printer 3850 won't connect to Wi-Fi

[NoaR]

My printer wont connect to the Wi-Fi. I think it's since I changed the name of the network. 

I tried using the manual but its still not working.

Welcome to HP forums, I see that you are unable to connect the printer to WiFi.

Connect the printer with WPS

1. Locate the WPS button on your router, but do not press it yet.

   If your router does not support WPS, skip to the next step to connect the printer with the HP Smart app.

2. Turn on the printer. If the printer is in sleep mode, press the Cancel button on the control panel.

3. On the printer control panel, press and hold the Wireless button  for at least 3 seconds or until the wireless light starts to flash.

   NOTE: 

   HP Tango printers: Press and hold the Wireless and Power buttons on the back of the printer for 5 seconds. The Edge lighting flashes blue to indicate the printer is in WPS mode.

4. On the router, press and hold the WPS button for 3 to 5 seconds or until it shows that the WPS connection process has started.

   NOTE: 

   The printer stops searching for a WPS connection two minutes after the wireless button is pressed. If you were unable to press the WPS button within that timeframe, attempt these steps again.

   Once the printer connects to the wireless network, the blue Wireless light on the control panel turns on solid.
