Hey, so I'm having some ping problems. I've been playing MSC since 3 years ago or something. Anyway, about 2-3 times (excluding right now) I've had a sudden unusual ping problem where when I view a server on the Server Browser, it has low ping for me (around 140 because I live in Iran). But when I join that server, my ping suddenly starts going way up. Between 400-1100. Keeps going up and down for no reason. I have no background downloads and I've tried port forwarding but it doesn't work. As I said, I've had this problem before. I couldn't fix it back then either. I just came back a while later (probably months) and it was magically fixed. Right now I'm having this problem and it's really annoying. Does anyone have any idea on what I should do? IMPORTANT: I also sometimes get kicked form the server with the message "Reliable Channel Overflowed". I think this is the key word for my problem. Extra info: as I said, the ping generally being high, it does go up and down every few seconds . From a minimum of 380 to a maximum 1400. So if I run straight, at one point it will be a fluid move and at one point I will suddenly get stuck or be pushed forward. I don't think it's because of my computer because I haven't change my computer or it's parts since then. And my internet service has actually been better than ever. My game is up to date. (NOV2016a update). I have tried reinstalled Half-Life and MSC but it didn't work.
