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. ● Verify that the printer is located away from electronic devices that might interfere with the wireless signal. Many devices can interfere with the wireless signal including motors, cordless phones, security system cameras, other wireless networks, and some Bluetooth devices. ● Verify that the print driver is installed on the computer. ● Verify that you have selected the correct printer port. ● Verify that the computer and printer connect to the same wireless network. ● For macOS, verify that the wireless router supports Bonjour. 98 Chapter 6 Solve problems
