I am trying to install the TP-Link WN-823N v2 usb dongle (Bus 001 Device 005: ID 2357:0109 from lsusb) in NVIDIA Jetson Nano (stock image, Ubuntu 18.04.3 LTS). I have followed the instructions in the README. The wireless networks appear correctly but I cannot connect: it keeps asking for the password (even though it is 100% correct).

Also, using nmcli dev wifi I see that the signal strength is 94% and the rate is 2Mbit/s.

Some debugging output:

I'm not sure if the problem with the password is related to a NetworkManager bug.

Thease read https://github.com/Mange/rtl8192eu-linux-driver/issues/46#issuecomment-325977795

And check also issue #57

The wifi.scan-rand-mac-address=no line is already there. Also, the rtl8xxxu driver is already blacklisted.

Can you please test this branch? https://github.com/CGarces/rtl8192eu-linux-driver/tree/realtek-5.x.x

The Makefile does not have an CONFIG_PLATFORM_ARM_AARCH64 = y entry. Shall I edit it manually?

Using the above entry CONFIG_PLATFORM_ARM_AARCH64 = y the problem is still there. However, in dmesg, now I see the following:

Try to reeboot? https://forum.manjaro.org/t/solved-cant-connect-to-any-wifi-network-using-rtl8192eu-dlink-dwa-131/92023/26

I'm not sure if I should merge the 5.x.x branch, I don't now if it will cause more problems than solutions.

The reboot did not help. I also tried connecting to an open WiFi to make sure the password-check part is not the problem here. Same result, no connection to open WiFi SSID.
