We had this problem before and he made me a setting that worked... and he says the Art depts Macs don't have an issue. So I copied their settings which use a static IP and I plugged in numbers for my machines IP till I found a free one and it seems better... not great... but so far no page errors...

What does a static IP do that a dynamic one doesn't?
