>> I tried setting the MTU and MRU to 1500 with the >> same results (and a slight drop in transfer speed). With PPPoE, from what I've read, the "ideal" MTU setting is actually 1492. For what it's worth, I did try the Roaring Penguin with no problems. I have a Linksys router that handles PPPoE for me, so I don't use it anymore. Can you disable your firewall software even temporarily ?? May be a problem with it. Good luck Hall
