Read page 34 onwards of the PDF document that covers the wifi setup via USB using the software's installed when the printer drives were installed.

Hello,
I have a Phaser 3020 printer. I had no problem with this printer untill i decided to change the wi-fi password. I can”t use it wireless anymore. It prints only with an USB cable connection.
Is there something i can do to print from any device again?
Thank you,
Ina
