Every player in CS2 has faced the packet loss error at some point and within the galore of myths, only a few solutions can mitigate the problem. Packet loss often results in a significant drop in your performances which may cost you an important match so do these things to make sure nothing on your end is causing the problem.
Check your internet
It is preferred that you play over a wired connection despite wireless technology getting better and better. The reliability of a wired connection is significantly more than WIFI and the latter may cause you to get packet loss.
Routing
Sometimes, your ISP routes your network through regions that aren’t optimal for Counter-Strike but there is little you can do to fix it. VPN is one way to go but finding the right one can be a bit of a task. Software like ExitLag may help in some cases but reporting the issue to your ISP will likely be more of a permanent fix.
Background Applications
Forgetting about your background applications is more common than one would assume. If an application is hogging your internet to the point CS has to suffer then it is in your best interest to close them. Close any and all applications that might be using your internet to get the best CS experience.
These are some of the most common fixes for CS2 packet loss if the problem resides on the client end. If Valve’s servers are culprits, then there is nothing you can do but wait until they fix it.
