I have a ts9020 canon printer. i got a new wifi router + network. tried to connect my printer to the new wifi, won't work. 

when i do a manual connection, it doesnt let me enter a password at all. it just automatcially starts connecting and fails. when i connect to a different wifi, it lets me enter a password. its only my wifi that wont let me enter a password.

i tried resetting all settings and it still doesnt work. i tried setting it up with the app from my phone (android) and it still doesnt work. it gave me an error code, 3441, and said it wouldn't connect. i followed the youtube official tutorial too. its been like this for MONTHS and im so tired of it... PLEASE help me i dont wanna get a new printer
