Let’s get started

1 Call your cable service provider to order cable Internet

service if you don’t already have it. Mention that your
MB8611 supports DOCSIS 3.1, the fastest cable modem
service standard. Your MB8611 also supports all speeds of
any DOCSIS 3.0 services.

Or, if you already have cable service, you should have
your account number handy in case you need it during
the activation process. You can generally find the
account number on the landing page when you log in to
your cable service provider account. You can also find it
on a recent cable bill.

2 Now connect your MB8611 as shown on the next panel.

Connecting to a coax cable

See the connection photo on the next panel. Connect
your MB8611 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 MB8611 can also share a coax cable attached to a TV
by using a coax splitter. Please note that a badly chosen
splitter may reduce a cable modem's speed or prevent
connection to the network. If you need to use a splitter,
use a two-way splitter whose top frequency is 1,000 MHz
or higher.
