  1. I work with these modems almost daily & generally if you’re having issues then you have a home network setup with a router.

    To resolve this issue you should be reading your routers instruction guide but if you’re like most people then you’ve already thrown it away.

    Turn off all computers on your network (not just restart, shut down), then unplug your router, reset your modem.

    Wait for the cable light to go solid. Then, plug in the router and wait a minute while they sync. Turn on your PC’s and you should be able to connect.

    If you’re still not connecting you may want to also check the following:
    Disable firewalls. Check your NIC & make sure it’s flashing in the back of your PC when PC is powered on. Do you have updates waiting to be installed?

  2. I have to restart my computer everytime I want to use the internet. This is a modem or internet problem because my computer works perfectly for other functions. What should I do or try?
    thank you.
