Intermittent internet outage help
I am experiencing occasional internet outages that last maybe 15-20 seconds on my network. It seems to happen randomly once every few of hours, maybe 3-5 times most days, but not everyday. It's long enough to kick me off of online games like MTG Arena and Overwatch and interrupts my Twitch stream but it comes back quickly. This has been going on for a few months. It's been annoying, but it isn't super often.
The network is pretty simple:
- Brand new Netgear modem. (It happened on two modems)
- Netgate PFSense firewall 5100
- "Big" 16 port switch, small 8 port switch for a few more devices (I've replaced both with equally "dumb" switches)
- Google dot wifi AP
- 1.1.1.1 and 1.0.0.1 DNS servers on the Netgate.
I suspected my local devices but they all drop at the same time. I suspected my switches: I have swapped them all to spares and the issue continues.
I look at the pfSense Status/System Logs/System/General and it never shows errors during the blips. I look at the Netgear Modem and it doesn't have any errors in the event log during the outage. I am sure there is more I can ask the devices but I don't know what.
My only clue/suspicion is that this started happening after adding a HAProxy reverse proxy for a Jellyfin. ...but I've removed the DDNS entry and the outages continue. I'm not sure how I can rule out the ISP being flaky.
What other logs can I look at? Can I run any scripts somewhere to help diagnose? Sorry if there is too much or too little relevant info.
Thanks in advance for any suggestions!
