NOTE: After you resolve the problem, follow the instructions in After resolving the problems.
Perform the following steps in the order presented.
Step 1 - Make sure the wireless (802.11) light is turned on
If the blue light is not on, the wireless capabilities might not have been turned on. If you see a Wireless: Off option in the list, touch this option, and then touch On.
Step 2 - Restart components of the wireless network
Turn off the router and the printer, and then turn them back on in this order: router first and then the printer. If you still are unable to connect, turn off the router, printer, and your computer. Sometimes, turning off the power and then turning it back on recovers from a network communication issue.
Step 3 - Run the Wireless Network Test
For wireless networking issues, run the Wireless Network Test.
To print a Wireless Test Report, touch 
(right arrow), touch Setup, touch Network, and then select Print Wireless Network Test. If a problem is detected, the printed test report includes recommendations that might help solve the problem.
TIP: If the Wireless Network Test indicates the signal is weak, try moving the printer closer to the wireless router.
