Guest Portal not working on 5.2

[Anonymous]

After upgrading our Virtual SmartZone and all AP Zones to 5.2, we ran into an issue with the Captive Portal on our Guest SSID's no longer working on R730's and R610's.  I don't know if any other model had the same issue, but after downgrading the AP firmware back to 5.1.2, Captive Portal was working again.  We had tried factory resetting the AP's, moving them to a different controller on same firmware, deleting and re-creating the SSID's, etc.

Support is working to replicate the issue, but wanted to make sure people knew what we ran into in case you see it as well.

I have a fresh install with vSZ 5.2 and R610 APs. The captive portal first works when we deploy it to a fresh added AP. After some time (days?) it does not work anymore.
We are still in development so I don't know exactly how much time it takes until it stops working. 

Once I could get it to work again when I redeploy the WiFi but this does not last long.
I'll revert to 5.1 as you suggested.

Can anyone give me a hint how I can downgrade the firmware?

Hi Bye,

There are total thee ways to downgrade vSZ.

1st: If a cluster backup was created during last upgrade or before, then you can easily restore it and system will downgrade to previous version with all the settings.

2nd: If you don’t have cluster backup but a configuration backup was taken and available, then you can downgrade the vSZ using desired firmware or by deploying a new vSZ with desired firmware. Once this is done, upload the configuration backup and restore it.

3rd: If no cluster or configuration backup available then downgrading vSZ will factory reset its configuration and you have to reconfigure it from the scratch.

IMPORTANT NOTE: All 3 ways required downtime as system will restart or reconfiguration will be required.

Hi Bye,

I forgot that it is a "fresh install with vSZ 5.2". In this case you cannot downgrade.

You have to spin-off a new instance on 5.1.2

That isn't my experience. I've literally 1 hour ago downgraded our vSZ-H using the below method.

Once logged into vSZ, navigate to "Access Points", from the Access Points dropdown menu, ensure that you change the View Mode to "ZONE"
then select the zone and from the "More" option select "Change AP Firmware"

Having completed downgrading all our zones from 5.2.0.0.699 to 5.1.2.0.373 our portal is now being received by the guest and are now able to continue to their desired web content.
