Conection lost - please helpp

Hello, it has weeks that i have the same problem, the normal game and after a moment is disconnected, i enter again and i fall again, i play another time and the same.

I verified that my internet is not, i have optical fiber and it works everything without any problem, i do not believe it is an addon, i only have 2, the recount and the gs and i have them before i begin to pass this.

It is very disturbed, always disconnected in the middle of a dungeon or bg, i can't raid for fear that it falls in the middle.

I hope someone can help me, thank you.
