Hi all,
I’ve mounted a Wifi card into a Jetson Nano based on Ath9k (AR9642). I’ve installed the drivers properly. The interface is visible (wlan0), however, it cannot find any wireless network. In opposition, the recommended Wifi Card Intel 8265 finds the surrounded wireless networks. How can I configure the AR9642 to show the surrounding wireless networks? Any clue? Thanks in advanced!!
Here part of many tests I’ve tried:
cttc@cttc-desktop:~$ lsmod | grep ath9k
