[SOLVED] Why isn't connman showing WiFi?

Enrico1989 · Yesterday 05:50:38

(I should have probably asked this question before Guidance in migrating from Connman to iwd+impala for ethernet+wifi.)

I installed connman when I initially set up this system 8 years ago or so, and the service is enabled and therefore has been running everytime I used this system, and I haven't used it to switch to WiFi for 7 years or so.

But I did use WiFi at that time, years ago, just to experiment; I even set up port forwarding for both ethernet and wifi, so I could SSH into my system regardless of whether it was connected to internet via ethernet or wifi.

Then I didn't need it anymore, years have passed, and now it looks like connman is only aware of bluetooth and ethernet:

$ connmanctl
connmanctl> services
*AO Wired                ethernet_e0d55e2dee05_cable
connmanctl> technologies
/net/connman/technology/bluetooth
  Name = Bluetooth
  Type = bluetooth
  Powered = False
  Connected = False
  Tethering = False
  TetheringFreq = 2412
/net/connman/technology/ethernet
  Name = Wired
  Type = ethernet
  Powered = True
  Connected = True
  Tethering = False
  TetheringFreq = 0

I must have caused a breakage during these years without realizing it.

In the meanwhile I've changed ISP and router, but this should have nothing to do with the fact that my system has WiFi. Unless my mobo's wifi support broke at a hardware level?

The package wpa_supplicant is installed, the iwd package too (I don't remember when, maybe some very old attempt), but the iwd.service is inactive and disabled, whereas connman.service is active and enabled, so I think the answer is yes/yes.

It looks like it isn't?

What about the rfkill part of that command?

Post a complete system journal

sudo journalctl -b | curl -F 'file=@-'  https://paste.c-net.org/

Random guess, you never installed linux-firmware-intel on this machine?

Ops, I forgot:

Not since mid 2021, that's how old my bash shell history is.

The firmware split happened last year: https://archlinux.org/news/linux-firmwa … ervention/ -- you will have gotten a list of firmware packages as optional new ones to install. And the journal confirms it your iwlwifi doesn't find it's firmware, so install that and reboot and retry.

Enrico1989 · Yesterday 19:44:50

Weird... That was 2026/06/13, and here's what my shell history contains:

$ history | grep linux-firm
17959  27/06/25 12:16:42 pacman -Rdd linux-firmware # pacman -Syu linux-firmware
17960  27/06/25 12:16:54 sudo pacman -Rdd linux-firmware

So I didn't miss the news, but I messed it

Jun 11 23:52:46 greywarden kernel: iwlwifi 0000:04:00.0: no suitable firmware found!

pacman -Qs firmware # lacks intel

Please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.

That worked! Yes, I'll do, but there's another weirdness now. If I connect to WiFi, something goes wrong with the "display". It turns out, problem and solution are both described at https://wiki.archlinux.org/title/ConnMa … e_hostname

Enrico1989 · Yesterday 22:20:09

I suppose it's still relevant: if I have SingleConnectedTechnology=false, which according to the wiki should allow being connected simultaneously via Eth and WiFi, then why "scan wifi" errors with "Error /net/connman/technology/wifi: Not supported"? I don't think §4.1 applies, because 1. I don't get that error if I SingleConnectedTechnology=true, and 2.

$ rfkill list
0: hci0: Bluetooth
	Soft blocked: yes
	Hard blocked: no
1: phy0: Wireless LAN
	Soft blocked: no
	Hard blocked: no

Are you using iwd and is that connection active when trying to scan (and SingleConnectedTechnology=false but not connected when using SingleConnectedTechnology=true)?
Compare "ip a" w/ either condition and check/track the journal for scanning failures.
