cannot exceed 100 mbps

6/22/2020

I subscribe to Spectrum for their ultra fast internet. Their tech came to my house and said that he measured a speed of 400 plus mbps at the modem. He said the refurbished router (that Spectrum also provided) may not be performing
to max and that I should purchase a new router (just to be sure). I did. It did not however change my receiving/sending speeds when using Spectrum's suggested speed test site. I then called Spectrum back and they said my PCI adapter, even though connected
from the router via an ethernet cable to my desktop's PCI card's adapter directly, still was limited to 100/100 mbps. (Also, my laptop tested at the same exact speed of 94 mbps via wi-fi!) They said the slow internet speeds were due to my computers not
being able to receive or send the faster internet speeds. So, I asked my friend who suggested that I ask Microsoft if there is a way to increase the speed, apparently limited by my Realtek PCIe GBE Family Controller (on my Desktop). My tech friend said that
the PCI card mentioned could handle up to 1GB speeds. So, how do I increase the PCI network adapter's speed to accept the 400 mbps speeds. Or is that even verifiable, since my laptops network adapter's speed was limited to 144 mbps and also only received/sent
94 mbps?

My internet speeds seem to be adequate for my computer use. It's just that I cannot verify that I am getting any of the speeds they say they guarantee. I was hoping that an increase in internet speed would help my television's (ethernet cabled) receiving
speeds.

So, in sum: 1) Can I change the limits on either of my computers' network adapters? and,

2) How can I measure and verify that Spectrum is really sending me the faster internet speeds they guarantee?

Network Adapter getting stuck on 10.0 Mbps

When I start my machine my network adapter is limited to 10.0 Mbps. I have to disable then enable it several times to get my 100.0 Mbps back.

All my drivers are up to date, I've just upgraded to Windows 10 but is existed in Window 7 Ultimate as well.

I've switched my LAN cables out with not difference?

What is wrong? Can I replace me network card if there is such a thing?
