All is working fine and getting 70/20 mb speeds, this is when I connect the cable to port 1, 2 or 3. However when I connect the cable to port 4 GigE it just drops connection. I open a dos command and ping a random website and get several timeouts every 2-3 successfull pings. Browser tries to find a website but eventually times out after 30 sec with an error connection problem. Plug it back into any other port and its blazing fast again. Is my home hub 3 GigE port broken and need a new one or is it something else? I have a NAS and really could use the gigabit speeds.
