Hi pingman support team, wish you the best
there is lag in online games and I did all possible things, changed router configuration, changed mtu, dns with no effect, I tried 2 other router but same problem exists, finally with some search I downloaded pingplotter and it shows me packet loss from hop2 till the final hop so I searched till I knew that it is a problem with my isp, I contacted them and they are really do not understand anything, but they helped me change port in box and port in cabinet with no effect , so I really want to know what can cause the problem? Is it DSLAM? ,bad cable? especially they tell me that my cable is good but really I do not believe them any more, any help will be very appreciated.
