    All browsers hang after Creators Update


    My PC was working flawlessly before Windows 10 Creators Update. A week or two after the update, my default browser (Opera) started to hang when loading a webpage and says "Not Responding" quite often. While letting the browser in the "Not Responding" state, I opened Edge, Chrome, Firefox, IE to check, but they all can't load any webpage and eventually hang all.

    I tried ping and nslookup, they seem to work from command line.

    Curiously enough, I am using a Wi-Fi connection and, if I disable the Wi-Fi network adapter, all the browsers come alive again instantly and say "The page cannot be displayed", which is normal. If I reconnect to Wi-Fi, all work great until the same thing happens again. Hang, disconnect wi-fi, works perfect, connect again and the cycle repeats.

    I tried to uninstall the Intel Wi-Fi driver and reinstalled it, but the problem persists.
    Any suggestion you can give me? This drives me nuts.

    Note that the network shares (from Windows Explorer), ping, traceroute, nslookup all work fine. Only ALL browsers hang until I mess with the Wi-Fi adapter. It doesn't matter which browser I use.
    When using LAN cable, I couldn't observe any issue, but I haven't tested much (a couple of hours).

    Other thing to note: It seems that other services (OneDrive, Nvidia updater, Steam) cannot connect during this phase, which is weird.

    For starters, have you tried Network Reset?

    I have solved my WiFi problems by simply disabling everything, which is supposed to improve internet.

    To disable "IPv6/LMHOSTS Lookup/NetBIOS over TCP/IP", run CMD as admin and copy/paste:
    netsh int ipv6 isatap set state disabled
    netsh int teredo set state disabled
    netsh interface ipv6 6to4 set state state=disabled undoonstop=disabled
    reg add "HKLM\System\CurrentControlSet\Services\Tcpip6\Parameters" /v "DisabledComponents" /t REG_DWORD /d "255" /f
    reg add "HKLM\System\CurrentControlSet\Services\NetBT\Parameters" /v "EnableLMHOSTS" /t REG_DWORD /d "0" /f
    wmic nicconfig where TcpipNetbiosOptions=0 call SetTcpipNetbios 2
    wmic nicconfig where TcpipNetbiosOptions=1 call SetTcpipNetbios 2
    Then uninstall all network protocols from network adapter except IPv4 and uncheck IPv6, like this:

    Haven't tried. I just uninstalled manually the adapter in Control panel and then used the Intel software to reinstall.

    What does "IPv6/LMHOSTS Lookup/NetBIOS over TCP/IP" really do?

    I do use IPv6. Do I have to uncheck it?

    IPv6 is usually the main cause of problems.

    LMHOSTS Lookup/NetBIOS over TCP/IP are needed, if you use aDSL or use file sharing within a network.

    Ok, so it seems that I shouldn't disable LMHOSTS Lookup since my networks relies on network shares from different windows PCs.

    I will disable IPv6 and try it out in IPv4 only, but my other 4 PCs work fine with the same IPv6 IPv4 coexistence, all running Windows 10, but different network adapters. I don't know why this is the only one on which browsers hang.

    In that case try looking for a newer driver, maybe that one just is not compatible with CU.

    Driver Easy Free is good in finding drivers.

    Hm... Just found another similar thread on intel's forums: Intel dual band 7260AC for desktop hangs on Win... |Intel Communities
    Maybe a driver issue? I will try an older version instead a newer one.
