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.

This usually means something is not correct with your incoming signal. If your cable wire into the modem is being run off an amplifier in the wall this could be effecting your service. If the signal is too strong the modem won't be able to communicate for internet.
You could check the incoming wire to see if it is running off an amplifier. If it is you would need to run a new line that is not on the amplifier. I would recommend comcast coming out to check the signal frequency and make the necessary adjustments.

There are many causes of this, but the most common can be solved by going to the CMOS (BIOS) of your computer and disable the power saving on the ethernet, PCI or wathever where you modem is connected.
