This is the original Install disk:

SB5100 Series SURFboard Cable Modem Installation CD ROM Motorola Inc Free...
Just install the original drivers and you should be fine.
If still asks for password,
it is the Administrator user and password for that computer.
Hope it helps!

Open Device Manager and set the wireless adapter Power tab to not turn off to save energy. Or modify Sleep mode to not turn off wireless adapters and USB devices. USB if you use a USB wireless adapter.

Plug in an ethernet cord and type in these numbers in the web address field 192.168.100.1 and enter admin for the username and Motorola for the password and log in.

Otherwise, find the reset button on the router. Press and hold for about 30 seconds to perform factory reset. Then you'll need to reset everything.

You can't see well enough to trace, but you want to perform detailed solder work, after burning out contact already?
Perhaps it is time to purchase another unit...

Have you registered this modem with your cable service?

Press the Standby button to reconnect Internet service. Check the coaxial cable at the modem and wall outlet. Check that the USB or Ethernet cable is attached at the modem and the computer. Try to reset the modem by unplugging the power cord from the modem and wait 1 to 2 minutes.
