DHCP connection error

[leejj]

Hi, There were no issues with the Wi-Fi connection until now.

I suspect the problem started after updating to version MR 30.7.1 on the MR30H model.

Since 14 days have passed, I can no longer perform a rollback.

Is there any way to manually revert to the previous version?

I also updated to MR 31.1.5.1 yesterday, but the issue persists.

We do not operate a separate DHCP server and are using DHCP configured on the Backbone.

It has been confirmed that there are no issues with the Backbone, and there are available IP addresses.

I am a beginner in network management.

Yes. Open a ticket to support or call them.

DHCP errors on roams are cosmetic. Are you experiencing any issues or only seeing error logs ?

There is an issue. Customers were able to use the Wi-Fi normally yesterday, but today they are unable to connect.

I do not remember the previous firmware version of the MR30H.

Thank you for your response.
I contacted the engineer and was able to manually downgrade the firmware to version 30.6.
