I get a lot of signal interference where I live and, from time to time, look at gadgets that might sort that out. Considering that laptops don't come with a directional aerial, it seemed worth trying and Wise Tiger also freely showed the tech that's inside it was a good selling point. Although it didn't quite sort things out but did improve it a bit, the software does monitor signal strength, something I've missed in successive versions of Windows and in combination with a Range Extender has proved to be a good combination so far. It's a step in the right direction and if you only have moderate signal interference resulting in your laptop crashing, this dongle is at a cheap enough price to worth giving it a go.
