try reinstalling the client.but thats seems to be a problem with the modem.try unplugging it for around 10 to 15 minutes.
Do you have downloads going in the background? I noticed that if I have a download going, game lags really bad. I got like 18k ping which was resolved the moment I cancelled the download.
Everyone always complains about lags and DCs, and I never have a problem with it.
Same. My ping is always around 200 ish.
