  1. Intel LAN Driver not handling 1GBps


    So i figured out that the driver software itself handles the Network Speed of the card. So as i recently had the problem with the speed going all the way down to 10MBps, i found in the driver settings it can auto regulate between that. I then set it to 1GBps, but it doesnt seem to accept it and instead it cancels my internet connection, while 100MBps Full Duplex works just fine, what is wrong?

    Here two screenshots:
    1GBps without internet:

    100MBps with internet:

    Thanks for the help in advance *Smile

  2. Difficult BSOD

    Update the Intel Lan driver to version 20.2.4001.0:

    You have a TP Link wireless adapter. What model?

  3. Fresh install of Windows 10 gets update error 0x8024401c

    Nope, no proxy. Clean install of Windows using default settings. The only thing done after Windows was installed was to install the chipset/video/sound/Intel RST/ME/LAN drivers.

    Just wondering if this is an issue with the Intel LAN driver (which was installed over whatever default shipped with Windows 10) or if this is an issue with Windows.

    I'll probably try doing another clean install tonight and not install the Intel LAN driver, to see if that's the problem.

    Not that i forget to mention it, but it sometimes when i switch over to its default (Automatic Detection), it sometimes also doesnt have Internet, and when i switch back to 100MBps Full Duplex, i still dont have internet, if i do that again the same way, i then get internet (or not, depends), but i never get internet on 1GBps, i sometimes have to unplug the cable (Cat6) to get internet back. What is wrong here? Could it be the wall mount wich is Cat5 (not Cat5e)? (But i am sure it cant be, since Cat5 can also handle Gigabit, so this is odd...).

    Have you ever had solid 1gb connection there before? Cheaper Cat5 cable and even just having cheap plugs on the cable ends will not allow 1gb.

    I ran cable across my basement to give me a 1gb connection in another room. I first used cheap Cat 5 cable from EBay. First I discovered that not even a 6' length of that cable would give me 1gb through it. So I got some real Cat 6 cable from Home Depot. Still using the cheap plugs and crimper from Ebay - nope - no 1gb. Went back to Home Depot and got real Cat 6 plugs. 100% solid 1gb connection now.

    Also.... try going back to the Windows 8 driver offered by the manufacturer of the Network Adapter. I had to do that with Realtek PCIe GBE Family controller to get all the functions working. Had to extract the drivers and use the Update Driver, Browse my computer, let me pick my hardware, have disk method to force the older driver to load.

  7. Well ye i already tried that, with the Intel Driver its easy, uninstall and install the 8.1 driver. The problem is, the wall socket is Cat5, and the Cable is Cat6, the cable is a really good one, and even if it wouldnt deliver 1GBps, it should still give me 100MBps on the 1GBps option, because just if i cannot get 1GBps, it shouldnt stop it from accepting 100MBps.

    I was led to believe that Cat 5 wasn't able to do gigabit. You need either 5e or 6 for full speed. Whats your setup at the router end is everything capable of gigabit?

    And even then - the stuff from China advertised as Cat 5e won't even come close to doing gigabit!

    Until I got good cable and connectors, my lan adapter would not go into gigabit mode. The lan adapter senses what the network is capable of and adjusts its mode to match. This screen would only show 100mbps:

  10. Everything here is Gigabit capable yes. But the thing is, i am forcing it to 1GBps, but why is it adjusting itself down to 100MBps? I mean it could be the wall socket wich is Cat5, i can try to buy a Cat6 wall socket in the next days and try to mount that.

    Do you have two devices that are gigabit that you can connect together with a known good Cat 6 gigabit cable? If it is two computers, you will need a crossover cable. A router or a switch will just need the regular cable. Connect two gigabit devices together with a known good CAT 6 cable and see if a 1 Gbps connection is established.

    If just one connection - such as the wall outlet - is bad, it will drop to 100 mbps. For simplicity in my house, I just used wall plates with a hole in them and have 6' of cable poked through the hole with a good connector on the end. The data connection to me is more important than looks Intel LAN Driver not handling 1GBps :).

    Hi there

    can you NETWORK between two machines at 1GB - without the internet working but still going through your router (just disconnect from the Internet).

    If you can't get a LAN connection of 1GB then you won't get an Internet connection of that speed.

    If you DO - can you plug a computer DIRECTLY into your router / cable and check Internet speed.

    Note also writing to slow HDD's will give a false indication of speed anyway - I can't think of any home grade computer with consumer grade HDD's that will give you a constant data transfer of 1GB/s anyway. Some SSD's might - but the chances are the MOBO's bus speeds will be of at least an order of magnitude slower.


    Cheers
