I bought a DeskJet 3755 and I can't get it to connect to my WiFi. Obviously, HP Easy Start won't be able to connect it if it's not on the WiFi, and when I press the WiFi button on the printer all that happens is the blue WiFi light blinks and it never finds the WiFi network. Any ideas on how to make this happen? Unlike other HP printers, this one doesn't have an informative display panel that shows me how to connect to an existing network.
