guys with vista try this open cmd in admin mode and type this in
netsh interface ipv4 set subinterface "NeoConnect" mtu=1430 store=persistent
by default vista is set to max of 1500 so you need to set yours down to the correct lvl
after doing tests on fragment files I came to 1430 now I have no packet losses and the speed as increase by 10 %
for thoes with xp use dr tcp to set your mtu size
