I ordered the seld install unit and left by my widow upstares. I was getting about 75 MBps and did everything i was not able to since i am an elderly and also dont fee like getting up on a ladder i requested them to have someone come and install it in my roof. I had to wait about 2 weeks but my internet was working so it was not urgent. They guy came and installed it on top of a 2 story building. The speeds and latency have improved tremendously since then. I am just happy that i finally can stream without buffering.
