Internet disconnects and reconnects exactly 30 or 60 mins every single hour for 1 second

@cvraspir I looks like I might be mistaken, the IP address did stay the same. However, the 1-2 second between disconnect and reconnect does correspond to drop Zoom calls and getting disconnected from online games.

I am wondering if I should just use the IP that was assigned to me as a static IP and run for as long as possible.

Thanks for posting back with that info ! Sounds like there was an issue with their DHCP assigned public IP address lease length / renewal for some reason. Hope things hold up for you. Good luck !

Well, that solution lasted for just a few days. I was just completely disconnected from the internet. It would not let me reconnect until I set the router to use DHCP, which gave me a new IP address. I guess the old IP address I was hanging onto got reallocated to someone else.

I appreciate you keeping us posted on your IP address concerns. To confirm, after it assigned a new IP to you, has it continued to drop every 30/60 minutes or has it remained connected? 

@XfinityStephanieK 

Yes, after I reverted to DHCP, it keeps dropping every 30/60 mins. Here's the router log and some timestamp I took when the disconnect happens:

@bratly Tracert -r and ip or host is what I usually use or you can just use plain tracert to solve to your ISP.   Always gives more info than ping.

@bratly

Every 30 to 60 minutes like clockwork? 

I did a tracert and WinMTR for over an hour, here are the results:

@confuzzeled Yes, every 30 to 60 minutes like clockwork. The IP lease could be 1 or 2 hours, but the disconnect always happen 30 to 60 minutes. The only exception is after I did a manual release/renew, which it disconnected me at 41 minutes. After that disconnect, it reverts back to 30/60 minutes.

Also, the VPN Gateway IP does not seem to be the problem. If I disconnect from the VPN, routerlogin replaces that IP and it also experiences the same packet drop. 

@confuzzeled I did tracing to google.com and other gaming servers with almost identical results.
