Thx for answer. Contacting my ISP will accomplish nothing. After TPSA was sold to France Telecom and then rebranded to Orange polish customers are second class and left without real help. One can only get generic answers. We fought Orange service for years but progress is really slow. If nothing helps I will try to reset my whole router setup, reset my pass and try to connect to different node.If that will not help I will be sending official notices to orange to correct the problem. "Normal channels" for customer services just won't work in Poland.
