High ping despite good management?

Hi, I like to play online games, now I have the problem that my ping is very high, even though I have good management. Since I then finally connected with colleagues 3 laptops and playing together we could see that the two had a low ping, I had very high, so we can assume that it has something to do with my laptop. What can I do to keep the ping low?

Wait, how high is your ping?

And WHERE exactly were the laptops of your colleagues? In your local network?

Is this true for individual games or is it always like that?
Just entered the CMD, "Ping Google.de" and once looked at whether the ping is there as high as in the game?
Otherwise, if necessary, select other servers, disable VPNs / proxies.

We were all connected to the same Wi-Fi, and that's not normally in the normal case I'm alone and had always higher ping. The problem is that it fluctuates sometimes I have about 80 but sometimes 140-200

If many devices are connected to Wi-Fi, it can weaken your Internet. So if a download is active now, you get a higher ping (worse performance). Solution better internet

I suspect that you have on your computer malicious software or normal software, which is responsible. This can happen, for example, if you have installed several anti-virus software.
