    Unidentified network - No Internet access


    I have two computers running Windows 10 Pro Technical Preview Build 9926. One computer is a desktop and it is working perfectly. The other is a new HP 15-F039WM laptop and it came with Windows 8.1 With Bing installed and it also works perfectly in Windows 8.1 mode. I resized the hard drive on the HP laptop to free up 150Gb of space and then installed Windows 10 TP Build 9926 from DVD. It still works perfectly when I use dual boot to go into Windows 8.1. When I use dual boot to go into Windows 10, the network icon in the system tray says "Unidentified network - No Internet access". I did swap cables, etc, but I knew that wouldn't work because the laptop does have Internet access when booting to Windows 8.1.

    I read through some threads here after searching for DHCP and connectivity issues and even tried some of the suggestions such as using regedit to look at the network profile. There isn't a network profile. It is displaying a 169... IP Address, so I know that it isn't getting an IP. I tried to manually add the correct settings that work for Windows 8.1 (192.168.0.15 with 192.168.0.1 as the Gateway), but that fails.

    Any ideas?

    Try running this batch file to reset the TCP/IP and Winsock stacks.

    TCPIPreset.bat

    IF that doesn't help, try the static address again, but include the following Google public domain name servers
    8.8.8.8
    8.8.4.4

    The subnet mask should auto fill with 255.255.255.0

    Are your sure the subnet for your router is 192.168.0.1

    Check the connection status from the Win8.x side to be sure.

    IP addr: 192.168.0.27
    Subnet mask: 255.255.255.0
    Default gtw: 192.168.0.1

    Pref DNS: 8.8.8.8
    Alt DNS: 8.8.4.4

    If all else fails, power down the router, cable modem (if separate) and PC.
    Power up the PC
    Power up the router, wait 15 seconds
    Power up the cable modem (if separate), wait for it to do it's handshaking with the server and ........

    Bill: I will definitely try your batch file. As for 192.168.0.x, yes, that is correct. I always set my routers to "0" and not "1".

    Update for build 10074


    Here is an update: When build 10074 came out, I formatted the Windows 10 partition and reinstalled from scratch using a verified (by SHA1) ISO burned to DVD and it is still failing with the exact same problem. The good news is that there are many people with my problem, so I will assume that Microsoft will eventually fix it.

    You probably need to download windows update to get the wireless controller driver. Connect your computer temporarily to the internet via ethernet cable.

    Hmmm, I seemed to have left out one bit of information in post# 2
    Try using the values in that post in the alternate configuration.

    Uninstalled Avast = problem solved


    I scoured the internet for hours, resetting wins, tcp, setting a static ip address, etc.

    I uninstalled Avast and rebooted, which did the trick.

    Glad you got it sorted and thank you for posting the resolution. It seems as though there are a few AV products that interfere with Win10 in the preview.

    Don't run naked though, setup Defender as your real-time AV protection until MS or Avast figures out why these things happen.
