:ap channel adjust o:11,2 n:10,2
I (4190) wifi:new:<10,2>, old:<11,2>, ap:<10,2>, sta:<10,2>, prof:11
I (4190) wifi:state: init -> auth (b0)
I (4200) wifi:state: auth -> assoc (0)
I (4210) wifi:state: assoc -> run (10)
I (4230) wifi:connected with XXXXXXXX, aid = 8, channel 10, 40D, bssid = XXXXXXXXXXXXXX
I (4230) wifi:security: WPA2-PSK, phy: bgn, rssi: -63
I (4230) wifi:pm start, type: 1

as this happens randomly, I have no idea where to look. I tried all possible WPA configurations but it seems nothing matters.
