Network

🎯 Congestion Provider

High Impact

Controls how your connection recovers from congestion, packet loss, and increased latency.

💡 Reduces latency and improves connection stability

Recommended Provider

CTCP is best for gaming, CUBIC for pure throughput, New-Reno as classic alternative

View current provider

PowerShell / CMD

Get-NetTCPSetting | Select-Object SettingName, CongestionProvider

Change to CTCP (recommended for gaming)

PowerShell / CMD

netsh int tcp set supplemental internet congestionprovider=ctcp

Change to NEWRENO

PowerShell / CMD

netsh int tcp set supplemental internet congestionprovider=newreno

⚡ ECN (Explicit Congestion Notification)

Medium Impact

Allows routers to signal congestion without dropping packets, reducing retransmissions.

💡 Reduces packet retransmissions in congested networks

Enable ECN

PowerShell / CMD

netsh int tcp set global ecncapability=enabled

When to use ECN

Enable ECN only if your router supports it and you have packet loss. Works best with interactive connections and gaming under congestion.

🚀 AutoTuning

Medium Impact

Automatically adjusts the receive buffer size to optimize throughput.

💡 Automatically optimizes connection performance

Configure AutoTuning Experimental

PowerShell / CMD

netsh int tcp set global autotuninglevel=experimental

Possible values

disabled (disabled), normal (default), experimental (maximum performance)

📡 RSC (Receive Segment Coalescing)

High Impact

Combines multiple TCP/IP packets into one to reduce CPU overhead, but may increase latency.

💡 Reduces CPU overhead

Disable RSC (recommended for gaming)

PowerShell / CMD

netsh int tcp set global rsc=disabled

For Gaming

Disable RSC if you prioritize latency over throughput. RSC reduces CPU usage but can add latency.

📤 LSO (Large Send Offload)

Medium Impact

Allows the network adapter to complete data segmentation instead of the operating system.

💡 Reduces CPU load

Disable LSO (recommended for gaming)

PowerShell / CMD

Disable-NetAdapterLso -Name *

View LSO status

PowerShell / CMD

Get-NetAdapterLso -Name *

🔄 RSS (Receive-Side Scaling)

Low Impact

Distributes network processing across multiple CPU cores.

💡 Distributes network load across multiple cores

Disable RSS (only if CPU at 100%)

PowerShell / CMD

netsh int tcp set global rss=disabled

When to disable

Only disable RSS if your CPU reaches 100% during gaming. Otherwise, leave it enabled.

📶 UDP Offloading

Medium Impact

Optimizes UDP packet processing for better performance.

💡 Improves UDP performance

Enable UDP Offloading

PowerShell / CMD

netsh int udp set global uro=enabled

🌍 Teredo and 6to4

Low Impact

Required for Xbox LIVE and some games on Windows 10/11.

💡 Enables support for online gaming and Xbox LIVE

Enable Teredo

PowerShell / CMD

netsh int teredo set state natawareclient

Enable 6to4

PowerShell / CMD

netsh int 6to4 set state state=enabled

🔍 Verify Configuration

Low Impact

Check current TCP/IP and network adapter configuration.

💡 Verifies that changes were applied correctly
