My best friend since middle school got his own place a few years back. His mom's house used to be a rental property but the owner gave the place up to the bank. So they had to move out. His mother had made few if any attempts to actually find a place, so since he was old enough he found a place of his own. His mother and niece also moved in with him, because apparently the bank came a knocking shortly after he got the place and evicted them. He knew it was a terrible idea, one of the reasons he went to find his own place is that he found them all stifling, but he did it anyway.
Now it's a few years later, his mother and niece are living with him, his mother is employed and contributing, but his niece is a deadbeat, she refuses to work, go to school or do anything but be a drain on the household. My friend depends on his internet connection for his job, he's a work at home web programmer.
His niece is changing the settings for his router almost daily, complaining that her wifi is bad. I've gone over there and identified the problem as her room being on the other side of the house from the wireless router in a house made entirely out of concrete. And she insists I don't know what I'm talking about. There have been many occurrences where she changes the wifi settings in such a way that only she can access the network, while my friend is working. She has also called the internet service provider multiple times, and having a tech come out to "fix the problem". Which usually just has them change out the router, requiring my friend and his boss to reconfigure the VPN.
My friend is worried that the ISP will drop them because they are costing them more to have a tech sent out every week than they get from their payment, the ISP is the only reliable ISP in this area. If the ISP drops them he will also be unable to work for all the time it takes for the service to be changed.
He is apparently not taken seriously by anyone in the house, and his concerns are ignored. His mother thinks that him changing the settings back so he can work is what's causing the problems with his niece's internet.
I have suggested he change the password to the router, he apparently did it once, but his mother pressured him to change it back when his niece complained, when he did it again and refused his niece called the ISP and made them change out the router box (again while he was working without telling anyone). I have suggested he kick his deadbeat niece out, but he says his mom won't allow it. I suggested that he tell the isp to no longer take requests from his niece, but he says that while he pays for the internet, it's his sister's name on the account and claims that his sister set his niece up to have more authority than him. I suggested he get the internet changed over, but he requires his mother's car to do it, and his mother again won't allow it. When I offer to drive him he does not want to go against his mother's wishes.
I'm out of ideas what to tell him. His mother doesn't make enough to pay the payments, and he makes twice as much as she does with his programming job. But if things continue with his niece he will no longer be employed, and he refuses to put his foot down. Anybody else have any ideas what he or I should do? I don't want to simply abandon him, we've been friends too long, and I don't want to see him out on the street, but at the same time it seems like he doesn't want to help me help himself, and I'm getting tired of hearing him complain all the time.
