New - CAX30 Firmware Version 2.2.2.2 Released

Is there a way to DISABLE firmware updates on the cax30?  Or is there an older version of the firmware that supports the ability to disable automatic updates?

I was previously using an older version of the firmware that I manually installed - I think it was V1.4.12.2 or possibly V2.2.1.12.

I had previously manually installed the older firmware because the router would periodically become unresponsive, and I read some forums that said an older version didn't have these issues.

When it became unresponsive, it seemed that some devices that were already connected would continue to work (both via wifi and ethernet), but no new devices could connect with either wifi or ethernet, and many already-connected devices would stop working.  The router admin page would also become unresponsive.  If I rebooted it, it would start working again.

I tried many things - but the thing that seemed to keep things working was to use an older version of the firmware, and then to set up IP reservations for all my devices.  BTW - it is a major pain to set up the IP reservations - it takes an eternity.  I wish there was a way to just import the reservations as a CSV or something.  If I have to do this again, I will have to write a program to automate this.

Anyway - now I see that the firmware has apparently automatically updated to V2.2.2.2.  I didn't think it even did automatic firmware updates.  About a week ago, the router went back to it's old ways, where it becomes unresponsive several times a day, and the only fix is to restart the router.  I suspect that this is when the new firmware version got updated.

I didn't even think that automatic firmware updates were a thing with this router, so I don't remember if there was a setting for this, or what it was when I was on the older firmware.

Just yesterday, I did a factory reset, and set up all the IP reservations again... I hope this fixes the issue, but I want to know if there is a way to just block automatic firmware updates, and this new firmware version getting automatically updated appears to be what caused my router to again start hanging several times per day.
