Check your Internet Connection maybe that's the problem if you are not using any software like WTFAST/PINGZAPPER or any other software, for now all is good your the only one who experience the DC thing.
Since I started using WTFast I get dced very frequently. I've stopped using it and I rarely get dced. So I'm gonna assume the problem lies with WTFast. Try playing without it.
The problem is in WTFAST try to use the stable version of wtfast so you won't get DC or for better gamming try without wtfast since you are from EU your potting will be the same.
