Wireless connectivity checklist
Review the following information to check wireless connectivity.
● 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 identifier (SSID) is correct. Print a configuration 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).
