That would be a cable issue- either replace the cable that is going into your cable modem or call your cable company to fix problem.

My Motorola sb5101 won't come online how do I troubleshoot this? My cable connection is fine. When the modem boots up the green power light comes on and stays on followed by the receive light and the send...


These modems are very tricky. When this type modem goes into stand by modem that indicates that you do have a connection to your internet service provider. The reason you cant get online is because all internet access is disabled wile the modem is in standby. If you look closely there is a button located on the top of the modem. This is the stand by button. If you hit that button it should take the modem out of stand by mode and reestablish your connection to the internet.

I hope that information above has helped is some way.
If possible please rate this solution.

Modem light is blinking no internet light


hi, there are two ways to assit you on this issue.Either you can call belkin customer care which is a TOLL FREE no. on the product box and get assisted or else proceed with the following basic steps.
1. the product that you have is an obsolette.
2.Before troubleshooting the belkin product. Please connect your computer directly with the modem (without router)on the ethernet(lan) port and check for the solid lights on the modem after turning it on, after that check for internet connectivity, if you can go online, its fine else you need to contact your modem vendor and get fixed.
3. if u can go online, then connect your router isolated port to the modem amd your computer back to the router's lan port(port 1) and check for the solid internet,power,modem,lan lights on the router.
4. if all are solid lights , check you can go online else you can hold the reset button at the rear side of your router for 2 mins if you have a cable modem and then check for connectivity.
5. If you have a dsl connection , then better contact customer care, they assit you very well.

My internet won't work on my new laptop.


First turn off you laptop. Second, go to your comcast cable modem unplug it from the wall and wait about 3mins. Now plug the comcast modem back it and wait for all the lights to come back (will take about 2-3mins). Now plug the yellow ethernet cable into your laptop if its not already and turn your laptop on. You should now have internet.

Also if you using a Comcast Surf Board modem be mindful of the standby button on top of the modem. You can tell your in standby mode if the standby light (bottom light) is amber. If it is press the standby button once to get out of standby mode.

hope that helps

Internet connection


I think your modem needs to be configure by your ISP.
I change my modem here in my house with other brand and did'nt work, so i put the original modem i used and it works again..

Cable light off


Your cable signal is low.If you have any splitters remove them.there is only one single cable that should go to the modem out to the box on the house then inside the box the cable for the modem should be on a 2 way splitter, the input is from the cable service, one output goes directly to the modem and the other output usaully goes to another splitter that runs the rest of the TVs in the house.basically the modem needs "priority" or first dibs on the bandwidth coming to the house.
