Increase upload speed Solved

Question

Hello,
I would like to know how to increase my upload speed. I am with SFR and I have fiber optics with 100mb/s download and 5mb/s upload. When I go into the Box configuration, I can see that my maximum download limit set by the box is 100mb/s, and the upload is 5mb/s. On my speed test, I am at 95mb/s for download and 4.3mb/s for upload. Of course, it's not adjustable since an offer with a higher download speed costs more, but I haven't seen anything about the upload. My PC is connected via RJ45 (5m cable, cat 5e). Do I just need to call SFR to increase my upload speed, do I need a different, more expensive plan? Or something else?

Thank you in advance.

You will always have an upload speed that is lower than the download speed; that's the principle of ADSL...
To have identical speeds (and even then it's not guaranteed), you need to switch to SDSL.

There's Orange that offers this for fiber, or SFR "Business", but they are very expensive... and it seems that for both providers, this option is reserved for professionals.

Hello,

Rather a Coaxial offer at 100/5... However, there's no way to increase the upload. Especially since the offers are based on average usage and the expected use of the subscription.

As mentioned before, one has to switch to SDSL to get symmetrical speed, but this type of connection is rarely offered to individuals. As for fiber offers, those with guaranteed upload speeds are relatively expensive and often also reserved for professionals.

For example, at SFR, the "Connect Fibre" offers that provide guaranteed speeds start at €300 excluding tax for a symmetrical speed of 10Mbps. One can reach over €1000 per month for a symmetrical speed of 100Mbps.

Only Free and Orange offer higher upload speeds, provided you are on a real optical fiber (FTTH) and not a coaxial connection (FFTLA) which you seem to have at SFR.

Hi,
already at those speeds, you don't have real fiber, but coaxial termination (shared network with your neighbors).
In theory, real fiber allows for symmetrical speeds like SDSL, but stronger.
Typically, SDSL is 2 Mbps or 5 Mbps over a telephone pair in g.shdsl bis version and about 20 Mbps by coupling 4 pairs.
On a single point-to-point fiber, you can have 1 Gbps in each direction for consumer connections, but it can go much higher.
Fiber on gpon also provides asymmetric speeds, but with less difference: around 400/100 Mbps, an average ratio of 1/4.
In your case, SFR can change the speed within a certain limit, but beyond that, they have to change the whole area.
This article is a bit dated, but it explains well the contradictions of SFR in this field.

Alright, thank you for your responses.

I will stay like this because I don't need a good upload speed enough to carry out the procedures. I’m actually not complaining about my connection; it is always fast and stable. And even for the upload, I was just asking for that to save time because considering what I upload, time isn’t an issue for me; it was just to optimize, nothing more.
