Debian 12.x iwd not recconnecting on Beaglebone Green Wirelles

General Discussion

Having issue with reconnecting iwd wireless on Beaglebone Green Wireless.
After running connection procedure everything seams to work fine, but after rebooting wireless interface does not reconnect. Everything was working good on 11.8 with wpa_supplicant. Journal reports:

I just pushed iwd (2.11-1bbbio0) i don’t know if it’ll help anything, but it’s currently the latest release from: wireless/iwd.git - Wireless daemon for Linux

sudo apt update ; sudo apt upgrade

Same thing, same issue. Cleared all settings by “forget” and then repeat all steps as described here:

Then reboot and no connection again.

Tried 11.8 with wpa_supplicant on the same hardware - works excellent.

Just a short update on this, still fighitn it in 2.12 iwd, what’s weird, if manually reset it:

sudo systemctl restart iwd

I can get it to come alive… So still very very broken…

Just a nother update, this is now resolved in…

debian@BeagleBone:~$ dpkg --list | grep iwd
ii  iwd                             2.13-1bbbio2~bookworm+20240115          armhf        wireless daemon for Linux

It’s been pretty stable over the last week between reboots and reconnecting…

No luck. Still same old issue. How can I change it back to wpa_supplicant?

7

I’m also finding that iwd does not detect some wireless networks that were just fine in the Debian 10.3 build with connmanctl.

I’m using the same BeagleBone Blue hardware. A network from the (reasonably old) router provided by my phone company is detected fine in both Debian 10.x and 12.x. A WiFi-6 network (from a TP-Link Deco PX50) is detected fine in Debian 10.x but not by 12.x.

8

Hm… It looks like WIFI6 access points could be the issue. I took one of my Beaglebone Green Wireless and tried on couple different sites with both 11.x and 12.x. The issue happens on the site with one of the Wifi6 assess points (Unifi) and iwd.

9

Updates: I shut down WIFI6 mode on access points. Now iwd works ok. Still testing.

Which Unfi Access point are you using? UAP-AC-Lite here:

I have Unifi U6 Lite and AC Lite on the problematic site.
I created additional WIFI network and limited it to 2.4G only. iwd works much better on this network. One more thing, iwd don’t’ like hidden WIFI names.
