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

1From your computer system tray, click the wireless icon that corresponds to the software managing your wireless network adapter.

2Check 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:

> 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).
