7921G roaming fail

CSCO12180461 — Mon, 05 Jul 2021 12:47:28 GMT

We've recently upgraded our CUCM environment to 11.5. Everything is working normally except for our few 7921G phones. We were running CUCM 7.1.5 with 1.3.3 as the firmware version for the phones. They worked as expected with this setup. Once we upgraded, the phones are now running 1.4.6.3, and the phones will not roam from ap to ap. If I restart a phone, it will connect to the ap that it was originally connected to when I set it up, but once I walk around with it, it drops the connection. Please advise.

Thanks in advance.

This fails in both of the following environments.

1. At one campus we have a 5760 with 3602I APs. Most devices connect with 802.1x, however, we left a WLAN using WPA2, AES.

2. At the other we have a 4404 using 1142 APs. Again, most devices connect with 802.1x, but we left one WLAN that uses WPA, TKIP.

Let me know if you need more info.

I should clarify that the

I should clarify that the 7921 phones connect to the WPA networks.

Does the 7921 work with OPEN

Does the 7921 work with OPEN authentication?

Unfortunately, no. It won't

CSCO12180461 — Fri, 09 Sep 2016 13:18:23 GMT

Unfortunately, no. It won't connect at all. Not even after a restart.

Hold on, the phone won't

Hold on, the phone won't connect with OPEN authentication????

Run a debug.

Sorry. I made the change to

CSCO12180461 — Fri, 09 Sep 2016 14:00:01 GMT

Sorry. I made the change to OPEN, but forgot to save the changes. Yes, it does connect with OPEN authentication, but it behaves the exact same way. Once I leave the original APs range, I lose the connection. Thanks for the help.

Once I leave the original APs

Leo Laohoo — Fri, 09 Sep 2016 23:15:39 GMT

Once I leave the original APs range, I lose the connection.

1. Maybe there is not enough coverage;

2. Check the APs transmit power to see if they are all running full power or not.

I know that there is enough

CSCO12180461 — Mon, 12 Sep 2016 12:20:34 GMT

I know that there is enough coverage for sure. I can check the power settings today. Keep in mind, these phones were working fine with CUCM 7.1.5 and running firmware version 1.3.3.

Yes, all the APs are running

Yes, all the APs are running full power for the tx power.

running firmware version 1.3

Leo Laohoo — Mon, 12 Sep 2016 23:47:45 GMT

running firmware version 1.3.3.

I can assure you 792X firmware 1.3(3) has significant shortcomings when it comes to roaming.

The roaming algorithm was significantly improved starting from 1.4(3), and later.

Post the complete output to the WLC command of "sh wlan <VOICE SSID number>".
