Slow Ethernet Speed

[SpiderBaby]

Serial Number:  [Personal Information Removed]

Product N5Y98UA#BL

Laptop is also known as to as HP 80C5(CHV)

I recently upgraded my internet to get 100 MB/ps.  I have three computers in total that I have connected via a cat 5e cable. Each computer has its own cable. On the other 2, I am able to get 100 MB/ps connection speed with no problem.

On my HP laptop, I am not and it does not matter what changes or tweaks I do, based on information I have found on the INTERNET.  It is as though  is some internal setting that is throttling the speed.

When I connect via the WIFI, I get the following results when I do a speed test:

PING:  11

Download Speed:  32.2 MB/ps

Upload Speed:  10.6 MB/ps

When I connect via my ETHERNET CABLE, I get the following results when I do a speed test:

PING:  9

Download Speed:  45.4 MB/ps

Upload Speed:  10.8 MB/ps

I even went right beside the router/modem, and used a cat 6 cable, that was three feet long, and the speed was still the same.  So, it has nothing to do with the cat 5e cable.  It also made no difference when I switched to a wireless connection.

Not sure what to do next.  Up till now the laptop has had no problems or issues.

The card itself is based on a Realtek PCIe FE Family Controller, Driver Version 10.1.505.2015

Can you outline what if any are anything I need to change in a step by step fashion?

Or, if there are no steps - do I simply need to upgrade the network card?

Or is there anything else that I could do/should do to rectify the problem?

The specs of your machine is

      https://support.hp.com/au-en/document/c04791282

It ONLY has  Integrated 10/100 BASE-T Ethernet LAN network card (adapter). Replacing it is a bit hard because it is embedded to the System board.

I'm using the following adapter (there are many different brands around):

and I've got 2 more USB 3.0 ports
