Connect VU+ Solo to Router with standard Ethernet cable.
If the router doesn't have DHCP you must manually set the IP of your Solo
otherwise the router automatically binds an IP to VU+ Solo.
To Find VU+ Solo IP look at VIX menu/Network.
Use FTP software as mentioned at previous posts.
Enter correct username / password and the IP of your VU+ Solo.
Click Connect and you are ready.
Good Luck.
