Lost internet connection for a few minutes... what could have caused it?

Open | Networking

I lost internet connection in the middle of a stream for unknown reason. Is my router or modem to blame, or did Xfinity causes the issue?

Both router and modem remained accessible during the internet issue.

Router: ASUS RT-AC1900P Modem: Motorola MB7621 Cable Modem

If you have had no issues previously, safe bet would be your ISP. You can reach out to them and ask if there was a loss of connection to your device in a specific time window

Odds are it was just your ISP being down for a few minutes. Happens me to a few times a week, usually at night.

BTW Your router might be vulnerable to an active exploit, check: https://www.asus.com/content/ASUS-Product-Security-Advisory/ Look for Cyclops Blink on the page.
