Network card stuck at 100 Mbps

Solved

Hello,

I have an ACER Nitro AN517-51 i7 that is advertised with a Realtek Gaming Family controller 10/100/1000 network card. I am currently with the provider Nordnet with a connection of up to 1Gb/s. When I perform internet speed tests, I never reach more than 95 Mbps for both upload and download. I am using a wired connection with a 15-meter Cat 7 SSTP cable. I have tried changing my network card settings to full duplex 1Gb/s, but it remains at 100 Mbps. Is the problem coming from my internet provider, my network card, or is it something else? Thank you for your help.

Configuration: Windows / Edge 18.18363

    Hello,

    There is missing information here...

    -> Your "Nordnet" router also has Gbps ports (10/100/1000), right?
    -> Your cable is a direct connection between you and the router (no powerline adapter, no wall socket, no switch, etc.)?
    -> The cable you are using has a GG45 or RJ45 connector? If it's a good Cat7, it should be GG45...
    -> Your PC, when the cable is connected, detects connectivity at 10/100, is that correct? This means that the negotiation between the PC and the router does not go beyond that. Why? Look at the different reasons by answering the previous questions to identify the possible leads...

    Hello,
    Thank you for raising these questions. I downloaded a tool from the REALTEK site that allows me to audit my card and network. This little program indicates a problem with the 'cable'. Based on your questions Judge_DT, I started from the source. At the router, I have 10/100/1000, and the cable is indeed a Cat 7; however, the cable is between two RJ45 wall sockets to make it neater. When I connect directly to the router, as if by magic, my card goes to 1Gb/s. In conclusion, as you pointed out Judge, my issue comes from my RJ45 wall sockets, which I thought were Cat6. I will review my connections behind the sockets; I must have missed something while making my connections. However, when doing a speed test directly at the router, I’m now getting about 700 Mbps down, but I’m still capped between 70 and 90 Mbps up. How can I improve this? In any case, thank you for your help. (Every detail counts, after all.)

      On the other hand, I'm capped between 70 and 90 for upload, how can I improve that?

      We need to check what the subscription provides for the upload first. That said, if it caps at the box... it must be the operator's network that is congested and/or the limit of the plan. It's already quite good to have 90 Mbps upload for a residential connection.

        Indeed, my contract provides for an upgrade from 10 Mbps to 1 Gbps, but I will ask them the question because in the end, they sell you a fiber connection with a lot of Gbps, but in principle, you are well below that. Yes, I know 90 Mbps is not bad, but when you choose and pay for the 1 Gbps offer, you expect it, because in the end, you are just throwing away 10€/month. But it's not the end of the world. Anyway, thank you for your help and time.

        Indeed, my contract provides for an upgrade from 10 Mbps to 1 Gbps, but I will ask them because ultimately they sell you a fiber connection at a high speed of Gbps but in principle you are well below that. Yes, I know 90 Mbps is not bad, but when you choose and pay for the 1 Gbps offer, you expect it because in the end you have 10€/month wasted. But there's no cause for alarm. Anyway, thank you for your help and time.

        You are paying for 1 Gbps downstream, surely not upstream... Firstly, because 1 Gbps upstream, few operators do it and it's not profitable for them, otherwise it saturates the network and competes with professional offers intended for heavier/bigger/consumable usage. Not to mention the fact that these are "best effort" and not guaranteed speeds... ;-))

    Good evening,
    Test with another cable?
    And another PC if you have one, on the 15-meter cable?
