let's see-on printer control panel, you've pressed the right arrow, then "network" then "wireless" then "wireless setup wizard" then OK,
and the wireless capability has been turned on, yes? (I didn't know you could turn it off) -either press the wireless button, or press setup on the printer's control panel, then wireless menu, then touch "On". A blue light should be lit up.
Failing that, restart the wireless components-turn off router, then printer, then turn on router and then turn on printer. dunno what else to suggest
apparently, you can do a wireless test from the printer-right arrow, then network, then wireless, then wireless network test.. .
also see if there are any updates for your printer-there has been a firmware update for this printer from 2012-try that, there is also a software update for 10.10 apparently it adds direct wireless printing...
