Microcuts with Beryl GL-MT1300. Mango works with no problems

Hello!
I have internet microcuts with a Beryl (with and without VPN) while a Mango is working totally fine in the same setup.

My connection is RJ45 cable to Beryl and Beryl as Wifi hotspot. Same when I replace Beryl with Mango.

I updated Beryl firmaware to the latest version and it didn’t fix this issue.

What next steps can I take to solve this problem? Thanks!

Can you post the sections of the System Log (logread) when the problems occur?

You can get it via LuCI → Status → System Log or the SSH logread command.

Sure, here is the log:

Thanks for your help.

The System Log shows Ethernet link down at Tue Mar 29 13:00:50 2022 without any details on the cause.

Can you try a new Ethernet CAT5E (preferably CAT6) cable and plugging into a different port on your Internet modem? The Beryl has 1Gbps Ethernet and the Mango only has 100Mbps Ethernet.
