Wireless Issues with Laserjet Pro MFP M126nw

[phalgun27]

Hi,

My printer used to perform fine until I bought Dlink dual band router.  It connects at times to my Mac but mostly it shows printer not connected. Printer connects to my laptop but after I turn off my printer and turn on again, it says printer not connected on my laptop. What would be the reason behind this? I click wifi button on printer and wps button on router; it says connection established but still on my laptop it says printer not connected. I have disabled 5g but the problem still persists. Is there any other way to connect printer wireless without wps? Can you please help me with router settings for the printer? 

Printer shows blacklow message, Is this the reason for not connecting? I am going to change my catridge anyways.

Welcome to HP Forums, 

This is a great place to get support, find answers and tips, 

Thank you for posting your query, I'll be more than glad to help you out 🙂 

As I understand you've got a new router and the printer isn't connecting to it, anymore.

Don't worry as I'll be glad to help, however, to provide an accurate resolution, I need a few more details: 

Are you able to connect all other devices to the new router without any trouble? if no, check the router/ISP, if yes, look below:

Step 1: Restart the computer, printer, and router

Restart the computer, printer, and router to resolve any network or communication error states.

  
NOTE:

The following steps temporarily disconnect network and Internet connections and require restarting your computer. Complete any tasks or downloads in progress before continuing.

1. Disconnect the power cord from the router.

2. Turn off the printer.

3. Close all running programs on your computer, including the HP software installation window, then shut down the computer.

4. Reconnect the power cord to the router, then wait for the Internet activity light to display a normal connected status.

5. Turn on the printer.

6. Turn on the computer.

7. Try installing the HP software again.

   • If the printer is found during the installation, the issue is resolved.

   • If the printer is not found during the installation, continue to the next step.

Step 2: Check the network and printer connection status

Make sure your network is working correctly and that the printer is ready for the network setup.

1. If you are using a wireless router, check your router’s documentation or support site to make sure it meets the following requirements:

   • Check the router band: Many routers can operate in both 2.4 GHz and 5.0 GHz frequency bands, but not all HP printers support both bands. Make sure the 2.4 GHz router band is enabled and broadcasting. If the router broadcasts separate network names (SSIDs) for each band, connect the printer to the 2.4 GHz band SSID.
