Welcome to the HP English Community --

When the wireless light on the printer flashes on and off, it is a symptom of a lost connection.

The Wireless connection is lost between the printer and your network -- or, if using Wi-Fi Direct, your computer / tablet / phone.

Start here:

Solution depends on the reason the printer cannot make -- or maintain -- the connection.

Reminder:  This printer supports Wireless on the 2.4GHz frequency only.

Connectivity, standard

1 Hi-Speed USB 2.0 (device); 1 Wi-Fi 802.11b/g/n
