HP laser printer fails to connect to Aironet 1815i AP (ME)

Maurice_ · ‎07-03-2021

I'm trying to connect an HP Laser 107w printer to an Aironet 1815i AP. The AP is running latest Mobility Express Firmware 8.10.151.0. The WLAN is configured with basic settings (WPA2 PSK). The printer won't connect. Other devices have no issues connecting to this WLAN. And the printer does connect to a non-Cisco consumer AP just fine.

On the ME client dashboard, the printer's status is shown as "Excluded". Since the printer has no advanced WLAN settings at all, I'm trying to figure out which AP settings might work. The PSK has no special characters. See event log below for details.

Thanks for any hints!

Re-check the settings. Error message says something is failing 802.1x authentication.

Maurice_ · ‎07-14-2021

Thanks @Leo Laohoo,

The WLAN is definitely configured with WPA2 PSK AES. I even created a new WLAN for testing. These error messages apparently are not exclusive to 802.1x WLANs [1].

A debug on the CLI shows this relevant section:

Some sources (like [2]) suggest tuning eapol-key-timeout (default is 1 second). I tried 5 seconds (config advanced eap eapol-key-timeout 5000), but unfortunately this didn't fix it.

Other ideas?

It feels like the client did not reply to the authentication message.
I think adjusting the EAP parameters on the one hand, on the other hand, you can try an OEPN SSID to see if it is caused by the encryption algorithm and whether it is compatible with the client's network card
?

Rps-Cheers | If it solves your problem, please mark as answer. Thanks !

Maurice_ · ‎07-15-2021

An open SSID works, but is not a viable solution. What other EAP parameters could I adjust?

JPavonM · ‎07-15-2021

Can you share the detailed config of the SSID with a "show wlan id <WLAN_ID>" output?

Your debug points to a compatibility issue with some security feature in the client side, but this is not the case as you have all of them disabled (PMF, FT), try disabling some features added on latest versions that could cause connectivity problems such as dot11ax (I think device-analytics is not there on AireOS). Additionally, disable 5 GHz radio as most if not all printers works on 2.4 GHz band only.

wlan <PROFILE> id <ID> <SSID>
 no device-analytics
 no dot11ax
 radio dot11bg

The printer indeed doesn't support 5 GHz, but setting the radio policy to 2.4 GHz only doesn't make a difference. I had tried that before.

I checked the Mobility Express Command Reference [1]. Unfortunately, none of your suggested settings seem to be supported.

The embedded radio module (SDGOB-1392) seems to be used by many HP printers and there are quite a few reports about compatibility issues with Aironet APs. Enabling TKIP seems to work for some users, but I really don't want to go there.

Jul 15 01:36:21.944: f8:0d:ac:eb:a1:da Retransmit failure for EAPOL-Key M1 to mobile f8:0d:ac:eb:a1:da, retransmit count 3, mscb deauth count 0

Means the WLC is sending M1 for the 3rd time but no response back.

But why? As mentioned, the printer connects to other APs just fine (also with WPA2 PSK). And all my other devices work with the Cisco AP. But there is nothing I could change on the printer side. It has the latest firmware and absolutely no advanced WLAN settings. So I have to find a workaround / compatibility setting on the AP.

Factory-reset the AP.

Can you check if 802.11w-PMF is enabled or optional in the SSID? I've suffered this very same behaviour with some devices that state they are PMF-capable but they aren't.

"Client MFP" says "Optional", but "PMF" says "Disabled". Please see full config above.
