Upgraded Network services and no deskjet 2542 has never connected to wireless

[TMSisannoyed]

Our HP wireless printer was connected to my IPhone, Acer laptop under Microsoft operating system as well as my MacBook operating system. It worked perfect. We upgraded our wireless internet system and the printer has never connected to any device properly since then.

Hi @TMSisannoyed,

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.

I understand that you are unable to connect your HP Deskjet 2542 All-in-One Printer to the wireless network after upgrading your wireless internet system.

This issue could occur if the wireless setup after the upgrade is not proper.

Let's go through a few steps to troubleshoot this issue.

And here's the step by step guide for you in the link depending upon the operating system installed on the computer:

1. Wireless Printer Setup (Windows)

2. Wireless Printer Setup (Mac)

Let me know how this works.
 

You have a good day ahead.
