Built-in Wi-Fi chip on my R1S-H3 does not seem to be working. Tried it on the image provided by FriendlyWRT but no signs of WLAN0 interface, or any Wireless tab on the web configuration panel.

Any guidance or troubleshooting techniques?

Hey, I had a similar issue as the guy above. I tried installing NanoPi-R1 images - 20.02.1_buster_current_5.4.20 and 21.08.1_buster_current_5.10.60 on my R1S-H3 and was unable to activate the onboard Wi-Fi. I also tried building Armbian manually and was also unable to enable the Wi-Fi. Any guidance ...

I have tried installing the FriendlyARM image for R1S-H3 but it doesn't have any Wi-Fi Network Adapter. Any guidance possible?
