I am now in South Korea, which is reported to have the fastest internet. (It is kind of true, as it is quite easy for me to get a first post or get in a packed Hangout1 on Google+. If this seems to be an ad for Google+, feel free to edit it out.)
The thing is, with this seemingly fast internet connection, I cannot have a fluent video chat with my friends in China, Japan, United Kingdom and United States.
Now I deal with it by dialing a VPN, and after this, the video chats (including 10 people's Hangout) become fluent.
I want to know where the problem lies, and how to deal with it. I do not like to dial VPN so often anyway.
1: Hangout is a group video chat for at most 10 people.
