Problem 1: I don't know why but I either got 619 error a lot or the connection lost really quickly (about 5min or so) on my new win7 laptop when trying to connect to a VPN server through PPTP(everything works fine on my old xp laptop though), this bugs me a lot, so I switched to L2TP, it's stable but here comes problem 2.
Problem 2: When I'm on L2TP connection, lots of web pages do NOT load correctly, which means lots of pages take ages to fully load up and the layout is messed up most of the times for some sites like tumblr or amazon or twitter. This is weird, because there's nothing wrong when I'm on PPTP connection to the same VPN server. Why is this happening? I thought there would be no difference since you are connected to a same VPN server.
I've searched around and tried several things like changing MTU etc., but nothing worked. Would any experienced people please help me out?
