Fix Packet Loss and Network Jitter in CS2
Perform an Internet speed test
waveform.com/tools/bufferbloat
If you do poorly on this test, it's a problem with your Wi-Fi. Try restarting your router to check if it can solve the problem

Try these Network Reset Commands one by one

ipconfig /release
ipconfig /flushdns
ipconfig /renew

Then

netsh int ip reset
netsh winsock reset

If all else fails, try switching to a different Wi-Fi provider or use a wired Ethernet connection, as most CS2 network jitter and packet loss issues are caused by your internet service provider.
