Each LOCAL Ethernet port will automatically sense whether the Ethernet cable plugged into the port should have a normal connection e.g. connecting to a computer or an uplink connection e.g. connecting to a router, switch, or hub. That port will then configure itself to the correct configuration. This feature also eliminates the need to worry about crossover cables, as Auto UplinkTM will accommodate either type of cable to make the right connection April 54 Mbps Wireless Router WGR614v7 Reference ManualB-16 Network, Routing, Firewall, and BasicsCabling and Computer Hardware Computer Network Configuration RequirementsAppendix C Preparing Your Network What You Need To Use a Router with a Broadband ModemWhere Do I Get the Internet Configuration Parameters?

How Does WPA Compare to WPA2 IEEE 802.11i? What are the Key Features of WPA and WPA2 Security?The primary information conveyed in the Beacon frames is the authentication method and the cipher suite. Possible authentication methods include 802.1X and Pre-shared key. Pre-shared key is an authentication method that uses a statically configured pass phrase on both the stations and the access point. This obviates the need for an authentication server, which in many home and small office environments will not be available nor desirable. Possible cipher suites include WEP, TKIP, and AES Advanced Encryption Standard. We talk more about TKIP and AES when addressing data privacy below Figure 4-3 WPA/WPA2 Overview Wireless LANWired Network with Optional 802.1x Port Based Network Access Control Login Authentication2.
