How can I improve wireless signal strength?

A common reason wireless printers fail to communicate over a network is poor wireless signal quality. If the signal is too weak, too distorted, or blocked by an object, then it cannot carry information between the access point (wireless router) and the printer.

If you think signal strength is a problem between your access point and the printer, then try one or more of the following:

Notes:

•The solutions below are for infrastructure networks. If you are using an ad hoc network, then adjust the computer when the solution suggests adjusting the access point.

•Ad hoc networks have a much shorter range than infrastructure networks. Try moving the printer closer to the computer if they seem to have trouble communicating.

CHECK THE WIRELESS SIGNAL QUALITY

To determine if the printer is receiving a strong signal from the access point, print a network setup page. The Quality field indicates the relative strength of the wireless signal the printer is receiving. Drops in signal strength can be intermittent, however, and although the signal quality appears high, it may drop during certain conditions. If the signal quality is listed as good or excellent, then another factor is causing the problem.

For more information on printing a network setup page, see the User's Guide.

MOVE THE PRINTER CLOSER TO THE ACCESS POINT

If the printer is too far away from the access point, then it will not be able to communicate with other devices on the network. For most indoor wireless networks, the maximum distance between the access point and the printer is approximately 100 feet (30 meters). This distance could be longer or shorter, depending upon the layout of the network and the limitations of the access point.

REMOVE OBSTACLES BETWEEN THE ACCESS POINT AND THE PRINTER

The wireless signal from your access point will pass through most objects. Most walls, floors, furniture, and other objects will not block the wireless signal. However, there are materials that are too dense for the signal to pass through, such as objects containing metal and concrete. Arrange your printer and access point so that the signal is not blocked by such objects.

REMOVE SOURCES OF INTERFERENCE

Other types of radio frequencies can cause problems with the wireless signal on your network, resulting to printing issues that seem to come and go.

•Turn off potential sources of interference where possible.

•Avoid using microwave ovens, cordless phones (but not cellular phones), baby monitors, almost any kitchen appliance, wireless surveillance equipment, or any appliance containing a motor when printing over your wireless network.

•If another wireless network is operating in the vicinity, then change the wireless channel on the access point.

•Do not place your access point on a printer or other electronic device. Such devices can also interfere with the wireless signal.
