IP Network Issues

Insufficient RF Network Throughput

If the RF light on the BHR is flashing after you connect it to a set-top, use the Connected 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.

As long as the

RF light on the BHR continues to flash, repeat this procedure.

If you make any changes, repeat all tests.
