Hi DG,
thanks for your reply.
My new router (from Time Warner Cable) is a Motorola SBG6580.
Besides the fact that I set all the machines in my network to static IPs, the router comes with a IP reservation function, so you can activate the automatic IP assignment on all your computer, but tell the router to always assign the same IP address to a certain MAC address.
The same feature was present in my previous router, but in that case, both in static and in dinamic IP assignment, the connections between the Host and the Slave was light-speed fast.
I will contact VSL at the email address you suggested.
Thank you so much.
Luigi.
