CAX30 Timing Synchronization failure - Loss of Sync

I think the problem was the firmware. I have issues with the wifi connection. When I first got it everything working great. Ally devices connect right away. After overnight the modem automatically updated to newest firmware which is .10.8. The oldest firmware was .10.4. So, how do I know that was firmware because I downgraded and it’s working fine. The modem automatically updated or check for newest firmware from 12-4 AM every time. I return and buy a new one. Same model same everything. Same issue. Working fine for a day then bumped. No wifi connection. Sometime slow connected on my phone but TV won’t able to connected. Called netgear support. They asking me to ask internet provider stop sending firmware update. It’s sound funny because internet provider has nothing to do with it. The manufacturer is the on creating new firmware. When ever the modem got internet it will check for update. I gave up and went back to my old modem and then everything working fine. I’m looking for a different modem different model because this CAX30 having firmware issues that cause so much problems on wifi connection.
Hopefully they will release a new firmware that will fix but I don’t think with in a day.
Return/ replacement or wait for it
Good luck
