Sounds like the driver was erased during the re-install. Use another computer, go to 'motorola.com', then downloads, find your modem and download the driver. I'd give the specific address but its not hard to find.

Yes it can happen after a reinstall.. You will need to go into the computer ie take the back off. Pull the modem out and put it back in in another slot exact to the one you pulled it out of. Try it again it will no doubt read this time.. It can only be done this way if you try to manually install a moderm it will load the standard one NOT your Modem. Goodluck!

2 completely different technologies.
FAX uses phone line (analogue) and router is digital.
It's one or the other.
Plugging what is essentially a modem into another modem was never going to work.
Scan and email is much faster and easier.
Or FAX to FAX through phone line.

Did you do a reset of the Modem ? If not, look at the rear panel, there is a little button. Press it for a few seconds, you should notice the LEDS on the from panel switch off or flash. Release the Reset button and wait for the LEDS to light up normally again.

You may need to call vizio to reactivate the modem, but it should correct your WiFi problem.

Let me know if this helped.
