About Wired (Ethernet) Connections 
Ethernet is the most commonly used wired network protocol, with data transfer rates 
of 10 Mbps, 100 Mbps, or higher. The base station’s auto-negotiation feature 
automatically determines the rate of your network connections and uses the fastest 
speed available. 
You will probably use Ethernet cables to connect some devices in your network, for 
example to connect your base station to a modem and to one or more computers. 
Each device that makes a wired connection to your base station must have an 
Ethernet adapter, which provides an Ethernet port. A modem and up to four other 
Ethernet devices can connect to the base station. By using hubs or switches, you can 
connect more Ethernet devices to your base station.  
Ethernet Cables 
An Ethernet cable resembles a phone cord, but has wider connectors at each end. You 
can distinguish Ethernet cable from phone cable by the larger connector size and, 
often, by the number of gold pins (or contacts) visible in the connector. Ethernet 
connectors (RJ-45) commonly contain eight contacts, whereas phone connectors  
(RJ-11) contain either two or four, as shown in the following illustration.

RJ-11 Telephone

Note   There are two types of Ethernet cable, “straight-through” and “crossover”. You can 
use either type when you connect devices to the Microsoft base station. For other Ethernet 
connections that you establish on your network, a specific type of Ethernet cable might be 
required. For more information about the types of Ethernet cable, see the Broadband 
Network Utility Help.
