I have model SM-G990B2/DS 8/256 with latest firmware one ui 4.1. I am having problem suddenly my phone Wifi not connecting to Wifi 6 mode.
When searching for WiFi, it shows my home network with a Wifi 6 symbol, but connects to AC wifi standard. My another phone (OnePlus 9) is connecting to AX standart (Wifi 6) without issue.
I tried to connect 2 different routers with wifi 6. I did a Wipe data/factory reset from recovery menu. And it didn't give any results. It is connects to AC wifi standard, but not AX standart (Wifi 6).
