Top features of this version:
cFosSpeed now runs with Windows 10
Added support for UPnP capable routers
cFosSpeed can now determine the line speed and the maximum line speed by querying the gateway (router) to the Internet. It supports the functionionality of the UPnP Forum's Internet Gateway Device specification as well as the specification of the DSL Forum. So both types of UPnP routers can help to speed up the line calibration in cFosSpeed. We therefore recommend users turn on UPnP in their routers.
Lots of bugfixes and improved compatibility
