Wifi rental?

Okay so I rented a room in KL. House owner renovated the house. Created partition in the living room to make more rent-able rooms. Anyway, I have to travel a lot for work so I’ll let the house owner know so she can deduct my water and electricity bills. But somehow I always have to pay full for wifi I barely use cause I got unlimited mobile data. So I asked her and she said wifi is like rental? That it wouldn’t be fair for my housemates to pay extra just cause I’m away?? Please help understand this. I haven’t replied to her cause I’m pissed
