I am trying to get the driver for the wireless chip to work on my n100 based minipc

lspci list it as

00:14.3 Network controller: Intel Corporation CNVi: Wi-Fi

After some searching on the internet I found out that it needs the ax deivers, wich in installed from the opkg. when I ran dmesg I got these errors.

I'm kinda at a loss on what to do from here. Can anyone point me in the right way?

Did you install a matching iwlwifi-firmware-something package?

You can also just get the individual firmware blob from here:

Edit: LOL, that was the actual last message in your log.

3

I installed all the iwl* drivers in the opkg repository. Which driver do I need or how do I figure out which driver? According to intel they should be baked into the kernel.

4

Doesn't look like this firmware is packaged at the moment. So just take iwlwifi-so-a0-jf-b0-77.ucode from the link above, put it in /lib/firmware and restart.

I did that and rebooted. Still getting the same error. It seems I already had the latest firmware in my /lib/firmware directory here is an ls of the directory

Clone this repo

Then upload missing files to your router relative to /lib/firmware/
Ultimately firmware needs to be packaged like here
