5 stars: Great app. For this to work properly I had to rename my extended network a different name. I don't recall reading this in the description so hopefully that helps other users. Now it is working seamlessly while I walk around the house.
4 stars: free version worked so I paid for the full version. The problem was that while I was making the purchase the WiFi started to switch and I ended up losing connect while the transaction was happening. so I got charged 2$ but it didn't upgrade me. so I tried clicking it again and it says error you already own this item.
