I have some issues to make a WiFi module based on Ath9k chipset work. The WiFi module is this one. It is based on Ath9k in which I’ve followed the following link to install the firmware and executing this command ```
sudo apt install firmware-ath9k-htc
I have the image version 4.9.201. And when getting the card information this is the output:
Hi there, I still have problems to make the Wifi card work in a Jetson Nano development kit. Even after installing the firmware, still the card cannot detect networks. Find enclosed some outputs. Could you recommend a procedure to make it work (ideally, without kernel compilation). I’ve seen using modprobe, it detects the ath9 files
thanks for the advice. the link solution says to add this line intel_iommu=off, however, I don’t know where/how to add it. The content of the ath9k_htc.conf contains options ath9k_htc use_dev_fw=1. Does it mean the firmware is correct? I’ll try to contact the card provider too.
As I said we don’t verify such wifi card. Thus, I also don’t know what error that is. This sounds like vendor driver specific bug. Check your syslog and dmesg to see if any error. Check if someone else hits similar error log before.
