How do I resolve wireless connection problems on the HP Officejet Pro 8600 Plus?

Follow these steps in order: verify the wireless light is on by enabling wireless under Setup > Network; confirm your computer is connected to the correct network; restart the router and printer (router first, then printer); and run the Wireless Network Test from Setup > Network > Print Wireless Network Test. If the signal is weak, try moving the printer closer to the wireless router and keep it away from large metal objects and microwaves that can disrupt signals. (Pages 23-24)
