Hello,
I have fiber optics but I only receive a speed between 10 and 20 Mbps.
So I bought a 15-meter RJ45 cable connecting my laptop and my box, which are separated by just one room, but I only receive a speed of 9 Mbps...
Could you please help me?
Best regards
Configuration: Windows 7 / Chrome 24.0.1312.57

Bin? The short cable synchronized at only 100 Mbits/s, I was expecting 1 Gbits/s: The fiber Bbox is compatible, the Cat 5e cable is compatible... the issue remains with your PC: Could it be incompatible with Gigabit? Check the settings of its network card...
If the PC is Gigabit: The driver for the card is poorly configured, poorly installed, or not up to date. Otherwise: The 15m ethernet cable is indeed defective.
And you have a second problem as well, to discuss with Bouygues: Your cable signal seems poor, a bit too strong. As if the connection was poorly done, or as if an amplifier was poorly adjusted, or... -
Coaxial cable signal too strong: Signal too powerful, risking saturating the modem's input, which will perform less well, with a risk of transmission errors. This is not at all like ADSL, where the more power there is, the better it is, because it allows for higher speeds. In coaxial-fiber technology, the speed does not vary at all with the signal strength, as long as the power remains within a fairly wide range of proper functioning, neither too strong nor too weak. And your signal is a bit beyond the upper limit.
This is a second problem, which has nothing to do with the first. But both can impact SpeedTest results. It would be better to first address the issue on the Ethernet side, and then reassess the situation. -
Your card is supposed to support Gbit Ethernet. Try updating your network card driver. ;)
Run devmgmt.msc, then right-click on your network card and select Properties. Next, in the Advanced tab, you should have different options, including one that defines the maximum speed. Check that it is set to Auto or the maximum of 1000Mbits/s

So here is the local network connection window:

And here is the detailed cable signal information page:

Sync at only 10 Mbps: Your Ethernet cable is likely faulty, or your network card is misconfigured. Try using another Ethernet cable of category 5e or higher.

Hi!
Show us the image result of a SpeedTest by selecting the Massy server. What speed does the Windows local network connection indicate for synchronization? What model of Bbox fiber: Sensation or not? -
- It's strange, I just bought it from Rue du Commerce!

- So I'm using the cable that came with the Bbox which happens to be cat 5e, otherwise I'd have to buy another one, which is annoying.

Hello
What are the possible values and currently selected for "Auto Disable Gigabit" and "Receive Scale"?

Hello and thank you for your quick response.
Here is the image of my result on the Massy server.

Where can I find the sync speed? :s
I have the Bbox before the Sensation, a white one. -
The Ethernet sync speed is displayed in the status of the local network connection of Seven. On the bottom right, or in the network and sharing center, whatever.
Show us also the detailed cable signal information page (in the administration interface of the Bbox fiber). -
How to know if it is Gigabit compatible?
Or where to find these settings for his network card?
I only know the basics about PCs, this is a bit off track for me :s
Is my cable signal a bit too strong?
What do you mean by strong? -
I looked online and here is the network standard 10/100 Mbps, 10/100/1000 Mbps.
My computer is a Toshiba Satellite A500-14K that I bought 2 or 3 years ago. -

Hello,
Sorry for the delay.
I went to check the graphics card and this is what I found...
Nothing :s

Oh sorry :s
so I have this:

For the first one, I don't have an advanced tab
in the second one I have this:

And for the third one I have this:
https://imagesia.com/gh-_63nv and https://imagesia.com/wfdghj_63nx -
Your wired network card is the 3rd one on the list: Realtek Gigabit Ethernet. Check the "Speed & duplex" option, as well as the options that reduce speed to save energy. Make sure to note the original values before changing anything!

Hello,
Personally, I would start by updating the network card driver.
According to the screenshot, it's this one (choose the correct OS):

9Mbits or 9MB?
Do a speed test and post the result
[EDIT] I just saw the photo...
Hmm, go to the administration page of your box and check the internet speed (which on fiber is between 100 and 150Mbit/s).
Are you going through a switch?
16 ping and 9Mbit/s doesn't really look like a fiber connection... generally, fiber has 2x less ping, 10x more download speed, and 4x more upload speed
(1/9ms - 80-100Mb/s - 8-10Mb/s) generally on fiber...
