Cable modem lights stopped working

Try changing the ethernet cable as it is faulty or damaged

turn the computer off and unplug the modem for few seconds (15) then reconect the modem and let it start all the lights
about (20s) then turn the computer on.
if still cannot connect call your ISP

If you have the following lights :
Power light - on
Receive light - flashing
Send light - flashing
Online light - off
PC/Activity - on
Standby - off
Then your Network Access is OFF - modem is successfuly registered but Network Access Control is disabled via DOCSIS configuration file.

Call your internet service provider....

Throw it away or send it to Motorola they get very HOT and this causes failure its common in routers and modems

Best to call up the cable company and go thru the phone prompts...you may just find that they're having trouble in your area...
They can also send a reset signal to your modem too.
Give em a call..

Or you didn't pay your subscription on time and the ISP disabled your cable modem to send user traffic over the cable network. When both Send and Receive lights are blinking that is a visual aid that the modem is working fine, but the ISP disabled its access to the network (unpaid bill, legal issues, etc.)

i guess the above procedure msut work

Online Flashing - Scanning for a network connection.
On - Startup process complete. Modem aqcuired.

No online means no connection to the cable company DHCP server

That online light goes solid when your ISP completes the registration process of your modem. If this process fails, there are only 2 possible reasons. The first is your modem MAC address is not on your account with your ISP, which cannot be your case because it works on a different outlet. The second reason would be what is called ingress on the outlet. Ingress is caused by a bad outlet or more frequently a bad connector. Make sure inside your connector is clean and free of metal shavings. The problem you are describing is actually rare because usually if your having cable issues that cause a registration problem, you don't usually get a send light.

By the way, just because your tv works on that outlet doesn't mean your modem will. Your modem runs off RF frequencies that your TV doesn't come close to.

Your modem is not synching. It could be a number of possibilities, and you're going to have to do some troubleshooting to narrow it down.

• Verify that your AC, Cat 5, & ethernet cables are connected securly
• Verify that your modem is not in "standby" mode
• Power cycle your modem
• Try a different cable outlet
• Call your ISP to make sure your modem is provisioned and your service is set up for cable internet.
