Extreme high ping while playing Gmod

Hey,

Since a few hours my ping is like 500 - 1000
I did run a speedtest at speedtest.net and this are the results

And, that’s the weird thing, I’ve such a good speed, but an amazing high ping at GMod.
I hope anyone can help, cause it lags me.
Btw, I have this on all the servers, doesn’t matter where they are hosted. Other people on the servers I tried don’t have the same problem.

Lock it please. It’s already fixed :open_mouth:
I think it was just a router fail…
