IP Network Issues

Insufficient RF Network Throughput

If the light on the BHR is flashing after you connect it to a set-top, use the Connected
RF
Home Status diagnostic to display the data rate for each MoCA network link (see
Troubleshooting)
The Transmit data rate between each MoCA node is shown on the Link Status page. The
MoCA node can be correlated to the MAC address of each device on the Connected
Home diagnostic.
The Link Status table also shows which MoCA nodes have insufficient throughput
between links (evident by the 'Bw' indicator that precedes the MoCA node ID). Make
note of the MoCA node ID on the Link Status page and the associated MAC address on
the preceding Connected Home page for each device to track insufficient RF Network
Throughput.
The Link Status page displays a table with entries for each MoCA network device:
1. Rows and columns representing each MoCA device on the network are labeled with
the MoCA Node ID.
2. In the Link Status table, asterisks (***) are displayed when there is no link, i.e., the
'To Node' = 'From Node'.
If all displayed Data Rates in the Link Status table are above the required threshold and
the 'Bw' indicator does not appear, the network links to the BHR are normal.
If any displayed Data Rate is below the required threshold, the network may not meet
the throughput requirements. Replace the splitter nearest the ONT with a 2 GHz splitter.
After replacing the splitter, reenter the OSD diagnostics for Link Status. If all Data Rates
are above the required threshold, the network links to the connected BHR are normal. If
any Data Rate remains below the required threshold, continue replacing splitters until all
Data Rates are above the required threshold.
If you have replaced every splitter and any Data Rate remains below the required
threshold, there may be a faulty coaxial cable in one or more branches.
A difference of 10 to 20 Mbps in the To and From rates for the same connection may
indicate an active device, such as an in-line amplifier, in the coaxial cable between the
two devices. See "Bypassing" an Amplifier below.

If you make any changes, repeat all tests.
