I switched from a wired connection to using Vivint Wireless a month ago. The very first day it was on there was an outage. They only give you three days to cancel your two year contact so I asked the installer if this happened often.
They replied it happened occasionally, maybe twice a year. Well I've only been using them for a little over a month now, and it has been offline about 4 times! Often for many hours at a time.
In fact it is offline right now! Luckily my other internet connection was a business line, and they require a two month notification to cancel. I switched back over it using AGAIN so I could write this review.
Bottom line, don't go with Vivint wireless unless you can stand 3-4 outages a month. I work from home so that is not really an option. I am considering paying the termination fee just to get out from under them.
Reason of review: Bad quality.
I liked: Speed when it worked.
I didn't like: Contract, Poor troubleshooting ability.
