High Jitter

[Depstros]

so every 3days i out of nowhere get 150-200 ms jitter and only restart of the router fixes it..

My configuration:

Router - wifi 4phones= sercom Speedprot plus J932BS001584

switch (router but configured to works as switch) = zyxel VMG1310-B30B

PC1

PC2

PC3

only one pc at use at this point

Jitter measured how? All site/service/servers, or just some? Which devices experience it? Wifi or hard wire?

Since you indicate the router needs to be restarted to fix it, bypass the router by connecting your devices directly to the Sercom (appears to be DSL?) modem, then re-test. If the issue goes away, bam, your Zyxel router is the problem and needs to be replaced with something better. If the issue continues, more testing made be required to determine if it's your ISP, the Sercom DSL modem, or just certain devices on the local network.

I'm merely providing troubleshooting steps you can take to narrow down the issue. Totally up to you if you want to do them or not though.
