Motorola SB5100 Cable Modem Power Lght Flashes

I usually put the modem in Standby when I'm not using it. Went in the other night and the Power Light was Flashing.
All other lights were solid (activity light flickered noe and then).
I know it means it's checking diagnostics... But it kept flashing for like 2 hours. Turned off, disonnected power, plugged back in... It cycled back to Power light flashing. What do I need to do? Get a new modem? This one is 8 years old.
Thanks.

Call your Internet Service Provider.
They can remotely "connect" to the cable-modem, and diagnose it.

Click the factory reset / restore default settings button.
To simply turn i toff and on click reset cable modem below or simply unplug and replug the power cord.

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.

Problems with Motorola Surf SB5100


Have you tried unplugging the modem's power cord for at least a couple of minutes? If that doesn't work, have you called your ISP? The problem could be anything from a billing issue to an outage in your area, to a modem that needs to be replaced. Your internet service provider would be the best place to (try to) find help.

Have you rebooted your modem after hooking it up? Each time you move your connection from your modem, it must be rebooted to issue new information specific to your equipment. Also, make sure you haven't pushed the "Standby" button on the top.

Need to hook up Belkin G wireless router to Motorola SB5120


Plug your cable line into your modem, make sure it's tight, but don't use a tool. Next plug the ethernet line from the modem to your PC ethernet port. Then plug in your power to the modem. Allow your modem to sync. Don't use the USB line at all. Do not even hook it up unless your computer doesn't have a working ethernet line. Don't run the disk either, it will only install the modem driver that is only used if you use USB.

If you have issues connecting after that, you may have to go into your ethernet adapter settings and make sure that it is using DHCP. DSL usually uses a different setting (PPP I think) and you will not be able to connect.

By the way, excellent choice in modems.
