download and you'd expect something to happen. absolutely nothing at all. was recommended by someone at Chromebook support. i'm not surprised nothing happened. like most wifi connectivity problems with a Chromebook the standard response is to blame something else. the person who recommended this was very adamant that the issues lie with the router. hopefully one day what appears to be a pretty large problem w Chromebooks...disconnect from internet, any wifi, any router, any connection while it's only the chromebook that disconnects. yeah right, chromebook is the only thing to disconnect from many networks, many routers, many hotspots but it's the other network, other router or other hotspot and this nothing of an app was to help with a problem that is really chromebook enthusiasts don't want to admit that the problem lies w the chromebook.
