Hi, I had set-up my HP Deskjet 3637 on my wifi network earlier this year, now I have changed my internet service provider and have a new Wifi network. How can I update the Wifi on this printer. I tried the set-up again and did not work, the printer was not getting detected. Tried using USB cable a I am trying to connect my HP Deskjet 3760 printer to a new WiFi connection after moving into a new flat. It’s a password protected network that I need to register a device to using the MAC address, which I have added my printer already. I can’t figure out how to connect to the WiFi at all. It doesn’t have a display, just some buttons. Next reset the wireless settings by pressing and holding both the WiFi and Cancel buttons for 3 seconds till the power light blinks, then turn the printer off and back on. Ensure the wireless light still blinks, else press the WiFi button once and it should blink, then follow HP Smart again to reconnect your printer. Shlomi. 25jO.
