Use Ethernet where possible
A wired Ethernet connection usually gives lower and more stable latency than Wi‑Fi. This is one of the best upgrades for gaming.
Reduce network load
Pause downloads, cloud backups and streaming on other devices before gaming. Upload traffic can cause lag if your upstream bandwidth is limited.
Avoid unnecessary VPNs
VPNs can add routing distance and increase ping. Try testing with and without the VPN to compare.
