Let’s get started
If you don’t have cable Internet service, please order that from your cable
service provider. Comcast Xfinity customers should also order phone service
if they want to use the MT7711 phone lines. This phone capability works for
Xfinity, but not for most other cable services since they use a different
version of PacketCable to deliver their phone service.
Now connect your MT7711 as shown on the following page.
Connecting to a Coax Cable
Please see the connection photo on the next panel. You connect
your MT7711 to a “live” coax cable. Sometimes a cable will already
be available. Sometimes there’s a coax wall jack available, and you
connect to the jack with a coax cable. Your MT7711 can also share a
coax cable attached to a TV by using a coax splitter. Please note that
a badly chosen splitter reduces a cable modem's speed; so if you
need to use a splitter, use a 2-way splitter whose top frequency is
1,000 MHz or higher.
