Wireless connectivity checklist
Verify that the network cable is not connected.
Verify that the printer and the wireless router are turned on and have power. Also make sure that the
wireless radio in the printer is turned on.
Verify that the service set identier (SSID) is correct. Print a conguration page to determine the SSID. If you
are not sure the SSID is correct, run the wireless setup again.
With secured networks, verify that the security information is correct. If the security information is
incorrect, run the wireless setup again.
If the wireless network is working correctly, try accessing other computers on the wireless network. If the
network has Internet access, try connecting to the Internet over a wireless connection.
Verify that the encryption method (AES or TKIP) is the same for the printer as it is for the wireless access
point (on networks using WPA security).
Verify that the printer is within the range of the wireless network. For most networks, the printer must be
within 30 m (100 ft) of the wireless access point (wireless router).
Verify that obstacles do not block the wireless signal. Remove any large metal objects between the access
point and the printer. Make sure poles, walls, or support columns containing metal or concrete do not
separate the printer and wireless access point.
