I have an issue with the WLAN connection after an automatic firmware upgrade. Failed to downgrade.

[Andy5553]

After an automatic firmware upgrade to 2450B last December, my printer no longer connects via WLAN. The factory reset did not change anything. Since then I've been using a USB connection and that still works fine, but now I want to move the printer to another room and wifi will be vital again.

I have tried downgrading the firmware as I have kept an old version (2313A) in case I might need it for problems like this.

Unfortunately, the printer will not accept a “downgrade” even though I have an older firmware available.

I don't know if downgrading will solve the problem, but I'm really disappointed that HP is preventing me from trying.

Is there any way to get the printer to accept older firmware versions?
