Random continuous disconecting

My problem is really simple: I DC anywhere, dungeons, overworld, raids, BGs, you name it, completely randomly. I had no internet connection issues so at first I thought someone was trying to log in to my game, so I changed passwords almost instantly, but I still kept DCing, so I just thought "Well my gear is soulbound so whatever.". I thought someone wanted my gold, but I was wrong, I did DC, but when I came back, nothing changed, I was still inside a dungeon I was clearing and everything :|
Now I'm just perplex, so I just get disconected randomly, for no reason, any other player knows what this is about?
