It is more the external HUB than it is the card Paco. Both wouldn't hurt though.
FWIW, I used one of the current v204 cards and could only get 70% speed with it.
I went back to what they called the "old world" interface board and I stay over 80% connection speed. Usually 87
I am tempted to upgrade my prs to an alpha, but I just don't want to deal with the connection troubles that seem to come with them.
I don't remember if your on a 4g or an alpha, but if it is 4g, the old card connects better on my pc's.
