Linksys One Ready Communications Solution 1 Chapter 4 Chapter 1: Introduction What’s in this User Guide?
Linksys One Ready Communications Solution Chapter 2 Planning Your Wireless Network Network Topology A wireless network is a group of computers, each equipped with one or more wireless adapters. Computers in a wireless network must be configured to share the same radio channel to talk to each other. Several PCs equipped with wireless cards or adapters can communicate with each other to form an ad-hoc network without the use of an access point.
Linksys One Ready Communications Solution 2 Network Layout Chapter The Wireless-G Access Point with Power Over Ethernet and Rangebooster has been designed for use with 802.11g and 802.11b products. The Access Point is compatible with 802.11g and 802.11b adapters, such as the notebook adapters for your laptop computers, PCI adapters for your desktop PCs, and USB adapters for all PCs when you want to enjoy wireless connectivity. These wireless products can also communicate with an 802.11g or 802.
Linksys One Ready Communications Solution Chapter 3 Connecting the Wireless-G Access Point Overview This chapter explains how to place and connect the Access Point. Depending on your application, you might want to set up the device first before mounting the device. Refer to “Chapter 5: Setting Up the Wireless-G Access Point”. Connection 1. Connect your Ethernet network cable to your network router or switch. Then connect the other end of the network cable to the Access Point’s Ethernet port. 2.
Linksys One Ready Communications Solution 3 3. Line up the Access Point so that the wall-mount slots line up with the two screws. 4. Place the wall-mount slots over the screws and slide the Access Point down until the screws fit snugly into the wall-mount slots. 2-15/16" Chapter 5. Now that the hardware installation is complete, proceed to “Chapter 5: Setting up the Wireless-G Access Point,” for directions on how to set up the Access Point.

The WIRELESS LED lights up when the wireless module is active on the Access Point.
Linksys One Ready Communications Solution The Ports The Access Point’s port are located on the back of the device. IMPORTANT: Resetting the Access Point will erase all of your settings (including wireless security, IP address, and SSID) and replace them with the factory defaults. Do not reset the Access Point if you want to retain these settings.
Linksys One Ready Communications Solution Chapter 4 Reset Button There are two ways to reset the Access Point to the factory default configuration. Either press the Reset button, for approximately ten seconds, or restore the defaults using the Access Point's Web-based Utility. Note: If you press the reset button for less than 10 seconds, the device will simply reboot without reseting to the factory default.
Linksys One Ready Communications Solution 4 Antennas and Positions Chapter The Access Point’s antennas are located on the back of the device. The Access Point can be placed on a desktop or wall-mounted. When placed on a desktop, the Access Point can be stacked with other Linksys Business Series products. Antenna The Access Point has two detachable 2dBi omni-directional antennas. Adjust the two antennas so that they form a 90 degree angle for best MIMO range performance.
Linksys One Ready Communications Solution Chapter 5 Setting Up the Wireless-G Access Point Overview The Access Point has been designed to be functional right out of the box with the default settings. However, if you'd like to change these settings, the Access Point can be configured through your web browser with the web-based Utility. This chapter explains how to use the Utility to perform the most basic settings.
Linksys One Ready Communications Solution 5 There are three ways to connect to your Access Point for the first time. Chapter 1. If you have a 48VDC Power Injector (e.g. Linksys WAPPOE), power up your Access Point first, then connect the Injector’s cable to your PC. Configure your PC to have the static IP address on the same subnet as the Access Point’s default IP address (192.168.1.245). 2. If you have a PoE switch (e.g. Linksys SRW224P), connect your Access Point and your PC to the same network.

Linksys One Ready Communications Solution Appendix A Troubleshooting This appendix provides solutions to problems that may occur during the installation and operation of the Wireless-G Access Point with Power Over Ethernet. Read the descriptions below to help solve your problems. If you can't find an answer here, check the Linksys website at www.linksys.com. Frequently Asked Questions Can the Access Point act as my DHCP Server? No.
Linksys One Ready Communications Solution A What IEEE 802.11b features are supported? The product supports the following IEEE 802.11 functions: CSMA/CA plus Acknowledge protocol • Multi-Channel Roaming • Automatic Rate Selection • RTS/CTS feature • Fragmentation • Power Management • What IEEE 802.11g features are supported? • The product supports the following IEEE 802.
Linksys One Ready Communications Solution Appendix A What is Infrastructure? An integrated wireless and wired LAN is called an Infrastructure configuration. Infrastructure is applicable to enterprise scale for wireless access to a central database, or wireless application for mobile workers. What is roaming? Roaming is the ability of a portable computer user to communicate continuously while moving freely throughout an area greater than that covered by a single Access Point.
Linksys One Ready Communications Solution A What is Spread Spectrum? Appendix Spread Spectrum technology is a wideband radio frequency technique developed by the military for use in reliable, secure, mission-critical communications systems. It is designed to trade off bandwidth efficiency for reliability, integrity, and security.
Linksys One Ready Communications Solution Appendix A What is a MAC Address? The Media Access Control (MAC) address is a unique number assigned by the manufacturer to any Ethernet networking device, such as a network adapter, that allows the network to identify it at the hardware level. For all practical purposes, this number is usually permanent.
Linksys One Ready Communications Solution A Does the Access Point function as a firewall? No. The Access Point is only a bridge from wired Ethernet to wireless clients. Appendix I have excellent signal strength, but I cannot see my network. Wireless security, such as WEP or WPA, is probably enabled on the Access Point, but not on your wireless adapter (or vice versa). Verify that the same wireless security settings are being used on all devices in your wireless network.
Linksys One Ready Communications Solution Appendix B Wireless Security Linksys wants to make wireless networking as safe and easy for you as possible. The current generation of Linksys products provide several network security features, but they require specific action on your part for implementation. So, keep the following in mind whenever you are setting up or using your wireless network.
Linksys One Ready Communications Solution B network administrator is the only person who can change network settings. If a hacker gets a hold of the administrator’s password, he, too, can change those settings. So, make it harder for a hacker to get that information. Change the administrator’s password regularly. Appendix SSID. There are several things to keep in mind about the SSID: 1. Disable Broadcast 2. Make it unique 3.
Linksys One Ready Communications Solution Appendix B There are several ways that WEP can be maximized: 1. Use the highest level of encryption possible 2. Change your WEP key regularly IMPORTANT: Always remember that each device in your wireless network MUST use the same encryption method and encryption key or your wireless network will not function properly. WPA. Wi-Fi Protected Access (WPA) is the replacement standard for WEP in Wi-Fi security. Two modes are available: Personal, and Enterprise.
Linksys One Ready Communications Solution B Appendix WPA2 Enterprise. WPA2 used in coordination with a RADIUS server. (This should only be used when a RADIUS server is connected to the AP or other device.) First, enter the RADIUS server’s IP Address and port number, along with a key shared between the device and the server. Then, enter a Group Key Renewal period, which instructs the device how often it should change the encryption keys. WPA2 Mixed.
Linksys One Ready Communications Solution Appendix C Upgrading Firmware The Access Point's firmware is upgraded through the Web-based Utility’s Administration Firmware Upgrade tab. Follow these instructions: 1. Download the firmware upgrade file from the Linksys website, www.linksys.com. 2. Extract the firmware upgrade file on your computer. 3. Open the Access Point’s Web-based Utility. 4. Click the Administration tab. 5. Click the Upgrade Firmware tab. 6.
