Know what the numbers mean
Ping is a round trip delay to a particular endpoint. It is not a universal score: distance, route and server location matter. Jitter describes variation in delay. Packet loss means some packets fail to arrive, which can cause corrections, rubber banding or missing actions. A single speed test result cannot fully describe a game connection.
Use a controlled comparison
When practical, test the same game server at a similar time on Ethernet and Wi Fi. Keep downloads, cloud sync and streaming under control. Note whether the game reports packet loss and compare it with a separate ping test to a relevant endpoint. A test to a nearby router can reveal local Wi Fi issues but does not measure the entire route to the game server.
Improve the local link
For Wi Fi, test closer to the access point, reduce obstructions and compare bands or channels using your router's supported settings. Ethernet removes one wireless segment and is a useful diagnostic baseline. It does not fix congestion or routing problems beyond the home.
Check for upload saturation
Large uploads and backups can fill the upstream queue and increase delay for everyone. Pause one known transfer and repeat the same test. If latency drops only when the transfer stops, look at router queue management or schedule heavy uploads outside play. Do not change random router security settings to chase a ping number.
Interpret the evidence
Compare results over several minutes and note time, server and connection type. If only one game or server is affected, the issue may lie outside the PC or home network. Share the evidence with the ISP or game support rather than claiming that a local optimizer can control the entire route.

Guidance is general. Check the documentation for your exact hardware, Windows version and game before changing system settings.
