[BUG] 8812eu not changing wifi channels

aepkolol commented 23 hours ago

Describe the bug I have a 8812au on the gs side which works perfectly, however the 8812eu on the drone refuses to change wifi channels. I can confirm the wifibroadcast@drone service is running and sent the iw command to change to channel 161. However it is stuck locked to channel 1. However it does change to monitor mode. Trying to manually change the channel to 161 gives me this error:

iw dev wlan0 set channel 161 HT20command failed: Operation not permitted (-1)

In the wiki it notes

Check with ethtool -i wlanXX that drivers version is empty (it will equal to kernel version for stock driver and empty for patched driver). NVIDIA Jetson has stock rtl8812au installed. You need to remove it!

however the driver version is not empty, like it is on the gs side with the 8812au. It's reporting the driver as

88x2eu

where the main readme says it should be "8812eu" I followed the instructions of this repo exactly, except for this part from the drivers git repo to get it to compile

Or, for arm64, run:

sed -i 's/CONFIG_PLATFORM_I386_PC = y/CONFIG_PLATFORM_I386_PC = n/g' Makefile
sed -i 's/CONFIG_PLATFORM_ARM64_RPI = n/CONFIG_PLATFORM_ARM64_RPI = y/g' Makefile

I forget the iw command I used, but it listed all the available wifi channels and most outside of a small handful in the 2.4ghz range were listed as "disabled" however it correctly lists my region as BO, and its set as such in the .cfg.

Now, the weird thing is.. I had this working a few days before. I just reflashed the jetson and followed the wiki to the letter. I'm not sure what has changed since, and I can't get it working to where it was before. So I am hoping someone can shed some light on where to go from here, otherwise I'd assume it was a driver/kernel issue.

To Reproduce Install as per the readme.md and wiki

Expected behavior Connection to gs

This is very strange - it should works, but please run the following commands:

sudo ethtool -i wlan0
sudo iw dev
sudo iw dev wlan1 set channel 161 HT20

svpcom commented 12 hours ago

if command (3) will not report an error but iw dev afterwards don't show 161 then it is normal - 8812eu driver doesn't report current channel right

wlan1 is an 8812bu I have attached to ssh into the drone over wifi

This was after a reboot without wfb running.

Device or resource busy (-16) check that no other processes (wpa_supplicant, dhclient, etc) use this card.

aepkolol commented 9 hours ago

Sorry, I realize I did

sudo iw dev wlan1 set channel 161 HT20

but that was targeting wlan1, which I use for normal wifi. Doing it for wlan0 outputs nothing to the terminal, but the channel stays the same.

spiri@mu2:~$ sudo iw dev wlan0 set channel 161 HT20

this is normal. It switch channel, but driver doesn't report it (driver bug, you can fill ticket to driver author)
