PIXMA TS9520 not working wirelessly

[tuffel57]

I've spent several days on the phone with T-Mobile and online with canon, no closer to a solution to why my ts9520 won't print wirelessly.  During set up, the printer lists my network but when chosen, fails to connect and tells me i entered an incorrect password but it never even asked for a password.  Lost and frustrated.

Hi. I think this may be the solution:

Basically, change your router to use WPA2 and NOT WPA3. 

good luck!
