does anyone use WTFast?

[Jinko]

data usually shows up after 5 min or so, but I've never seen any connection problem messages.

I get NA result for Ping Average and 10 Sec Ping and keeps telling me to optimize my settings. I've tried every combination of port, 1 or 2 server choice but still same thing

Have you tried sorting by ping and choosing the lowest ?

If so, it may just be that there is no better connection for you.
