Well, I guess the person who first posted has finished up school, but may still want to know as did one other poster about the Enterprise. There are issues with this on several levels, but I'm going to talk to the network level and then if are any other questions, I can go from there.
It's not that I am for or against Amazon, but from a technological standpoint, Amazon will never support those legacy 802.11 wireless protocols. Take for instance a/b/g/n, which is now legacy. Your wireless router and your smart phone have 802.11n and you think you should be humming along at speeds between 150mbs+ (802.11n theoretical max throughput is 300mbs). All you need is an 802.11g device or worse, an 802.11b device to ruin your day. Here's why. By the IEEE standard for 802.11n wireless routers, any devices with 802.11b or g will cause all devices to have their bandwidth down regulated by the router to either b (theoretical max 11Mbs) or g (theoretical max 54Mbs) bandwidth speeds and everyone now crawls along. Your sitting there with your echo that supports 802.11n and you are wondering why your music won't play.
My organization provides data to the public the moment it is calculated. Our network speeds are driven by some factor related to the ever increasing speeds of the residential sector. We are starting talks about converting one day to terabit networks. Amazon has that same pressure. Media is data and it's a lot of data. Business does not typically have that volume of data and I'm talking they don't have it by orders of magnitude less. I know because we have business offices too and the bandwidth they need is the bandwidth our data networks used in the mid 1990's.
As much as you want to believe business is everything, trust me when I say, Amazon has a data plan that will only continue to keep them moving forward for faster and faster bandwidth speed when it comes to them supporting their customer base, their home users... They aren't ever going to look over their shoulder. Aren't you always looking for the next fastest cell phone and/or wireless home routing device?
Most residential people do want the next fastest whatever it is. They are the people that are in the Amazon consumer market (games, videos, voice and other data products). For Amazon, that IS their business.
Your only hope is in the 3rd party arena. You need a VPN client on your Echo. It may exist; it may come in two years; or it may never materialize. Everyone is going to have their own requirements for endpoints, too, which will complicate the 3rd party solution. Hopefully, something will eventually bubble up to the top and solve your problem. Goodluck!
(P.S. For those of you wondering what to do with your 802.11n wireless router/switch/hub or some combination therein, upgrade it to 802.11ac. It's theoretical speed is around 1.3Gbs and it supports legacy wireless. 802.11ac has nothing to do with 802.11a. It is its own wireless protocol altogether).
