Problem with wi-fi using WPA2

[VBoch]

Hello, 

Few weeks ago my Xperia XZ2 Compact stopped to connect to some of Wi-Fi networks, but other devices were still able to connect to them. System reset didn't help. After I changed WPA2/WPA to WPA on my router, smartphone connected to it. 

What can be done with smartphone to be able to connect to other networks?  

I'm using latest update of software (55.1.A.11.26)

I can report the same behavior. Switching the AP to WPA instead of wpa/wpa2 works, but I wouldn't consider this a solution... All other devices can still connect without any problem (pc, laptop, android tablet, old android phone)

I'm on 52.0.A.3.126 with my H8266

I thinks they are WIFI drivers problem on Pie, I can't get a good connection to a AC wireless AP, at 5 meters it loose conection and on Oreo I have good signal on all my house with the same phone
