It will work and if installed correctly it should be stable.  It isn't the latest and greatest hardware so it won't have top end throughput but for basic internet service it should pass about 50-60 mb/second.

Do a search on Amazon for Nanobeam AC and you will get results for the Gen2 AC devices which look the same but are significantly faster.  I've never ordered preconfigured devices so I don't know what they are actually configuring.
