Re: installation

If your internet or cable light is blinking then you probably have a cabling issue.These modems are designed to be ran with an RG6 home-run line to the cable box outside.You cannot have any splitters in between.A home-run is a cable that runs to the service box on the outside without any splitters.

Sounds like a problem with your cable connection. Check your coaxial cable, and the splitter from where the cable enters your home. The tech will use a signal meter to measure the quality of your cable, and then replace the wiring if necessary.

Cablevision wire goes to the modem. It should be the first device on the cablevision wire. If you need a splitter, it needs to be a GOOD one, connected DIRECTLY to the incoming Cablevision wire as it enters the house. Use good copper wire.

Order of events:
Connect the cablevision wire to the Modem.
Connect the Ethernet cable to the computer and the modem.
Power on the cable modem.
Right click the network Icon near the clock and click 'repair' (Or reboot the computer)
Apply for and get an account for cable Internet from your Cable company.
After a few days, cable Internet should work.

Trying to install router for wireless

If that's hooked to comcast you can only have one computer hooked up to it, and no modems as they block mac address. If you are a Comcast customer there is a workaround. Turn on your wife's wireless if she hasit, if not get her a wireless card USB is easiest. Turn on sharing on that wireless card and you will be able to access the internet through your wifes computer, and not run afoul of your Comcast agreement. Or request an upgrade to a wireless router from Comcast but your rent goes from $3.00 per month to $10.00!

The modem will not connect to the internet via USB (only ethernet

It sounds like you need to download a driver for the modem's usb connectivity. You can do this by "googleing" the make & model from the manufacturer's website.

Inability to connect to Internet

The easiest solution would be to use an ethernet connection. A second problem is probably on most cable modems you can either use a USB connection OR an ethernet connection you cannoot use both at the same time.
