Journal after loading stock driver

Using the default stock driver, my TP-LINK TL-WN823N V2 USB Wi-Fi adapter fails to authenticate with my access point. My network is very standard and uses WPA-PSK. Log attached.

By using a modified driver from Realtek [1], I'm able to connect to the internet just fine.

I've tested the stock driver on 4.12.7 too, and the problem remains the same.

Another minor thing I've noticed is NetworkManager shows all the access points as having the lowest signal strength, but when using the Realtek driver they are as expected.

I've previously had issues with an earlier model of the adapter, which had the rtl8192cu chip.

Sorry, pasted dmesg output in the wrong place :(

I confirm the same problem with the Mercusys MW300UM adapter, kernel 5.3.11. The adapter sees access points, but when trying to connect, dmesg shows

wlan0: authentication with 00: 18: e7: be: 6b: de timed out

but with the third-party module from the link above - everything works fine.
