Centennial Wireless Complaint - Don't buy the Sierra Wireless Air Card (especially if you're on Mac or have a metal roof?)
I have a Sierra Wireless Air Card from Centennial and it is the slowest service I have had since dial-up first came on the scene many years ago. Remember when you could cook dinner for the family and come back and still be waiting for it to do something?
That is how this service is for me. In the store (one of the many times) they noticed I had a Mac laptop and said that it didn't work very well on a Mac. Which was never brought up when they were sell it to me. They also asked if I lived in a house with a metal roof. I do not. But, excuse after excuse...the problem never was resolved. The staff had attitudes also.
Sorry, I did business with Centennial. No one helped me. I am very disappointed.
