Notes: • If you change network settings, change them on all the network devices before changing them for the access point. • If you have already changed the wireless network settings on your access point, then you must change the settings on all the other network devices before you can see them on the network. 1 Do one of the following: • In Windows Vista, click . • In Windows XP and earlier, click Start. 2 Click All Programs or Programs, and then select the printer program folder from the list. 3 Click Tools Œ Lexmark Wireless Setup Utility. Note: You may be prompted to connect the printer to the computer again using the installation cable as part of the setup process. 4 Follow the instructions on the computer screen. Wi-Fi indicator light is blinking orange during installation (Macintosh only) When the Wi-Fi indicator light is blinking orange, it indicates that the printer has been set up for wireless networking but cannot connect to the network for which it has been configured. The printer may be unable to join the network because of interference, its distance from the wireless access point (wireless router), or until its settings are changed. These are possible solutions. Try one or more of the following: MAKE SURE THE WIRELESS ACCESS POINT IS ON Check the wireless access point and, if necessary, turn it on. MOVE YOUR WIRELESS ACCESS POINT TO MINIMIZE INTERFERENCE There may be temporary interference from other devices such as microwave ovens or other appliances, cordless phones, baby monitors, and security system cameras. Make sure the wireless access point is not positioned too closely to these devices. TRY ADJUSTING EXTERNAL ANTENNAS Antennas usually work best if they are pointing straight up. You may find that reception improves if you experiment with different angles for the printer and/or wireless access point antennas. MOVE YOUR PRINTER Move the printer closer to the wireless access point. Although the possible distance between devices in 802.11b or 802.11g networks is 300 feet, the effective range for optimal performance is generally 100-150 feet. You can find the signal strength of the network on the network setup page. CHECK SECURITY KEYS If you are using WEP security A valid WEP key is: • Exactly 10 or 26 hexadecimal characters. Hexadecimal characters are A-F, a-f, and 0-9. or • Exactly 5 or 13 ASCII characters. ASCII characters are letters, numbers, and symbols found on a keyboard. If you are using WPA security A valid WPA passphrase is: • From 8 to 63 ASCII characters. ASCII characters in a WPA passphrase are case-sensitive. or • Exactly 64 hexadecimal characters. Hexadecimal characters are A-F, a-f, and 0-9. If your wireless network is not using security, then you will not have a WEP key or WPA passphrase. Using a wireless network with no security is not recommended because it can allow intruders to use your network resources without your consent. CHECK THE MAC ADDRESS If your network uses MAC address filtering, make sure that you include the MAC address of the printer in the MAC address filter list. This will allow the printer to operate on the network. PING THE ACCESS POINT TO MAKE SURE THE NETWORK IS WORKING 1 Check the AirPort status and, if you do not already know it, find the IP address of the wireless access point. In Mac OS X version 10.5 a From the menu bar, click Œ System Preferences. b Click Network. c Click AirPort. Check Status. It should be on. If it is off, click Turn AirPort On. The AirPort status indicator should also be green. Green means the port is active (turned on) and connected. Troubleshooting a printer on a wireless network 20
