Re-Link, Battery or AC : auto disabled gigabit when re-link.

Re-Link, Battery : auto disabled gigabit when re-link and using battery.

This affects shutdown mode (S5) power consumption. What is Shutdown Wake-On-Lan ? Why have this feature ? Who requires to use this feature?Ī.

Disabled : PHY turn off to reduce power consumption but could not wakeup by magic packet.

Enabled : system could wakeup from shutdown by magic packet.

If responses successfully, the jumboframe works.

Ping a large packet to the other machine.

To avoid switch/hub compatiblity issue, please connect the two NICs directly.

If two sides has different jumboframe length limitation, use smaller value.įor example, cardbus 8169 and PCI 8169 should use 3KB.

Both sides enable the jumboframe to a identical value.

If exceeds, driver automatically decreases the length to a proper value. Driver will not enable the option which exceeds the NIC hardware limitation. If users enable both of them, the driver automatically chooses Jumbo Packet.įor switch compatibility and TCP/IP performance, it is better to use Large Send Offload (IPv4) rather than Jumbo frameĪlthough, the Advanced page has Disable, 2KB MTU, 3KB MTU. Users may directly link the 2 machines to avoid the maximum length limitation but this also limit the connectivity.ĭriver will disable Large Send Offload (IPv4) after user enables this feature, TCP/IP could has better performance if it use jumbo frame without large send. If the ethernet switch could not support the jumbo frame, the packet will be discarded. It is out of ethernet specific and has ethernet switch/hub compatibility. It increases the maximum length of one packet. What is Jumbo Frame What is the purpose of this featureĪ. This reduces CPU utilization and improve throughput. The interrupts are automatically trigger in a period. Priority & VLAN Disabled : Both Priority and VLAN are disabled.VLAN Enabled : Only support VLAN and keep priority = 0.Priority Enabled : _Only support priority and keep VLAN ID = 0 _.Priority & VLAN Enabled : Both Priority and VLAN are enabled.Flow Controlįlow control could stop TX side sending to prevent lost packets. OS offloads large TCP/IPv6 segmentation to hardware. This is a newer specification than Large Send Offload (IPv4). OS offloads large TCP/IPv4 segmentation to hardware. This could improve transfer speed and reduce CPU utilization. OS offloads IPv4 UDP checksum calculation to hardware. Options are same as IPv4 Checksum Offload.OS offloads IPv4 TCP checksum calculation to hardware.

#Ipv4 checksum software

Disabled : OS use software routine to calculate checksum.Rx Enabled : OS only offloads RX packets to hardware.Tx Enabled : OS only offloads TX packets to hardware.Rx & Tx Enabled : Both RX and TX are enabled.OS offloads IPv4 checksum calculation to hardware.

If so, the driver stops to load after the wrong MAC address changed. Please do not use broadcast or multicast address.

Here is my current settings: ARP Offload - Enabled (before I destroy my keyboard because I am so tired of lag and disconnects in game) I am trying to get the best possible setting for my Realtek PCI-e GBE family controller network card so that when it will be literally minimal or zero lag when playing online game.
