Finding the signal strength
The signal strength tells you how strongly the computer or printer is receiving the wireless signal from the wireless
network. Poor signal quality could affect connectivity during configuration.
Checking computer connectivity
1 From your computer system tray, click the wireless icon that corresponds to the software managing your wireless
network adapter.
2 Check the signal quality.
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:
> Network Setup > Wireless Networking
The signal bars indicating the signal quality appear beside the network name.
To improve signal quality, remove sources of interference and/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.

OVE 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.
