Power consumption is going to be miniscule, especially if the consumer 
opts to use the cable company's built-in wi-fi themselves. If someone is 
really that concerned about their electric bill they can unplug it when 
not in use. Not practical if there's an ATA in it used for landline or 
you have devices requiring Internet access 24/7 like security systems or 
IoT. Of more practical concern is RF interference.

Typically the cable company puts their box in a convenient location for 
access, either near where the cable comes in to the house or maybe 
behind the TV. This often isn't the best place for radio coverage but 
can create strong interference near the box.

If the customer doesn't use the cable box's wi-fi and installs their own 
access point(s), there is no convenient way for them to turn off this 
functionality. Many customers don't even know it exists. Most front-line 
cable support techs don't either.
