Hi! Thank you for choosing Just Answer! My name is ***** ***** I will be assisting you today. Give me just a moment to look over your question.
I see that you are essentially just wanting to connect your printer wirelessly again but you have changed your security key. Is this correct?
I have two wonderful visuals that will show you exactly what you need to do:
CLICK HERE TO SETUP YOUR WIRELESS CONNECTION FROM THE PRINTER
If you want to setup via your PC or MAC:
CLICK HERE TO SETUP YOUR WIRELESS CONNECTION VIA TEMPORARY USB CABLE
You will find your NEW network name and use your NEW network key to authenticate the printer.
Then try to do a test print once you are finished.
Please let me know if this doesn't work, as we may have to do more troubleshooting.
If this resolves your issue, please kindly rate my answer with 5-stars so that I may receive credit for assisting you today! Thank you!
