Why I Don't Have Internet

I was on my way home from the city yesterday, and I was looking at house with the SmartBro antenna. All of the houses have one thing in common, all of them have their antennas pointed to one direction. While ours has shifted to a different direction. Must be from the winds a couple weeks ago. I've mentioned this to my sister to have someone go up on the roof and try to shift the antenna but she hasn't even done anything about it. I do get times when I get a connection, but only briefly and this has been going on for almost 4 weeks now.
