Infrastructure mode is the recommended setup method because it has: • Increased network security • Increased reliability • Faster performance • Easier setup Finding the signal strength Wireless devices have built-in antennas that transmit and receive radio signals. The signal strength listed on the printer network setup page indicates how strongly a transmitted signal is being received. Many factors can affect the signal strength. One factor is interference from other wireless devices or other devices such as microwave ovens. Another factor is distance. The farther two wireless devices are from each other, the more likely it is that the communication signal will be weaker. The strength of the signal received by your computer can also affect the connectivity of the printer with the network during configuration. When you installed the wireless adapter in your computer, the adapter software probably placed an icon in your system tray. Try double-clicking this icon, and it will tell you how strongly the computer is receiving the wireless signal from the network. To improve signal quality, remove sources of interference and/or move wireless devices closer to the wireless access point (wireless router). 49

Lexmark recommends setting up a network in infrastructure mode using the installation CD that came with the
printer.
Infrastructure mode is the recommended setup method because it has:
•
Increased network security
•
Increased reliability
•
Faster performance
•
Easier setup
Finding the signal strength
Wireless devices have built-in antennas that transmit and receive radio signals. The signal strength listed on the
printer network setup page indicates how strongly a transmitted signal is being received. Many factors can affect
the signal strength. One factor is interference from other wireless devices or other devices such as microwave ovens.
Another factor is distance. The farther two wireless devices are from each other, the more likely it is that the
communication signal will be weaker.
The strength of the signal received by your computer can also affect the connectivity of the printer with the network
during configuration. When you installed the wireless adapter in your computer, the adapter software probably
placed an icon in your system tray. Try double-clicking this icon, and it will tell you how strongly the computer is
receiving the wireless signal from the network.
To improve signal quality, remove sources of interference and/or move wireless devices closer to the wireless access
point (wireless router).
