Use reset button at the back.

if it is purchased - got to contact ISP to register the MAC address.

if it is provided by the ISP - have it replaced.

After connecting modem to pc, the link light in modem was orange, the others were all green, of course, pc can not surf internet. Try to restart and change modem location, issue persists


Hi,

Good day.You can do the following to make your connection work.

1. You need to make sure that the cable connection between your modem and wall outlet is tight.
2. Ethernet cable should be detected when plugged in to your pc ( usually a pop up on your screen will tell that)
3. Link light means there's a conenction between your pc and cable modem.
4. You might need to check if the online light or cable light on the modem is on to make sure that your modem is getting a signal from your cable internet provider. If its off you need to contact your internet provider because there could be an issue or possible outage on your line.
5. You can also try to restart your computer once its connected to the modem to refresh the ip address of your pc.
6 You can also contact the tech support number for your internet provider for them to diagnose the issue.

Hope this information will help resolve you're problem. Have a great day and thanks for using Fixya.

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.

My modem keeps going to standby mode


That is usually a problem with signal levels or the modem isn't set properlly. I don't know who your provider is but you should get hold of them and get them to fix it. They should send a tech out to check your signal. While they can check the modem remotely it does not provide them with the same information that a onsite check does. There is nothing you can check or change as a end user.

This can be signal levels, or signal quality (noise), or bad cableing and so on.

Cannot go to internet


As stated on your previous post asking this question:

"If the "Online" indicator is not on, then the modem does not have an internet connection. The only thing you can do is unplug the modem for 15 seconds and plug it back in. Wait 30 seconds for it to cycle and the lights should all come back...if the "Online" light still does not go on, then you need to contact your internet service provider."

There is really nothing else you can do!

Cable modem connection problem


Hi, First of all that particular modem is an End of Life modem (meaning it is no longer recieving updated firmware). But that still does not neccesarily mean that its your modem what you need to do when your modem cuts out is to note the leds on the front of your modem. If the modem gets stuck on either the 2nd light from the top or the third light then it is definitely a cable problem. Contact your cable co and tell the tech what lights were stuck blinking while you could not get online and he will know what that means. If you need some more help let me know, because I can explain more. good luck
