While at a hotel I noticed that in order to connect my Echo Dot to the hotel wifi, the app on my phone had to have the Echo connect to the hotel hotspot while I was connected directly to the Echo. This was in order to login using the hotels web login. This had an interesting side effect. The Dot was effectively acting as a wifi extender to my phone which has very poor wifi strength. I was able to fully use the internet on my phone while connected to the Echo's wifi setup. The Eco obviously has the capability to extend wifi so I find it odd that it's not a feature. Here's hoping that an app can be developed to enable this since it's already present in the hardware. Any thoughts?
