Rock 4 SE - Wifi Issues with two Debian OS images

Hello,

I currently have the issue, that my Rock 4 SE can’t connect to the internet via Wifi.

I have tried these two images (from wiki radxa com/Rockpi4/downloads):
https://github.com/radxa/debos-radxa/releases/download/20221109-1007/rockpi-4b-debian-bullseye-xfce4-arm64-20221109-1447-gpt.img.xz

https://github.com/radxa-build/rock-4se/releases/download/20230207-0209/rock-4se_debian_bullseye_kde_2023-02-07T0210+0000_gpt.img.xz

The first image seems to be for different hardware with no wifi support, so Debian shows no options for wifi access.

The second image has wifi support and shows the right wifi networks, but it is not possible to connect to those networks.

Can you recommend an alternative image, that is causing less trouble?

A little side note: the login information should be also added on this site: wiki radxa com/Rock4/getting_started

(sorry for the broken URLs, but this forum system forced me to do that)

Today I tried Armbian from Github for the 4B (https://github.com/radxa-build/rock-pi-4b/releases/download/20221101-0235/Armbian_22.11.0-trunk_Rockpi-4b_focal_current_5.15.76_xfce_desktop.img.xz). Sadly it is also not helpful with Wifi connectivity.

Where can I find a working image specifically made for the SE version?

I’m using the same Debian Bullseye image.
Wifi works right away along with ethernet with some limits.
I had to switch to Krusader file manager to see my wired NAS.
Your problem might be router placement because the Rock doesn’t have an external antenna.
My router is only 3m away so isn’t an issue.
Also make sure you have the proper power supply for the se, it’s different than the other Rocks.

I have the same problem with rock 4 se.

  • I tried many os-es, like armbian, debian, ubuntu, with kernel 4, and 5
  • the power supply is a raspberry pi 4 power supply with 3A capability
  • the access point is about 1m away
  • it sees the SSD-s but cannot connect
  • I’m using the image now:
    rockpi-4b-ubuntu-focal-server-arm64-20221101-0358-gpt.img

Digging into logs I got:
Feb 25 12:18:54 rockpi-4b wpa_supplicant[558]: wlan0: Trying to associate with SSID ‘homewifi5g’
Feb 25 12:18:54 rockpi-4b wpa_supplicant[558]: wlan0: WPA: Failed to select authenticated key management type
Feb 25 12:18:54 rockpi-4b wpa_supplicant[558]: wlan0: WPA: Failed to set WPA key management and encryption suites

edit:
So the wifi is working with WPA2 access point but not where WPA2/WPA3 is enabled. So something is missing for WPA3 from the rock 4 se system.

You are not the only one

Okay, finally I have found some workaround.

Using this link: https://askubuntu.com/questions/1290589/how-to-use-wpa3-with-ubuntu-20-04

changed from the default sae, to the old wpa-psk with this, and it is started working:

nmcli> set wifi-sec.key-mgmt wpa-psk

So I think the wpa3 key management is missing from the rock 4 builds.
