WAP2 code needed for iMac as new FF recently connected

[wendee]

Fibre 150 connected on 9/6/25 with new white box. When changing the passwords everything worked except my old iMac stating it requires a WAP2 code. My cannon printer won't print using air print which is connected to the iMac either. 
Also the smart tv won't connect. 
all other phones laptops and door cameras have connected although the back door is showing as poor connection which didn't show with my older slower broadband connection.

@wendee if you have a white Sky hub go into the advanced settings for the hub in the My Sky app and chsnge the WiFi Security level from WPA3-T to WPA2. The WPA2 code is the password printed on the label of all Sky hubs assuming you have not changed it yourself. Some older devices wont connect to the WPA3-T security level the newer hubs use despite it being designed to support both WPA2 and WPA3 devices.
