Title: WiFi not working on Ubuntu 20.04 [Print This Page] Author: mutatrum Time: 11/23/2021 21:03 Title: WiFi not working on Ubuntu 20.04 I'm testing the Ubuntu 20.04 image (ROC-RK3566-PC-UBUNTU20.04-GPT-20211012-1456), and am having trouble getting the WiFi network adapter to work. It detects the device as wlan0, but I can't seem to get it connecting. I've tried setting up a wpa_supplicant.conf file, but that didn't get picked up. With nmtui, there is no wireless network. Adding it manually doesn't seem to work either. Any assistance would be appreciated.Author: Liuth Time: 11/27/2021 15:40
Can you provide some logs? Like dmesg or syslog when you try to connect wifi
Make sure your device has an antenna.
Check /vendor/etc/firmware/, which file is nvram.txt link to?
For example: If your device is using AP6255(you can see it on the wifi module of your device)
then the nvram.txt should link to nvram_ap6255.txt, otherwise, wlan0 can't detect any AP
use command to connect to AP:
nmcli dev wifi connect APName password 123456Author: paulmoo365 Time: 1/9/2026 08:57
