Troubleshooting Tips
What if I can’t make an Internet connection right after
installation?
• First turn your MT7711 off for at least 8 seconds, then on, to see if that fixes
the problem.
• Check the connections you’ve made to your MT7711. Power and coax
connections are required, and up to 4 Ethernet connections are optional.
Are those connections good? Be sure that the coax cable connection
finger-tight, possibly using the coax wrench. Do not over-tighten.
• Check that the MT7711’s power supply is plugged into a live outlet, and that
the Ethernet cable (if used) is connected securely.
• Make sure that your coax cable is live. You can check that by using it with a
TV.
• Check that you provided the correct setup information to your cable service
provider.
• Contact your cable service provider to make sure they’ve turned on your
Internet service.
What if I can’t make or receive phone calls right after
installation?
• Make sure that you’ve ordered Comcast Xfinity phone service.
• Make sure that the Tel1 light is ON (lit solidly). It may take several minutes
after power-up before voice service is established. Note also that it may take
several days to activate voice service for the first time.
• If the Tel1 light never turns on, turn your MT7711 off for at least 8 seconds,
then on. Wait up to 10 minutes to see if that fixes the problem.
• If the Tel1 light still isn’t ON, call your service provider.
