Thank you for the feedback.
I will try to connect the UPC TV box using the pw without the WPS button.
I changed the password for the main Wifi as it is the safe thing to do.
Also may I point out that the CONNECT BOX IP Address is NOT a SECURE IP.
UPC should consider changing all Connect Box ip address to a more secure IP, as this can lease to Hackers being able to access household Connect boxes very easily. Once they have access to your home connect box they can easily access other data. I study Cyber Security and I know this would be an easy access point. You need to change the IP addresses so that it uses HTTPS and not just HTTP.
I cannot connect directly to the Connect Box as it is upstairs and directly connects to my DeskTop PC which has no WiFi and my main TV is downstairs etc
I have to use WiFi expanders to boost the signal downstairs, but I could try connecting an Ethernet cable to the WiFI booster and the UPC TV box.
