I have a laptop connected in a network via HomePlug to my desktop which has the ASDL modem connection.
The problem is that a number of (most) websites will not load from the laptop (client). It is also not possible to ping these websites and get a reply. This site is obviously one of the exceptions. There is no problem in connecting from the desktop (host).
I have tried MTU value changes, but with no effect. I have also tried running the Homeplugs directly from a mains socket, without a surge protector - no better.
Would be grateful for any ideas.
