Realtek PCIe GBE Family Controller keeps disconnecting - my fix. So I had this issue where my ethernet connection on my Lenovo B570 laptop keeps disconnecting about every couple of minutes and the link lights would turn off then it would reconnect.
- Realtek NIC running at 100Mb/s rather than 1000Mb/s 4 answers
I have an asus Gigabit Router and a gigabit NIC (Realtek PCIe GBE Family Controller) witch is running at 100Mbps rather than 1000Mbps (1.0 Gbps).When I use an old laptop on the same Ethernet cable(cat6) its running succesfully at 1.0 Gbps.Means there's no problem with the setup, router nor the cable.I tried changing the speed & duplex from auto negotiation to 1.0 Gbps but its still running at 100.0 Mbps.I also have the latest driver update for my NIC.
I think im missing something but what ?What could be the problem ?

There are several different Realtek chips which identify themselves as Realtek PCIe Family Controller. Although many of these chips support 1 Gigabit ethernet speeds, some do not, and there are new laptops sold, even now in 2017, with only a 100MB/s Realtek chip. Unfortunately, the HP Envy machine I got at Costco is one of them.
To check if your hardware supports 1 GB/s, go to the
properties
page for the ethernet
adapter and configure
the driver. On the advanced
tab, select speed & duplex
(you might have to scroll down in the list). Check the dropdown on the right to see if 1000 Mbps is listed.If the chipset in the laptop does not support Gigabit ethernet, but has a USB 3.0 port, then a workaround is to use a (e.g.) USB 3.0 to 10/100/1000 Gigabit Ethernet Adapter.

Can you verify the CAT6 cable used (are you sure it's not CAT5/CAT5E?) is wired the same each end (check the colours on the underside of the RJ45's). Basically a CAT6 cable is a CAT5 cable with additional shielding.
If you had one end wired as T568A and the other as T568B then what you have is actually a 'cross-over' cable and not a 'patch cable'/'drop lead'. Originally intended for connecting 2 PC's together without a hub/switch the mistake is easy to make when wiring patch cables/wall sockets.

Additional details here: http://dox.ipxe.org/realtek_8h_source.html
Speed & Duplex
Switch link speed and duplex.
- Auto Negotiation : switch choose best speed automatically
- 10 Mbps Half Duplex : highest link speed is 10 half
- 10 Mbps Full Duplex : highest link speed is 10 full
- 100 Mbps Half Duplex : highest link speed is 100 half
- 100 Mbps Full Duplex : highest link speed is 100 full
- 1.0 Gbps Full Duplex : highest link speed is 1000 full
NetworkAddress
Change the MAC address of network card.Please do not use broadcast or multicast address. If so, the driver stops to load after the wrong MAC address changed.
IPv4 Checksum Offload
![From From](/uploads/1/3/3/2/133281081/557121782.png)
OS offloads IPv4 checksum calculation to hardware.
- Rx & Tx Enabled : Both RX and TX are enabled
- Tx Enabled : OS only offloads TX packets to hardware
- Rx Enabled : OS only offloads RX packets to hardware
- Disabled : OS use software routine to calculate checksum
TCP Checksum Offload (IPv4)
OS offloads IPv4 TCP checksum calculation to hardware.
- Options are same as IPv4 Checksum Offload
UDP Checksum Offload (IPv4)
OS offloads IPv4 UDP checksum calculation to hardware.
- Options are same as IPv4 Checksum Offload
Large Send Offload (IPv4)
OS offloads large TCP/IPv4 segmentation to hardware. This could improve transfer speed and reduce CPU utilization.
Large Send Offload v2 (IPv4)
OS offloads large TCP/IPv4 segmentation to hardware. This is a newer specification than Large Send Offload (IPv4).
Large Send Offload v2 (IPv6)
OS offloads large TCP/IPv6 segmentation to hardware.
Flow Control
Flow control could stop TX side sending to prevent lost packets. Empire season 2 trailer download.
Priority & VLAN
- Priority & VLAN Enabled : Both Priority and VLAN are enabled
- Priority Enabled : _Only support priority and keep VLAN ID = 0 _
- VLAN Enabled : Only support VLAN and keep priority = 0
- Priority & VLAN Disabled : Both Priority and VLAN are disabled
InterruptModeration
The interrupts are automatically trigger in a period. This reduces CPU utilization and improve throughput.
Receive Buffers
- Receive buffer MAX (512)
Transmit Buffers
- Transmit buffer MAX (128)
Jumbo Frame
- 2KB MTU : MTU is 2*1024 bytes
- 3KB MTU : MTU is 3*1024 bytes
- 4KB MTU : MTU is 4*1024 bytes
- 5KB MTU : MTU is 5*1024 bytes
- 6KB MTU : MTU is 6*1024 bytes
- 7KB MTU : MTU is 7*1024 bytes
Q. What is Jumbo Frame What is the purpose of this feature
A. This feature is for performance. It increases the maximum length of one packet.
It is out of ethernet specific and has ethernet switch/hub compatibility. If the ethernet switch could not support the jumbo frame, the packet will be discarded. Users may directly link the 2 machines to avoid the maximum length limitation but this also limit the connectivity.
Driver 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 users enable both of them, the driver automatically chooses Jumbo Packet.
For switch compatibility and TCP/IP performance, it is better to use Large Send Offload (IPv4) rather than Jumbo frame
PS:
Although, the Advanced page has Disable, 2KB MTU, 3KB MTU, .. 7KB MTU. Driver will not enable the option which exceeds the NIC hardware limitation. If exceeds, driver automatically decreases the length to a proper value.
How to verify jumboframe works :
- Both sides enable the jumboframe to a identical value. If two sides has different jumboframe length limitation, use smaller value. For example, cardbus 8169 and PCI 8169 should use 3KB.
- Both side must disable firewall.
- To avoid switch/hub compatiblity issue , please connect the two NICs directly.
- Ping a large packet to the other machine. Ping xxx.xxx.xxx.xxx -l 65000
- If responses successfully, the jumboframe works.
Shutdown Wake-On-Lan
- Enabled : system could wakeup from shutdown by magic packet
- Disabled : PHY turn off to reduce power consumption but could not wakeup by magic packet
Q. What is Shutdown Wake-On-Lan ? Why have this feature ? Who requires to use this feature?
A. This feature is for power consumption. This affects shutdown mode (S5) power consumption.
Auto Disable Gigabit (PowerSaving)
- Disabled : Always enable gigabit
- Re-Link, Battery : auto disabled gigabit when re-link and using battery
- Re-Link, Battery or AC : auto disabled gigabit when re-link
Q. What is Auto Disable Gigabit ? Why have this feature ? Who requires to use this feature?
A. This feature is for power consumption.
When users change the setting to Re-Link and user unplugs and plugs network cable again, the driver will automatically disable gigabit capability. Gigabit has much higher power consumption than 10/100 MBps. For notebook users, it is recommended to turn on this to reduce power consumption.
PS :
This option MUST change to Re-Link to enable Auto Disable Phy'

When users change the setting to Enabled and the network cable is unplugged, the driver will automatically disable PHY. To use this feature, user MUST enable Auto Disable Gigabit first. Because gigabit link establishment takes longer time, driver needs user disable gigabit to reduce the linking time.
PS.
You can download the apk file from the methods that are mentioned above or look for the apk file over the internet. Download game dustoff heli rescue 2. •, an android emulator essential to run android apps on your computer.
If both of them enabled, the linking time will be increased but power consumption reduced. The linking time about 5 seconds.
Receive Side Scaling
- Disabled : RSS disabled
- Enabled : RSS enabled
- This feature is for better CPU utilization balance while internet browsing and file copying.
- This is especially good for complex homepage content with a lot of pictures.
Because OS will create one TCP connection for each picture. Those TCP connections will dispatch to different CPUs. From driver layer to application layer, data transfer and picture decoding runs on different CPU.
