Connection freeze!

[Oneelement]

Hello, ive been playing this game for the last week and have had 1 very annoying problem. When i play the connection freezes and it doesn't let me cast spells, interact or do anything. Just walk, happens in bg's, raids, dungeons... everywhere. my internet is good, ive tested it by playing other games. its not my pc freezing because as i mentioned earlier i can still move and work the UI. restarting the game solves it but not always, sometimes it doesnt let me back on for 30minutes or so. But its not a solution restarting the game all the time anyway, happens about 3-6 times a day. is it problems with the server or something else? help please. Thanks

It is not because of your internet, server is in mainteance.
