Limited to 100 mbps instead of 1000 mbps (1 gbps).

Hello,
I have encountered this problem several times.
Every other day, my connection on my Computer is limited to 100 Mbps instead of 1000 Mbps (1 Gbps).
In fact, only my PC is having this issue; another desktop (connected via Ethernet like I am) does not have this problem, nor does a laptop connected via Wi-Fi.
I have tried changing the Ethernet cable, downloading the latest network card drivers, and turning my PC and Box off and on again, but nothing works!
I have Fiber from Free, and my Computer is two and a half years old.
Here are two photos taken three minutes apart (after restarting my computer, sometimes I have 1 Gbps when I turn it on, only to lose it later):
Please, help me!
Sincerely,
Marius

Hi,
If I were you, I would invest in another network card or a gigabit/USB3 (or C) adapter; the adapter can always come in handy.
I think your card is not very reliable.
I changed the cable connected from my Box to my Switch and the problem is solved!
Thank you for your help!
Hello.
- If you are connected via Ethernet using powerline adapters, it could be the powerline adapters.
- If you are connected via Ethernet with a cable directly linked to the Freebox, go to http://mafreebox.freebox.fr/ and check if the settings for your Ethernet ports are set to automatic; if necessary, choose another setting and see if that changes anything.

A hello, a reply, a thank you are always appreciated.
As mentioned below by Brupala, the best option would be to change the Ethernet network card, since you have a tower you can install a PCI Ethernet card like this one, this card is based on Intel's I225V chip, if you get it here is the link to update it see this page
Hello,
What you're saying is not possible over WiFi... Moreover, we have no characteristics of your hardware and your environment... so we can't say anything coherent... The BOX...? The PC...? type of network card...? test measurements on Nperf...? How many connections in total in the house share your total bandwidth...??? a 1Gb/s connection is not just for you...
The speed is controlled by the server that sends you the file, not by you...
I am wired via Ethernet, not Wi-Fi. My Ethernet cable is connected to a wall Ethernet socket linked to my router. The problem doesn't come from the router because the other wired computer is at 1 Gbps. The issue could be with the cable or my computer (I think it's my computer). Tonight, I will connect a PC to my socket to see if it is at 100 Mbps or 1 Gbps.
There are 2 phones, 1 tablet, 2 desktop computers, and 1 laptop (I haven't had this problem before).
This is not a question of an external server, as shown in my photos; my computer limits the connection to 100 Mbps.
Connection tests never allow me to exceed 100 Mbps (normally my computer limits it). The results fluctuate between 90 and 95 Mbps.
Hi,
especially since what you display is not the actual throughput but simply the information about the throughput that has been negotiated between the two devices.
If it changes, it's because the 1 Gb/s is causing too many errors and therefore the devices renegotiate a lower throughput, which doesn't mean that you will necessarily have that throughput.
See you blux "The fools dare everything.
It's even how we recognize them."
To my knowledge,
transmission errors do not trigger a renegotiation of the rate, I've never noticed that in any case.
It's negotiated once and for all at the connection.
A bad contact can trigger a renegotiation if it causes a loss of connection.
An Ethernet connection is not like a modem on a telephone line ;-)
Absolutely agree with you!
What I meant to say is in response to this sentence:
Here are two photos taken 3 minutes apart (after restarting my computer, sometimes I have 1gbps when I turn it on before losing it all later):
That is to say, there was a negotiation at 1 Gb/s then after reboot, a negotiation at 100 Mb/s, so during the negotiation the second time, the devices figured it wouldn't hold at 1 Gb/s and therefore switched to 100 Mb/s (but I confirm, this only happens once per session, unless you disconnect/reconnect the card).
Is changing a network card trivial?
I mean, you don't have to change the entire motherboard, right? (because I believe the network card is on it, isn't it?)
And so, changing the motherboard would mean formatting the computer?
If it's on the motherboard, then you add a USB adapter, if it's a tower, you can add a PCIe card.
In this case, it's quite trivial, yes, but changing the motherboard is not, that's for sure.
Thank you all! I'm going to look into buying a cheap network card and whatever happens, I'll keep you posted.
Thanks again for all the help provided, I hope it works out!
After installing a new network card, the problem persists...
It’s not the connection, the cables, the network card, or the motherboard,
a technician from materiel.net assured me that it’s due to the Windows drivers, so I will need to reinstall Windows...
No, just the driver, it's the same card as the old one, the old one is on the motherboard, right?
A USB adapter?
Your thing doesn't hold up.
Anyway, it's not Windows that manages the speed negotiation, it's handled by the hardware (network controller); Windows just manages the limit setting provided to the hardware by the driver.
I even think that the driver has no say in it, it must just relay on that.
In your post 25, you say you changed the Ethernet cable, but that is not enough as a check...
Some Ethernet cables do not have all the necessary wires inside, due to cost-cutting or low-cost manufacturing.
So for that, it is essential to verify that these cables have all 8 conductors wired at both ends... You can see the 8 conductors arriving at the RJ45 plug, through the transparent plastic, each with its color.
Personally, I had a case where there were only 3 pairs instead of 4 pairs, and the result was 100 meg instead of 1 gig...
If you bought several cables of this type... You might very well have changed a cable... for another of the same type...? It's very possible.
Here is my contribution...
OK, swap it with that of another PC that works well at 1 gig..
-- For the record, my cable with 3 pairs was provided with the purchase of a device...
/!\ Important Update /!\
I just ran a test by connecting another PC to the Ethernet port that my computer uses and!
The PC is also limited to 100 MBPS after a few minutes.
So the problem comes either from the wall Ethernet socket, the wall cables, the switch, or a port on the Freebox.
If anyone has solutions to find out where the problem lies, please let me know!
I bet it's a faulty wall or patch panel socket,
intermittent faults and bad contacts are complex, the best thing to do is to dismantle and rewire both ends by shifting the impact of the self-stripping contact by about 2 mm, hoping that the bad contact is at the wiring level, not at the socket contacts, in which case, the relevant socket needs to be changed, the issue is knowing which one, you can do it through visual assessment or it will be you who will be the cat....
