Is it my computer or the game?

I always get DC sometime back to back to back, what doing on here?

 

You got DC after 5-10 mins online, or when u chose a char?

 

Usually disconnections have nothing to do with the server unless one of the following happens.

1- You're trying to join a party or alliance when they're bugged. This will cause that you disconnect every single time you try to join one.
2- The server is lagging, this mostly happens to everyone altogether and it mostly requires a server restart.

If none of the above apply to your case then it's probably a problem with either your computer or your internet connection.
