Got stuck at "Receiving Character List"

Heyo, last night I were in Netherstorm then got frozen , logged out. I tried to log back in and it got stuck at "receiving character list".
I then turned off computer, reset router, tried again , it stuck the same.
Today i try to log back in again and the similar problem.
I searched on web and tried many method like changing MTU to 900 for Asia countries etc, still nothing good comes out.

Anyone have similar problem or know how to fix it please help
