    Hello I have a question. I was looking for a bit of google but I did not find anything specific. My question is, I have an allegedly 120mb / s Internet connection. I have a LAN connection and I write that the connection speed is 100Mb / s. Is this the maximum speed that will flow through my card? I will add that on speedtests I have 94-95mbps. greetings

    Well, then 94-95 is probably the limit of your card's ability, buy yourself the simplest card working in 1Gbps.
    One more thing, what are you using this computer for? To any router / modem? Toss a model.

    Yes, it's the maximum speed.
    The reason why Speedtest shows 94-95 is that when the data wants to exceed 100mbps, the packets are queued and in the case of exceeding the queue size simply thrown away.

    post is in the "Wifi" group.
    If you're actually talking about a copper cable, speed is a derivative
    a) both sides of the link, i.e. the network card and switch (on the principle of the "lowest common denominator"). Limited 100mbit network cards are from the age of dinosaurs. The fairy tells you that the switch limits you.
    b) cabling quality.
    c) settings
    In the wiring of dubious quality, I often limit the speed to 100mbit, I prefer to have a stable 100, than 1Gb with humor and spells.


    EDIT, of course, still words from the borderline of marketing providers, the transmission has mark-ups, firstly, secondly, written in papers, etc ... kilo / mega / giga in binary terms is 1024, 1048576, 1073741824, in decimal 1000, 10000000, guess which use marketers

    you can not confuse megabits with mega bytes. Theoretically, the speed of the card should almost always exceed the speed of the net. On the test it will also not work out and how else because someone set a limiter for you - like the 120Mb. Now 120Mb it is equal to 15 MB in megabytes (mega bytes or in what we operate on a hard disk on a CD or pens.

    Ok, thank you for the numerous explanation of the topic. And is someone able to give me the possible reason why my card works in 100Mbps mode? I have an Intel (R) 82579LM Gigabit and I write on the Intel website that Data Rate Per Port 1 Gbps. So from where 100mb / s.

    I have an optical fiber that goes to a fiber optic center. There are 4 LAN-type inputs. The fitter said that there are two cable TV and 2 internet. So one thing goes to the PC and the other to the wifi router 3 for television and one is free. I will add that it does not matter if the router turned on and the television works, the result is always the same 94-95mbps

    I will add that the cable going from the control panel to my pc on which the tests are carried out is about 5 meters long and has already been in one place, the insulation is peeled off, no copper is used, copper is unmachined, only external insulation of wires is used) .

    Which cable router does the computer not have 5 categories?
    I had at my place so that the 5c dropped the transfer to 100mb I exchanged and I have peace.
    Start with the cable without downloading the data I have 1Gb speed,

    The cable that goes from the fiber optic center to my pc. The wifi router has a connection with the fiber optic center with a separate cable. I will add that I do not have a computer from the period of windows XP. It is a computer with intel i5, 8gb ramu, and I have an annual disk that reaches in hdd tune over 100mb / s so there is no way that the computer blocks me

    I am writing about the cable you described as damaged.
    As you highlight the connection and everything ok, I have no right to be 100mb

    Ok, I'll try tomorrow, move the pc to the room where I have fiber optic and connect the pc with a short cable that I once got along with the router and see if it will actually be 1gbps

    Specify the terms "fiber optic center", "wifi router" - device models. You should start with this.
  • Level 22  
    View the router or the options on the network adapter if you have the 1 Gbit option enabled.

    Connect to the cable you have connected the router and compare. Maybe you have 1Gbps disabled in the network adapter configuration. Well, what is this "fiber center", what exactly do you mean? Because you do not live in a telecommunication closet :D

    Subject resolved. Ricoh_220 very well diagnosed the problem. After connecting with another cable, the test starts at 400Mbps :O but it drops to 130-140 and that's the speed. On an old cable, each result is 95Mbps. And the most important thing on the new cable is 1Gb / s

    Score on the old cable

    The result on the new one

    One more question about which cable to invest. Screened? And what type

    You say "invest" ...
    you have a more important question: rigid cable terminated with sockets, or "holy sacred" with crimping plugs?

    Of course, it's a good cable for a good company, not crimping the ends


    / EDIT

    Which one will be better CAT 5E or CAT 6? Or maybe another one

    In the previous post you write that it is about the next room. A slight inaccuracy.
    Cables on the market have up to 15m, but in the past respected standards spoke about max 5m flexible end-cable (ie recognized network companies should not have more)

    I need 10 meters and it will be with the supply.

    I'm thinking about it

    Is it just a "known company" ... just a typical cable on the market.
    How will you walk the wall?

    The topic for closure got all the necessary information.

    Thank you again for Ricoh_220 for solving the problem
