I recently acquired fiber connection at home, but I faced an issue, every 10 minutes, the connection kinda stop and then restart. Which cause websites or any software that require internet connection to crash/wait during around 1 minute.
This is annoying. So I started investigating.
Step 1: ping command
I ran a simple ping command for few entires days:
ping -t www.google.com
The result was clear: I never saw any problem or increasing ping:
So at first as I didn't have any clue, I started asking myself if I was crazy or not, if thoses application really stuck for few secondes every 10 minutes.
They did and they still do.
Step 2: Using Ethernet cables
Then as I was using a Power-line communication (PLC), for a computer, and WiFi for an other one. I unpluged the PLC, desactivated the WiFi and bought a 25-meter ethernet cable running through the entire house in order to plug my computer exclusively using cables.
Nothing changed: stable ping but still some Jitter and connection that I could see but not identify.
Step 3: pingplotter
Then I dowloaded and installed pingplotter. Which graphs latency and packet loss between a computer and a target website or server.
The result obtained in the following:
As you can see on the image above, the ping increase slitly, but not enough to make a websote or a software disconnect itself.
The interesting part is the Jitter (ms) that appear at 6-minutes of intervals.
I'm sure this is the cause of all my stuggles.
Do you have any ideas how to fix/avoid it ? Or even what it is ? What's causing this ?
Thanks in advance !
FAQ
What do you mean by "Jitter" ?

What do you mean by stop and restart? Does the Ethernet connection drop? Can you still ping Google when this happens? – Ron Trunk – 2019-04-28T20:48:15.200
Do you see any jitter if you ping the ISP gateway? – Ron Trunk – 2019-04-28T20:53:01.283
@RonTrunk The Ethernet connection is still connected and the ping to google perfectly works when this happens (see Step 1). I haven't tried to ping the ISP gateway i'll check this monday evening and give you some feedback. – Ced – 2019-04-29T00:00:13.390
@RonTrunk I did tests as promised. I couldn't find how to ping the ISP gateway, so I pinged both my Public IPv4 address (which I suppose is also the ISP?) and my local IP, none of them has any jitter while www.google.com does. If I can provide any more information feel free to ask me, this problem is very important to me and I feel like my post don't have enough attention. – Ced – 2019-04-29T21:25:43.480
There’s very little you can do about the jitter. The Internet gives no guarantees regarding performance. 1 minute interruptions, however, should be taken up with your ISP. – Ron Trunk – 2019-04-30T00:12:40.603
The problem is that ISP don't really care about it, do you think leaving this one and taking another ISP could solve the issue ? Also can it depend on the router the ISP provided ? – Ced – 2019-04-30T06:50:53.753
@RonTrunk Also I noticed that I am able to produce high Jitter easily if I update or download any software. If this may help – Ced – 2019-04-30T19:27:30.280
