I’ve seen a lot of people do various things to network to the Polar. It’s not as hard as you might think. To be able to connect to the Internet and to your Polar at the same time, you can setup a virtual ethernet interface. Then, assign an address to that virtual interface on the same network as the polar (192.168.1.x other than 192.168.1.100), and voila… full connectivity.
