I've moved your post to the broadband section, where the regulars here might be able to assist in more detail. Although I can't be 100% sure, I can't imagine the lack of a connected TV box is directly causing these issues, except perhaps if you have the connection uncapped and this is possibly allowing noise ingress.
Can you post your modem stats, and also a link to your live BQM? This will certainly help others diagnose the cause of your broadband issues.
To get your modem stats, go to http://192.168.0.1 (or http://192.168.100.1 if you're using modem mode) but don't log-in. Go to "router status" and copy & paste the data from each of the tabs.
If you don't have a BQM running , please set one up. Takes all of 5-10minutes and monitors your broadband 24/7, gathering good diagnosis & evidence of your connection stability. If you do have one, please post a link to the live graph on this thread.

Thanks for using the forums to get this issue with your broadband services looked into, I am sorry if this has been causing some frustration. I would be more than happy to look into this for you.
I am also sorry to hear you're not enamoured with the 360 box 😞 although I understand everyone has their preferences!
I can see you've been given so much helpful information by the VIP's on this thread (thank you guys) has their advice been helpful in getting your connection terminated?
If so, how is your broadband connection now?
I've taken the time to check your services myself and cannot see any major issues that would cause your service to be intermittent.
But please let me know so I can support you further 🙂
