8. Unplug (or reboot) the adapter, plug in another adapter and go back to Step 2.

NOTES:

• Setting the IP: A different IP must be set for each of the adapters that will work on the same

network. Only the PC accessing the configuration page of the adapters must have the same

address range as the adapters;

• Netmask: The netmask can also be changed, for example to a type C (255.255.255.0) if

needed;

• Gateway IP: If the adapter is going to be accessed through a router (for example in a large

office network) the gateway IP needs to be configured. Otherwise, it can be ignored;

• Reboot: The IP change in the adapters will be effective only after a reboot or a power cycle.

COMTREND recommends placing a label on each adapter with the IP address assigned to it

(see warning below).

WARNING: IF YOU CHANGE THE IP AND SUBSEQUENTLY FORGET IT,

YOU WILL NEED THE L2 TOOL TO RESET THE ADAPTER TO ITS

ORIGINAL VALUES.

4.4.2 Setting a Network Identifier

It is strongly recommended to always use a Network Identifier (NID) in your network as this will

protect your network from eavesdropping. It is also necessary to specify the NID if you want to set a

Fixed AP in your network. The same NID will have to be specified in all adapters in the network to

allow communication between them. (See Section

5.1: Changing In-Home AV Node Type for more

information about setting the Fixed AP.)

When changing the NID, please make sure that it is changed in the node(s) connected over the

powerline first. When you have changed the NID in one adapter, that adapter will lose connection to

the other nodes in the network until they also have the same NID. In the example network seen in

Figure 12, the computer is connected to Adapter 1 and communication with Adapter 2 is through the

powerline. In this network, Adapter 1 is the local node and Adapter 2 is the remote node.
