Networking 121 Checking printer connectivity • From the printer, print a network setup page. In the Wireless section, look for Quality. • View the signal strength from the printer control panel. Navigate to: > Setup > OK > Network Setup > OK > Wireless 802.11 b/g/n > OK > Network Connection Setup > OK > Wireless > OK > View Signal Quality > OK To improve signal quality, remove sources of interference or move wireless devices closer to the access point (wireless router). 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, it cannot carry information between the access point and the printer. 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 you think signal strength is a problem between your access point (wireless router) 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. 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.
