it might take some time being a freeware driver solution
Note: it will find all of your outdated drivers

This will automatically search for and find the correct driver you will have to update every driver individually once you update you might be asked whether you want to restart or make a system restore point.

Click no to both of these then continue updating each driver free then restart once all of the drivers have been updated.

on the home page you should see a search tab just type in what you are looking for
IE: Modem name wireless or internet drivers.
Place a tick in either windows software or all software box.
You might have to try a few times to get it right.

You should be able to just unplug the usb and connect the Ethernet cable to the netgear router without any problems.
Thanks,

You need to register your modem with your cable provider. They will need the MAC address which is on the side or Bottom of the unit.

Connecting the device, see the "Quick Reference Guide":

Motorola support page for cable modems

hi richard there is search on the internat dorry i cant rmber the site

Hi, Create a temporary folder say C:\Motorola and put all your unzipped Motorola USB drivers. Install your Cable Modem. If and when Windows asked where the drivers may be located, point to the C:\Motorola. If your modem has already been installed and operational and you simply want to update its current drivers > go to Device Manager and right click on your modem to update, likewise point to the C:\Motorola. Hope this be of some help/idea. Post back how things are or should you need further information. Good luck and kind regards.
