If you're using Windows 10, then it should be clear that this is a product still in development. The current versions are by no means final and there are many hardware devices that do not yet have Windows 10 compatible driver versions. Windows 10 insider preview is not intended to be used as the primary OS, and is only offered for testing purposes. Until the final release is available, it's recommended that you install and use another version like Windows 7, 8 or 8.1 for your primary daily operating system.
Network adapters, printer drivers and many other peripheral components have no full compatibility yet with this OS so any problems you encounter are highly likely to not yet be resolved by the release of any compatible driver...
