Wifi down - modem flashing

Recommended Posts

Posted · Original PosterOP

So i was streaming a movie when my wifi went down. My router still shows that its connected to the internet, but my modem is only showing one light and its flashing blue. I've tried several resets but havent done a factory reset yet. Any advice?

The modem is a motorola surfboard sb6121

Sounds like your ISP is down then if only one light is on and flashing.

Outage Maps dont always tell the full story. Overnight hours, assuming you're in the US is when maintenance activities happen, generally from 12a-6a. I am a network engineer and this is when we do our maintenance as its the least impacting to the end user typically since its the least volume of traffic time. I would give your ISP a call and inquire.

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.

Good advice

Just thought I'd give an update, internet was back when i woke up this morning. As @Skiiwee29said, it was most likely just maintenance.

 

Thanks everyone
