Pros 1. Has all of the options of s Broadband Router.
2. Battery went for 14 hours with always-on normal-power-level WiFi.
3. Supports 10 users . . or unlimited if you share it on a home network.
4. Touch Screen is nice but has no security feature.
Cons 1. WiFi signal is weak, even with "Boosted" output compared to the WiFi output of a high-end phone used as Hot-Spot.
2. Touch Screen provides full control of dozens of settings with no way to prevent someone else from tinkering with settings.
Summary Overall this is great unit with good stability in an always-on situation.
On average, we get about 2400MB up and down speed in our location, but latency makes the service feel slower than a comparable wired service.
We set this Hot-Spot up as the permanent 24/7 internet service at a mountain home that has no Cable or DSL available.
We found the unit counts the number of Clients it is serving by the number of MAC addresses it sees rather than the number of IP Addresses it gives out to WiFi or other clients . . so by having a Buffalo WiFi bridge linked to the Hot-Spot, the ATTUnite only sees the Buffalo bridge but gives out IP addresses to any number of WiFi clients connected to other WiFi Access points used to distribute the ATT Data service from the ATTUnite. If we let these WiFi clients connect directly to the ATTUnite, the limit of 10 clients would apply, but with the bridge we sometimes have over 20 clients being served by the ATTUnite.
In our case, to get the ATT Signal, the ATTUnite has to sit in a place where house guests have physical access. There is no way to secure the touch-screen from some kid tinkering and breaking our entire network. I covered the entire touch-screen with black Gorilla tape to disable the Touch-Screen since I am 900 miles away from the home most of the time.
We started this arrangement with the previous version of the ATT Sierra Hotspot 14 months ago and it failed at 14 months (no warranty but 8 months left on contract)
