    W10 Anniversary update - can't get ethernet at 1Gbps gives 100Mbps


    Hi there

    My Lan connection seems to report 100Mbps (Ethernet) instead of 1Gbps. This is after upgrade to new W10 anniversary edition.

    W10 Anniversary update - can't get ethernet at 1Gbps gives 100Mbps-network.png

    My Laptop wifi can do better at 400 Mbps !!!!

    Cheers

    Its working for me, I see 1Gbps. Have you configured the nic card's speed settings?

    It's probably replaced with MS generic LAN driver? Try reinstalling the driver.

    I tried different cables uninstalling and reinstalling drivers. Its on both my Nics running at 100mbs and I have a NUC that does the same with Anniversary. I have one PC that has not updated yet and that runs at 1000 mbps I put that cable into my NUC and it will still run 100mbps?

    I do think it's a bug with windows 10 Anniversary Update as it happens the same with 100Mbits, it only shows as 10 mbits, but the problem while it's not fixed by Microsoft can be fixed like this:

    - Go to Network and Sharing Centre,
    - click in the Ethernet,
    - then Properties, Configure, Advanced,
    then in Energy Efficient Ethernet you have to make it Value: Disabled.

    It solves the problem in my case, hope it solves yours also, someone than has the Microsoft call number inform them please!

    If you are sure you had 1Gig prior to the update it might be a few different things that caused this. Some stuff I can't remember exactly I had to change last July when 10 came out.

    Go to the actual driver from Device Manager. Aside from making sure you have the right driver that's not generic. Go to details/advanced and make sure everything is ok (Bandwidth Capability, etc, some are different in the wireless driver vs the Ethernet driver)

    Allover windows 10 and anniversary there are various settings everywhere that change things on our PC's that we wouldn't expect. Windows out of the box/factory settings is setup for maximum battery life and that normal just use a PC to Google and read email and that's it. If that makes sense. Its all easy stuff but its gonna take some research and discovery to get it correct. Aside from your internet settings. Also check to make sure you don't have anything set to "metered connection/internet". When I went to this upgrade about 2-3 weeks ago as a Insider I found out its basically a new OS. Most people I think kinda assume the "skin" of a OS is what makes it a update vs upgrade but anniversary has changed a lot just a lot of it is that invisible stuff. In my eyes it was like going from Windows 8.1 to 10. Win 10 to Anniversary was the same to me. Especially how well RAM is managed and start up and so on. Go into power settings and just make sure Ethernet and Wireless aren't set to power management battery saving. I think with Windows having 2 sets up Settings the new and the old some of this stuff is getting screwy in the system. I was trying to fix Bluetooth that seems to be non existent but in the process I lost wifi too and with no luck.
