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.

Here another user with same issue like @Aleksandr

Same problem with ID 2357:0107 TP-Link TL-WN821N Version 5 RTL8192EU.

I run on 4.19.97-gentoo kernel.
Comment 4 Pacho Ramos 2020-06-10 17:27:18 UTC 
In my case it is "solved" by disconnecting and connecting the USB dongle and restarting NetworkManager. In my case it happens usually when rebooting with the dongle connected all the time

My device is
Bus 001 Device 008: ID 2357:0109 TP-Link TL WN823N RTL8192EU

Running kernel 5.6.13
