6.1.8 Link Information
Use the Link Info screen to find out more information on the connection between two Powerline adapters on your Powerline network. The link information screen shows the MAC addresses of connected Powerline adapters and statistics on the links.
Figure 27 Link Information
The following table describes the labels in this screen.

LABEL | DESCRIPTION |
Link Characteristics |
|
|
|
Source Address | This is the MAC address of the local Powerline adapter. The local |
| Powerline adapter is the one connected directly to your |
| computer. A MAC address is a number that uniquely identifies a |
| device in a network. |
|
|
Destination Address | This is the MAC address of a remote Powerline adapter. A |
| remote Powerline adapter is in the same Powerline network as |
| the local Powerline adapter but is not connected directly to your |
| computer. |

Statistics |
|
|
|
Avg. | In Powerline networks data is sent in physical blocks (PB). This |
Rate | field shows the average percentage of errors in the physical |
| blocks received by the destination device from your source |
| device before the errors are corrected using FEC (Forward Error |
| Correction). Forward Error Correction (FEC) is a system where |
| the sender adds redundant data to its transmissions. It allows |
| the receiver to correct errors without the need of asking the |
| sender to resend the data. |
| A high error rate may not necessarily result in a poor connection |
| as PBs with errors are discarded and the Powerline device |
| adjusts the signal to a frequency level where fewer errors occur. |
