I flash image rk3568-eflasher-friendlywrt-21.02-20240314.img to eMMC on the R5C.

I connect an ethernet cable from my router to the WAN port of the R5C.

I connect an ethernet cable from the LAN port of the R5C to my laptop.

I reboot the R5C. My laptop acquires an internet connection. So the above setup seems to be working so far. I am able to ssh in from the laptop to the R5C. Now I try to enable wifi on the R5C but I cannot get it to work.

I point my browser at http://192.168.2.1 and I authenticate. I go to Network / Wireless. I see an entry for SSID, I click Edit. Under Advanced Settings, I change the country code from CN (China) to my country, BE (Belgium). I click Save, Save & Apply. Then I click Enable. Back on the main page it displays the error Wireless is not associated. I reboot the device, the error is gone:

The SSID is not visible, neither from my laptop nor from my cell phone. Under Operating Frequency, Channel is set to Auto. I saw a post online somewhere saying that this is bad. I try various other values for Channel, e.g. 165 (5825 Mhz). This does not fix the problem.

I have attempted to tinker with many of the other values in the menus. No matter what I do, the SSID never becomes visible, neither to my laptop nor to my cellphone. I would be grateful for some help.

Here is the output of iw list:
