Many thanks for your quick replies.

Unfortunately, a Windows 8.1 computer is the family computer since wife and daughter don't want to learn Linux any time soon..

Somehow, Win8 is blocking the N810, especially strange since even my ancient Windows CE 2.0 devices can access the Win8 shares via Total Commander.

I've set up an FTP server on Win8, but my ISP changes the ip address constantly, and I'm reluctant to use third-party software to generate a static address.
