Cannot connect to new wi-fi network

[LamarrT]

HP Color LaserJet m251nw moved to new location. Sees the new wi-fi network in setup Wizard, but failed connection message after entering verified network password. A Color Laserjet MFP 277dw is next to the 251 and is on the network.

Printer connected to the old network without issue and was used for wireless printing regularly.

Hi @LamarrT,

Welcome to the HP Support Community

I understand you are facing a connectivity issue with your HP LaserJet Pro 200 color Printer M251nw. Not to worry I will help you to get a resolution to resolve the issue.

To assist you better:

• Is the blue Wi-Fi light blinking on the printer?
• How far is the printer located from the WiFi router?
• Do you have a dual-band router?
• If you have a Dual-band router and both 2.4GHz and 5GHz networks share the same name/SSID, the printer will not be able to connect to the network. In this case, contact your Internet service provider to assign different names to both networks.
   

While you respond to that,  please follow the below steps to resolve the issue.

• With the printer turned on, disconnect the power cord from the rear of the printer and also unplug the power cord from the wall outlet.
• Remove USB cable, if present.
• Wait for 2-3 minutes, press and hold the power button on your printer for about 30 seconds to remove any additional charge.
• Now plug back the power cable straight to a wall outlet without any surge protector or an extension cord (This is important) and then plug back the power cord to the printer.
• Turn on the printer and wait till warm-up period finishes and the printer is idle
