Wireless connectivity checklist
●
Verify that the network cable is not connected.
●
Verify that the product and the wireless router are turned on and have power. Also make sure that the
wireless radio in the product 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 product as it is for the wireless
access point (on networks using WPA security).
●
Verify that the product is within the range of the wireless network. For most networks, the product 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 product. Make sure poles, walls, or support columns containing metal or concrete
do not separate the product and wireless access point.
