Broadband: 
* When the whole house is online, do you notice any slowdown or buffering?
* Does your wifi reach every room clearly?     
Television
* Do you mostly watch live channels, or do you prefer streaming and sports?"
* Is one main TV enough, or do you need extra boxes for the bedrooms?
Landline
Are you mostly dialling UK landlines, or mobiles and international numbers?"
Do you actually use the home phone, or is it just for emergencies?"
