So some background. I've been having internet issues for the last two weeks and I've been trying to figure out why. My ISP swears up and down there is no problem with my connection, I've even had two techs come out and check everything without any issue. Today I decided I'm just gonna trouble shoot it myself (I have a networking background), to hell with the ISP, even though they've told me I cannot go into the rooms in my building etc. I have the keys so I went in. Everything is fine as far as I can tell.
Devices on my network;
-My main PC
-Laptop
-Microsoft Surface
-Samsung TV
-Various apple devices
-Multiple Amazon devices
-Synology Nas
-Intel Nuc (Running OMV 4)
The problem; Every EXACTLY 1 minute 50s the internet on ALL of my devices drops for EXACTLY 30s. Across my entire network. This is a persistent problem and continues this pattern, without fail, even through modem resets.
So I started regular trouble shooting, switched the cables from the modem to switch and all my devices. No change, problem persists. So I decided that maybe the modem (router as well, one box) is having a load issue. So I bought a new router, ASUS AC3100, plugged it in, configured it, etc. Same issue. What a pain.
So I started from scratch. I unplugged everything, reset all the network settings on all my devices. I started connecting 1 device at a time, running a ping to google.ca as I had been to check connection. Low and behold, first device, no ping drops for over an hour. Onto the next device. no ping drops! Cool! So I plug in my PC, no ping drops! Plug in my Nas, no problems! Great, it's working maybe! Plug in my Nuc (the one running OMV) IMMEDIATELY, within seconds, connection drops. BAM GONE. Unplug, connection is back. In, GONE. WTF?
So basically, whenever I plug in my Nuc running OMV 4 my internet connection drops.
I'm not a Linux guy, and as such, I don't even know where to begin to trouble shoot this. My only option would be to format and start over, which I'm trying to avoid.
Any insight and thoughts on this matter would be greatly appreciated.
TL;DR
Plugging my Intel Nuc running OMV 4 into my network completely kills my network and internet connection. No idea why, thoughts?
