USG FLEX 100H crashes every 3/4 days and stop internet in fits and starts

Gru_Ma · October 21

Hello
I have all zyxel devices in various companies and I'm regretting it.Now flex 100H internet works intermittently. After 4/5 days it completely crashes. Even when it's not crashing it's practically impossible to navigate.I don't see any ddos attacks in progress or other problems except exceeding the maximum session per host (1000). I lowered it to 100. But nothing works.

There are the last firmware.

We must change it? There are some solutions?

Hi @Gru_Ma

Could you please confirm the firmware version you're currently using? We recently released the latest firmware, uOS1.30. If you haven't already, please upgrade to this version and see if it helps resolve the issue.

In the meantime, we suggest connecting to the console port of the USG FLEX 100H to gather more diagnostic information. You can follow the steps in this guide to troubleshoot freezing and instability issues:

Once you've collected the info and logs, please send them to us via private message, and we'll assist you further with the investigation.

Hello

the last firmware was installed. After the reboot the system is up but go really slow. Internet go slow when works.

I have moved most of pc on another gateway on the same lan and works.

I'll connect the console on the next crash.
