USG 20 REBOOTING ISSUE

LorenzoEllegi · September 2021

I've been using my Zywall USG 20 since 2014 without any problem.

In the last few weeks, it keeps rebooting, randomly, every 15 minutes.

I tried to replace the power adapter, but the problem is still there.

I have also updated the firmware to the last release, but the USG 20 still has the same problem.

I'm now trying a USG100 that has the same pro

USG20 is... out of support, since 2016. I am aware because I am using USG20W

Latest firmware version is 3.30 BDR9 WK48 (BDR is for USG20W but there's the equivalent version for USG20), some issues were solved into this latest "laboratory" firmware, which i don't know if it's available also for USG100.

Anyway...

I don't know what kind of power supply you're using, but i had some issues with not so performant switching power adapters. With 1.5 or 2.0A of sustained capacity (2.0 better for USG100) never had any issue.
