StephenleCan I update version online? Can you show me how to update to the 1.0.6.12 firmware more detail?
It's specific to the family of modems cvakulskas is using, the Motorola SB6120/6121/6141. Yours is a 6180, and already has the latest for that model, SB6180-3.5.8.4-GA-00-507-NOSH, or 3.5.8.4 for short. (Firmware versions may not seem to have any sense to them, given the plethora of manufacturers, models, and technicians' attempts to abbreviate them.

You can check your firmware version at http://192.168.100.1 and for a Motorola modem it's under the "help" tab. It's updated automatically by the system.
