    I get the internet at various times. The power button is on and the receive sometimes and send and online sometimes. Sometimes when I replug everything it will work for a little while and then disconnect whenever it wants. It never used to do this and it's about 5 years old. Is it worn out?

My modem is connected by my internet is not


You probably disabled the modem. To enable it again, do this:

1. Right click on My Computer.
2. Left click on Manage.
3. Left click on Device Manager in the left column.
4. Open the Modems section in the right column.
5. Right click on the modem and click on 'Enable'.

You should be able to connect again.

Good luck, and please let me know how this works out for you.

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.

It is best to remove the dial up portions because it will help eliminate confusion within your system as to which connection to use. You will be much happier once you get hooked up with broadband....good luck.

Can't connect Motorola sb5100 to a Linksys wrt54g


Make sure that you have the ethernet cord from your modem plugged into the WAN/Internet port on your router. Then unplug the power cord from your cable modem and plug it right back in. After the modem fully comes back online, unplug the power cord on the wireless router and plug it back in. wait 30 - 60 sec and then try and connect.

Most cable companies only allow one active"CPE" at a time for internet access. All this means is when you change what is connected to the cable modem you must always reboot the cable modem to allow access.


Hope this helps. Let me know if it does not work.

Inability to connect to Internet


The easiest solution would be to use an ethernet connection. A second problem is probably on most cable modems you can either use a USB connection OR an ethernet connection you cannoot use both at the same time.

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.
