8265NGW cannot join Wifi

Autonomous Machines Jetson & Embedded Systems Jetson Nano
1

I have installed a 8265NGW module card on my Jetson nano B01 4GB (with antennas).
The system boots and can list wifi networks, but it fails to connect to any network, regardless signal strength. After checking the logs it even looks like it is able to exchange DHCP packets but fails with wlan0: deauthenticating from 88:57:ee:82:c7:00 by local choice (Reason: 3=DEAUTH_LEAVING) after a couple of DHCPNAK.

At first I was suspecting power-related issues, but

  • my board is powered by a 5V/4A power adapter
  • I have turned off power save feature with sudo /sbin/iw dev wlan0 set power_save off
  • I have added pcie_aspm=off to my kernel parameters

Below is the output of dmesg when I try to connect the Wifi:

We see two possible hints from the output of dmsg

  • when connecting:[ 80.370052] wlan0: deauthenticating from 88:57:ee:82:c7:00 by local choice (Reason: 3=DEAUTH_LEAVING)
  • when initializing: [ 5.193117] iwlwifi 0000:01:00.0: Direct firmware load for iwlwifi-8265-23.ucode failed with error -2

I investigating a bit the former, and tried to set the REGDOMAIN and disable wpa_supplicant.service (because the network manager is supposed to use its own), but no luck so far.

Any help would be very much appreciated.

edit I forgot to mention that I could not make the DHCP work for my wired connection (I tried several different networks) and had to used fixed settings. Maybe the DHCP service is the culprit

OK self reply. After “playing” around I figured out it is a 100% software issue: my Wifi receives ethernet packets, but somehow DHCP fails. I believe this falls outside the scope of this forum, so let me close this thread.

Just some added info: I have this same issue with a certain WiFi router (which is old) and a laptop I inherited. I could never solve this, but research suggests that newer WiFi software which has been patched against some vulnerability might be purposely refusing to work with an old router with that flaw. Not sure, but I can verify this is not just a Jetson issue (the same issue exists on amd64 and different computers with no NVIDIA software present). I wish I knew how to solve this, but it is correct that it isn’t a Jetson issue.
