Arris Surfboard SB1690 DS light blinking

[AKase]

My modem's DS light is blinking. I've heard that it may be updating its firmware, but that should only take about 10 minutes. It's been 5 days...  It has power, and the cables are good, but won't connect to the internet. I checked with Outages and I am not in an affected area. I tried removing the power cable for 10, 15, 20, 30 seconds, and even had the unit shut off for a few hours - nothing. I did a factory reset - nothing. The DS light has been blinking for 5 days now, and nothing I do changes it. Comcast says it can't reach the modem to restart it - but it isn't a Comcast modem... so?

What can I do to fix this problem? Do I need to purchase a new modem?

You should get a tech out to investigate. A line may be severed somewhere, or there may be an impaired connector / hardware / amplifier.

Good luck !

The blinking light means it has not completed bonding all the channels, or it lost a channel it had bonded.

They stated this: ", but won't connect to the internet."

That's why I recommended a tech visit.
