Internet Connection Drops Exactly Every 4 Hours

For quite some time now, I've been experiencing a strange issue where my internet drops out for 3 seconds, every 4 hours. I realize this would sound like it's not a big deal, but every time it happens, my Zoom, Teams, etc. meeting will stall, and take 60-90 seconds to reconnect. The way I've been tracking this is with the "Internet Connection Monitor" extension in Google Chrome.

In this case, the machine that is detecting these outages is a desktop machine connected via Ethernet to switch that is connected to the gateway Eero. Also, the WiFi is disabled on the desktop, so there's only the ethernet connection. Given that, there isn't a reason why it should be losing connectivity.

Eero Model: 3 x Eero Pros (Model B010011) - All Ethernet Connected
Eero Version: 6.6.1-2
Desktop: iMac running MacOS 12.2
ISP Modem: Pace 5268AC
ISP Modem Hardware Version: 260-2173300
ISP Modem Software Version:

Hopefully someone has seen this and has a suggestion of where I can/should look. Thanks!

    If you haven’t already, you should really try to get AT&T to investigate (as painful as that process will be). My money is on it being an issue with your modem, whether it be actually hardware related or buggy firmware.

      cMoo92 Thanks, I did reach out to the ISP, who said that there's nothing on their side, and I should check with my device manufacturer, since I turned off the ISP's built-in WiFi and am using. separate devices. The finger pointing kills me. So far, Eero support is helping me to try and track down the issue.

      Adam Plummer yea, finger pointing is the worst. I’m still pretty convinced that it will turn out to be an ISP issue, but hopefully eero support can give you some evidence to help support your case.

    Since it occurs with such precise regularity, does your ISP's box have a built-in PING capability? If you log in to it and have a continuous PING running from X:25 until X:30 and it shows drops, then that rules out everything downstream of the box -- the Eero, your PC, etc.
