I’ve been dealing with this bizarre networking issue for years now. It’s impossible to google. On the left is my wifi router. On the right is my local Comcast gateway. Pings are randomly dropping. Internet service is disrupted, as you would expect. Router says it’s disconnected from the internet.
Here’s the weird part. Connections that are established keep working. Zoom calls keep working. WoW keeps working. Discord voice keeps working. NEW connections will fail – probably due to DNS. But some existing connections will also fail. Web pages become intermittent. I was just in a Slack conversation with someone when the problem started and my Slack was disconnected.
Rebooting the router OR the modem will fix it. I believe it will also fix itself after an unknown number of minutes / hours. It happens 1-3 times per week, so it’s pretty fucking annoying.
I asked my network guy at work about it and I don’t think he understood me. He mumbled something about IPsec confusing the Comcast modems. We rarely have VPNs running in my house. I cheat and do my work through Chrome Remote Desktop. One time, however, when the problem was occurring my wife was on a Zoom meeting and the second she got off the problem ceased. This was a one-time thing, however. She was on Zoom when this event began and it didn’t go away when she ended it.
The router is fully up to date.
Here it is after I rebooted the router -
E - I have my router set to reboot every day at 4:02am. Not that it helps.
