Solved!

Slow Ethernet speed

HP Recommended
Envy 750-435st
Microsoft Windows 10 (64-bit)

(This post relates to my desktop, not notebook, the only option available on this form.)

The full available internet speed availble from modem is not available via ethernet.  When PC is connected via WiFi, speed tests at ~450 mbps, which is about the max available from modem.  But when PC is connected to ethernet, speed is ~95 mbps.     This result is occurs whether the PC is connected directly to  modem or connected through a small ethernet LAN.  The PC's Realtek ethernet controller, PLCe GBE,  status shows 100 mbps.  Autodisable gigabit, energy efficient ethernet, green ethernet aree all disabled.   Controller driver version, 10.19.627.2017, is current.  Windows 10 is also current.

I would like to get the faster speed on eithernet also.  All suggestions appreciated.

Hi, Jim:

 

The only suggestion I can offer is to make sure you are using CAT 6 cables from all sources (modem to router, router to PC),  to the Realtek GBE ethernet controller.

Update:  Slow ethernet speed problem continues despite new driver.   installed a new ethernet adapter driver from www.realtek.com: 10.36.701.2019.   All  configuration properties unchanged (as shown below):  e.g. Speed & Duplex set to 1.0 Gbps Full Duplex, etc.  Results same as with previous driver:  Speedtest ~95 independent of whether the  PC  is connected dectly to modem or connected through router.  The brand new Comcast (Xfinity) modem has both ethernet ports and integral Wi-Fi.  The Wi-Fi speed as measured by cell phone is ~450.    Any further suggestions?

Hi Paul,

You were exactly on target.  Replacing an old Cat5 cable between the modem and PC with a new Cat6 cable solved the problem.  Ethernet speed is now almost as fast as WiFi speed.

Many thanks.

You're very welcome, Jim.

 

There is a difference between connection speed and download speed.

 

To verify that your devices are connecting at the advertised connection speed, go to the Windows control panel>Network and Internet>Network and Sharing Center.

 

Under the first section of the network and sharing center window (View your active networks), click on your ethernet connection.

 

You should see it connected at 1 GB/S.

 

You can do the same for the wireless network adapter (if applicable).

 

The wifi adapter may have a lower connection speed than advertised, based on the signal strength.

 

Download speed is based on a couple of factors...the most important one being what download speed you are paying for.

 

It is not going to exceed that by very much, if anything.

 

My ISP's policy is that if you are getting at least 70% of the download speed you are paying for, then they will not come out to troubleshoot it.
