If you get good speed when a computer’s plugged into the
modem, you may have a router problem.
Some video streaming services get bottlenecked, especially at
busy times like after dinner. See whether you have the speed
problem at less busy times.
Try connecting your cable modem nearer to where the coaxial
cable comes into your home. This lets you see whether your
home’s cabling is a problem.
If you’re using a splitter with your cable modem, try the cable
modem without the splitter to see if that helps. If it does, you
may need to get a better splitter, one with a top frequency of
at least 1000 MHz.
Make sure your computer’s or router’s LAN port supports
gigabit rates (1000BT or GE). You will need this to match
service speeds of 100 Mbps or greater.
What if I'm told that my cable modem isn't approved for
my cable modem service?
That’s probably not true. Leading cable service providers have
a list of certified cable modems, and you can check the list for
your service provider. You can also find information about
certifications at www.motorolanetwork.com/services
