NVidia Jetson Nano - no wifi networks (TP-Link Archer T4U Plus v1.0)

hidoba commented 1 year ago

I've successfully compiled and installed the driver (with CONFIG_PLATFORM_ARM_NV_NANO = y). Device is recognized and seems to be down all the time. No networks visible. Device: TP-Link Archer T4U Plus v1.0. System: Ubuntu 20.04.5 LTS Hardware: NVidia Jetson Nano dmesg:

Fixed. Disabled the rtl8812au driver by adding to the /etc/modprobe.d/blacklist.conf: blacklist rtl8812au And then

sudo modprobe -r rtl8812au
sudo modprobe 88x2bu
sudo reboot

I assume it's a device problem that both drivers are triggered?
