RayKnight Posted November 19, 2022 Share Posted November 19, 2022 I have recently acquired a BPI-M2 Pro with what is supposed to be USB WiFi (Realtek RTL8821CU). I am running Armbian 22.08.7 Bullseye. armbian-config does not recognize any WiFi. The output from lsusb -t also does not show the presence of USB WiFi as expected. root@bananapi-m2p:~# lsusb -t /: Bus 02.Port 1: Dev 1, Class=root_hub, Driver=xhci-hcd/1p, 5000M |__ Port 1: Dev 2, If 0, Class=Hub, Driver=hub/4p, 5000M /: Bus 01.Port 1: Dev 1, Class=root_hub, Driver=xhci-hcd/2p, 480M |__ Port 1: Dev 2, If 0, Class=Hub, Driver=hub/4p, 480M Do I have a defective device, or is the WiFi not actually a USB module? Is there something else I need to try to enable WiFi? Thanks, Ray 0 Quote Link to comment Share on other sites More sharing options...
Werner Posted November 19, 2022 Share Posted November 19, 2022 Providing logs with armbianmonitor -u helps with troubleshooting and significantly raises chances that issue gets addressed. 0 Quote Link to comment Share on other sites More sharing options...
RayKnight Posted November 19, 2022 Author Share Posted November 19, 2022 Output of armbianmonitor -u is now at: https://paste.armbian.com/wotuxihezo Which does have the output from lsusb which doesn't indicate any USB WiFi device. 🙁 0 Quote Link to comment Share on other sites More sharing options...
Werner Posted November 19, 2022 Share Posted November 19, 2022 Do other USB devices like a keyboard or a stick work on the same USB slot? Try using dmesg -w and watch output closely when you plug in and out your WiFi dongle. 0 Quote Link to comment Share on other sites More sharing options...
RayKnight Posted November 19, 2022 Author Share Posted November 19, 2022 I think you are misunderstanding my issue. The BPI-M2 PRO has an onboard RTL8821CU WiFi which is supposed to be available on the USB bus. Plugging in devices on the 2 USB 3.0 Ports and the USB OTG port have the desired results. The onboard RTL8821CU WiFi just is not recognized. I'm suspect I have a defective board, but was hoping perhaps I was missing something! 0 Quote Link to comment Share on other sites More sharing options...

RayKnight Posted November 19, 2022 Author Share Posted November 19, 2022 (edited) I'm powering with a 5V 3A barrel plug power supply. I'm reasonably sure its not a power issue as it has no problem simultaneously supporting 2 USB 3 thumb drives on the USB 3 ports and an SD card reader via the OTG port. I see your lsusb output has: Bus 001 Device 003: ID 0bda:c820 Realtek Semiconductor Corp. 802.11ac NIC Which is what is missing from mine. So it appears I have a defective board! Thanks for the quick responses. Much more helpful than the bananapi forums! Edited November 19, 2022 by RayKnight 0 Quote Link to comment Share on other sites More sharing options...

Ah my bad then. Didn't get that it was onboard. 1 Quote Link to comment Share on other sites More sharing options...
RayKnight Posted November 19, 2022 Author Share Posted November 19, 2022 I have both the BPI-M2 Pro and the BPI-M5 and very much appreciate that Armbian is available for them as it is a huge improvement over stock firmware! Ray 0 Quote Link to comment Share on other sites More sharing options...
