What does a blinking blue Wireless light mean on the HP DeskJet Ink Advantage 3700?
A blinking blue Wireless light means the wireless capability is on, but the printer is not yet connected to a wireless network. When the blue light stays on steady, the printer is successfully connected to a wireless network. (Page 1)
