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 Network, Routing, Firewall, and Basics 54 Mbps Wireless Router WGR614v7 Reference ManualB-16 AprilWhat You Need To Use a Router with a Broadband Modem Computer Network Configuration RequirementsAppendix C Preparing Your Network Cabling and Computer HardwareInternet Configuration Requirements Where Do I Get the Internet Configuration Parameters?Preparing Your Computers for TCP/IP Networking Record Your Internet Connection InformationConfiguring Windows 95, 98, and Me for TCP/IP Networking Install or Verify Windows Networking ComponentsIf you need to install a new adapter, follow these steps Choose Settings, and then Control Panel Locate your Network Neighborhood iconClient for Microsoft Network exists Ethernet adapter is present Verify the following settings as shown54 Mbps Wireless Router WGR614v7 Reference Manual TCP/IP is presentSelecting Windows’ Internet Access Method Verifying TCP/IP PropertiesConfiguring Windows NT4, 2000 or XP for IP Networking Install or Verify Windows Networking ComponentsLocate your Network Neighborhood icon DHCP Configuration of TCP/IP in Windows XP, 2000, or NT4DHCP Configuration of TCP/IP in Windows XP Administrator logon access rights are needed to use this window DHCP Configuration of TCP/IP in Windows Right click on Local Area Connection and select Properties The Local Area Connection Properties dialog box appearsObtain an IP address automatically is selected Obtain DNS server address automatically is selectedDHCP Configuration of TCP/IP in Windows NT4 Preparing Your Network 54 Mbps Wireless Router WGR614v7 Reference ManualC-16 AprilVerifying TCP/IP Properties for Windows XP, 2000, and NT4 The TCP/IP Properties dialog box now displaysMacOS Configuring the Macintosh for TCP/IP NetworkingMacOS 8.6 or Verifying TCP/IP Properties for Macintosh Computers Verifying the Readiness of Your Internet Account Are Login Protocols Used?What Is Your Configuration Information?

What are the Key Features of WPA and WPA2 Security? How Does WPA Compare to WPA2 IEEE 802.11i?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 Login Authentication Wireless LANWired Network with Optional 802.1x Port Based Network Access Control Figure 4-3 WPA/WPA2 Overview2.
