You shouldn't need a key for the modem. However, if you are missing the network key for a wireless modem, there is a reset on the back of the device. (Small hole, usually requires a paperclip). Hold that for 30 seconds or so. It will reset to factory specs - Simply rebuild it from there following the installation CD or directions from the manufacturer's site.

Cable modems do not require drivers in order to operate with the network. They are self contained. If you want to access the modem, in your internet browser, enter 192.168.100.1 in the address bar and you'll be taken to the SB5101 internal web server to see the settings and status. There is nothing in there that can be changed by the user though, it is all set by the ISP.

I forgot what my Motorola SB5101 cable modem's network key is? How do I retrieve it?


You need to connect to the web management interface of the modem

1) Open your browser and enter the address http://192.168.100.1 This is the default IP of the modem.
2) Enter the administrator username and password
3) Once in navigate to the Wirelss button on the left
4) Then you should see a Security tab. CLick on that

The network key that it is using, 1, 2, 3, or 4 will be shown and selected on the left side. .

Hope this helps.

My Motorola Sb5101 modem will not let me access the internet, the send light constantly flashes and i can't attain any internet connection.


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....

You need to disable the UPnP function on the Belkin router. Log into the router(192.168.2.1), and look under System Settings. If you haven't changed the password on the router, the default password is blank, i.e., no password.

No connectivity; constant blinking LED lights "Receive" and "Send"


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.)

Try putting 192.168.100.1 in the address box of a web browser. If the modem is provided by your ISP you might need to call them if that won't work.
