Zebra WT6000 disconnections on 305CX with firmaware 10.6.2.0

[jeff114]

Hi,

we have about 80 APs 305CX in a warehouse and we use some clients Zebra WT6000.

Since upgrading firmware from 10.5.2.0 to 10.6.2.0 we have lot of deconnections with this clients. If we downgrade to 10.5.2.0 everything runs fine.

On 10.6.2.0 we disabled 802.11ax on 2.4ghz and 5ghz  but didn't change anything.

My question: what could cause this problem, is there a workaround to apply to 10.6.2.0 firmware?

Best regards,

jeff

Hello Jeff,

Rule of thumb, when you push a major firmware upgrade (10.5 to 10.6), you should follow it up with a complete config update as well. Do not do them simultaneously as the config update will supersede the  firmware upgrade and this does not help. 

Steps to properly upgrade the APs:

1 - In Manage > Devices, select the APs to upgrade > Hit UPDATE DEVICES

2 - Uncheck "Update Network Policy and Configuration"

3 - Check "Upgrade IQ Engine and Extreme Network Switch Images" > Click PERFORM UPDATE

4 - Once the AP/s is/are back online, reselect the same APs > Click UPDATE DEVICES > Select "Update Network Policy and Configuration" > Select "Complete Configuration Update" > Click PERFORM UPDATE. 

In terms of downtime, take 2 AP reboots into consideration.

I hope this helps,

BR,
