Printer "unauthorized" on WLAN

michael_grant_6 — Mon, 18 May 2015 18:39:53 GMT

I am trying to connect a HP OfficeJet 8600 to an encrypted WLAN. I get a connection error on the printer:

"Unable to connect to the network."

WLAN is on VLAN1 and all other clients connect and authorize fine.

SSID authentication: open
Encryption: WPA2
Algorithm: AES

ZD (9.8.2.0 build 15) shows printer as unauthorized. Printer will connect fine to an open encryption SSID.

You might want to try updating the firmware on your printer.

It is on the latest firmware/software.

Sure the radio is turned on? Setup>Network>Wireless - On/Off? Is the 802.11 LED on?

Does the printer support WPA2? You may need to use WPA with Auto for WLAN policy?

Wireless is on and is currently connected to a seperate WLAN unsecured, this is the only way to print wireless right now. The printer connects fine to an Apple AirPort with the same SSID and WPA2 password.

Please open a ticket with support, to review client logs on the ZoneDirector and a wireless trace from the AP (only way to see how Printer is negotiating).

I'm having the same exact issue on a new deployment. HP Printer will not connect to WLAN (ZD1200 w/R600) but will connect fine to an Apple AirPort.

What is the solution?

Thx.

I discovered that it has to do with fast roaming being enabled on the WLAN. When I turned off 802.11r the printer connects. However, I loose FT ability. I have settled for creating a hidden, secure SSID for the printer with the fast transition setting disabled.

Where can I find 802.11r settings in the ZD config setup?

Also, I'm not familiar with FT ??

Thanks for your help.

It might depend on your firmware version but it is in configure>WLANs

Thanks...but I found the problem. The WLAN was set to "Autonomous" and when I changed to "Standard Usage" the printer came online.

No other settings needed to be changed.

My distributor ships out the ZD with "Autonomous" enabled by default....but not sure why.

Disabling 802.11r solved my issues with a DesignJet T520.
