Guide 41: Disable Energy Efficient Ethernet — Preventing LAN Sleep Latency Spikes
Turning off "Green Ethernet" and "Energy Efficient Ethernet (EEE)" in NIC Advanced Settings.
By Shakir Hossain

Many Gigabit NICs come with "Green Ethernet" enabled. When traffic slows down for a fraction of a second, the network card enters a low-power sleep state. Waking back up takes 5–20 milliseconds, creating random latency spikes during matches.
Go to Device Manager > Network Adapters > Properties > Advanced > Set Energy Efficient Ethernet and Green Ethernet to DISABLED.
