Network issues detected - modem activity.
I was watching a movie while my Wi-Fi dropped. The router says it's connected, but the modem only shows one light and it's flashing blue. I've tried resetting it multiple times but haven't done a factory reset yet. Any suggestions? My modem is a Motorola Surfboard SB6121.
It seems your internet service provider isn't working properly. If only a single light is lit and flashing, that might indicate a partial issue.
Outage maps aren't always complete. During overnight periods in the US, maintenance usually occurs, typically between 12 a.m. and 6 a.m. As a network engineer, I perform these tasks because they cause the least disruption to users, mainly due to lower traffic volumes. I’d call your ISP to check the situation.
If you're the downstream or upstream lights (the 2nd and 3rd lights under power, respectively) are not solid, this means the modem is not receiving downstream or upstream connectivity via the Drop Cable feeding your house, or via your household coax wiring. Contact your ISP to go through their standard RF troubleshooting procedures, which may include the below suggestions or may result in booking a technician to come physically check your wiring. In the meantime, you can try moving the modem to a different coax cable outlet in your home (just for testing - it doesn't have to stay there) to determine if just that outlet is bad, or if there may be an outage / issue with the modem itself. Additionally, try swapping coax cables, bypassing coax splitters, and/or checking other equipment provided by your ISP to see if anything else is not fully online.
