Issue
Receiver is configured for SWiM
but cannot detect SWiM.
(Associated with 771A OSD).
Your receiver is configured to
work with a home network, but
the network was not detected.
Please check the network cabling
and equipment. Select "Test
Again" to see if this has solved
the issue. Communication
problem between receiver and
home network or router.
Your receiver detects the
presence of a home network,
however it cannot access the
Internet. If your network does
have a broadband connection
present, this may be due to the
receiver not obtaining a DNS
entry during DHCP negotiation
with your home network.
The receiver is connected to the
Internet, but no dial tone is
detected.
The receiver was previously
configured for a network, but the
Internet and the dial tone is not
detected. A 70 or 71 will also be
present.
Dish alignment test not run.
Resolution / Troubleshooting
Look for a faulty SWiM power inserter, a power
inserter on a switched electrical outlet or anything
inline that will not pass or attenuates the 2.3 MHz
control channel. These can often be non-DIRECTV
approved splitters added by the customer or long
cable runs. These issues can often be intermittent. An
accidentally attached b-band converter can also result
in a loss of SWiM communications.
Terms: Home network = Customer‟s router or ISP
modem. DNS = Domain Name System. It translates
domain names into an IP address that can be used by
the DIRECTV receiver or computer. DHCP = Dynamic
Host Configuration Protocol. It gets parameters
needed to operate in an IP network. Restore Network
Defaults. It doesn't restore entire receiver settings -
only resets the network settings for Internet
communication: After receiver resets to network
defaults: Select "Connect Now." Select "Test
Connection" to make sure your receiver can connect
to your network and the Internet.
This is a basic dial tone test. Check for a poor phone
line connector and that the phone line is plugged into
the correct jack. Test the phone line on a spare non-
powered phone. Access the hidden menu using the
menu and right arrow and run the modem test. Note
that if a diagnostic code 72 is displayed, this should
only impact caller ID since PPV details are reported
through the Internet.
Resend authorizations and retest.
