My Airave came up in 20 minutes and lit up the entire house (5250 sq. feet) like a Chrismas tree!!! I live in a Sprint "dead zone" and now I have 5 bars on the 1st floor and no worse than 3 bars on the 2nd floor and basement. The Airave really does the trick! Paying a monthly fee of $4.99 just to have the improvement of service is well worth it and I'm paying another $10 for unlimited service for my wife who is home most of the day and now uses her Sprint phone for the vast majority of her calls. Now that we have the Airave, we may elliminate a 2 lines that are costing us almost $100 a month! So paying $15 a month for the Airvae is a no brainer!!! I lvoe this thing!
