Possible, for example if the router is blocking something.

 

Check what is running on the box, what it is talking to, and what it is saying.

 

Use tools like "ps", "netstat" and "tcpdump" (needs to be installed from the feed).

Thanks for tcpdump.
My Home Assistant makes http requests to Zgemma. I do not know why but I disabled openwebif and it works now. I have to figure out why HA is trying to communicate with box

Router 1000Mbit and box 100 Mbit? Packet collisions?

not sure, i limited bandwith and it did not help.

Shouldn't make any difference if there is no traffic. Even 10Mbps half-duplex should be causing freezes, something is blocking the CPU.

What runs on the box that requires a network connection?

 

Any weird connections when you issue the command

netstat -t

on the commandline?

Well, it look to me that you have a ‘visitor’ from outside your network. Most likely you have forwarded a port to access your box from outside your network… IF you need to access your box from the outside use a VPN instead…

it turns out that it is something with my router asus rt-ax55, when I plug WAN directly into the box then it works fine. but when the router is between WAN and box then freezing appears.

anyway i do not understand why...
