I recently upgraded to 400mbps internet speed but my internet speed test showed <100mbps.  I reported the issue to my provider, Spectrum, and tech came out and replaced some cable connections as well as my modem and Wifi router.
No change; still 100mbps. When I checked speed by pinging from the DOS prompt, my ping speed is 32ms, which I understand is pretty fast. I discovered I was using a cat5 wire and replaced with cat 6.
No change; still 100mbps.
After researching on the internet, I changed settings on my Realtek PCIe GbE Family Controller Network Adaptor to 1GB Speed & Duplex.

No change; still 100mbps.
I updated to the latest network adaptor driver from the Realtek website;  version 10.50.511.2021. This update was not approved by Microsoft, and was not in their catalog of accepted drivers.
No change; still 100mbps.
I tried the speed test from different browsers, Chrome, and Edge, and used task manager end task to stop redundant tabs running related to extensions.
No change; still 100 mbps.
I have verified that my computer is capable of higher internet speed, (it runs an Intel CPU at 2.4 GHz), and I am sure it is available. I suspect I have a setting wrong somewhere, but I have run out of ideas. Any suggestions?

Hi:

 

Your PC's ethernet adapter is definitely a gigabit model, so I don't know why it is capped at 100 MB/S.

 

What does the actual connection speed indicate?

 

You can check that by going to the Windows control panel>Network & Internet>Network & Sharing Center>click on your network connection on the right side of the 'View your active networks' section on that window.

 

It will indicate the actual connection speed.

Thanks for your response. I'm not surprised to see it's sitting at 100mbps.

In addition, I have a battery backup power strip that I passed the internet connection cables through, (we have a lot of lightning and power burps here). I changed the connection and bypassed the backup, running the connection cable straight to my machine. Still no change.

You're very welcome.

 

Assuming you have a cat 6 ethernet cable going from the cable modem to the router as well, unfortunately I have no idea why the ethernet adapter is stuck at 100 MBPS.

 

It definitely should be connecting a 1 GB/S.

 

I just checked my HP notebook, which has a Realtek gigabit ethernet adapter and I tested that it connects at 1.0 GB/S.

 

The Speed & Duplex advanced setting for the Realtek ethernet adapter in my notebook is set to Auto Negotiation, not 1.0 GB/S full duplex like yours is.

 

You may want to try that setting if you have not done so already.

 

The Speed & Duplex setting for the Intel gigabit ethernet adapter on my Dell Optiplex 7050 tower is also set to Auto Negotiation.

As you suggested, I changed the speed & duplex setting to auto negotiation; see next.

LookMaNoHands_0-1636303644409.png

Changed back to 1.0 GB. See next.

Downright weird.  Just checked the tech installed cable from modem to router; marked cat5e. Googling says the 5e can handle up tp 1000mbps. Switched it out anyway with my new cat 6. No real difference, except for ping.

Definitely downright weird, and I am completely stumped as to why that is.

Well, buddy, with all the thousands of messages and thumbs up you have in your history, if you don't know, I guess I'll be treading water for quite a while. 
It's Sunday, so maybe a prayer for divine guidance would be a good idea.
Thanks for your input.
 Best Regards.

You're very welcome.

 

I'm sorry that I wasn't able to help you get the ethernet adapter to run at 1 GB/S.

 

There is something you can do to achieve close to gigabit ethernet speeds, which would require having a free USB 3 port, and that would be to purchase a USB to RJ-45 gigabit ethernet adapter.

 

Something like this...

 

Amazon.com: Amazon Basics USB 3.0 to 10/100/1000 Gigabit Ethernet Internet Adapter : Electronics

HP Recommended

I think I'll try that. I don't have a free port, but I have a multiport plugged into a single port(like an extension cord multiplies the available plug-in ports) that should work. I have little to lose, and much to gain.
Thanks.

HP Recommended

You're very welcome.

 

As long as it is all USB 3.0, it should work.

 

The adapter will work in a USB 2 port but won't reach the gigabit ethernet speeds.
