Gaming Lag Fixed: 800ms Spikes on a 500Mbps Sydney Line

Paying for gigabit-class fibre and still teleporting around the map? We see this weekly. One Sydney household on a 500Mbps plan was hitting 800ms in Valorant every evening.
Layer-by-layer isolation
- Software: a game 'accelerator' (VPN) was routing OCE-server traffic overseas and back — turning it off alone cut ping dramatically.
- LAN: the gaming PC sat on a wireless mesh node; competitive play needs wired backhaul or a direct cable.
- Router: QoS reconfigured so the PC gets priority over the household's streaming.
- The hidden one: on Telstra/Optus modems with a backup 4G SIM, a mis-configured WAN silently falls back to mobile data — one Brisbane client's '500Mbps' was testing at 24Mbps for exactly this reason.
Result
Evening ping down from 800ms spikes to a stable sub-30ms on OCE servers.
