    Takes long time to connect. Sometimes times out. IE11, Chrome, Edge
    Ping www sites from cmd times out
    Ping OK

    Onle Defender is on. Disabled and still problem

    All drivers updated, Lenovo System Check OK

    Hi Pete.

    Maybe start with powering off router, wait 20 secs, power on, test.

    Then reset of Network, Start=>settings=>Network and Internet=> scroll down right hand side, Reset network.

    Run these four commands to a command prompt(admin). Don't type in stuff in brackets, information for you.

    ipconfig /flushdns (Clear the dns cache)
    nbtstat -RR (release and refesh NetBIOS names)
    netsh int ip reset (reset ip settings)
    netsh winsock reset (Reset Winsock Catalog)


    Next you could try disabling IPv6

    Next I would suspect driver although you said this happen on wired and wireless. Head to lenovo site and get wireless driver. Yes it may be older. Check version currently installed in device manager, install old driver, check version again. If it works for a while and stops, check driver version again in device manager, Windows may have updated.

    Hi Ken,
    Had run the netsh commands already.

    Here's what I just did:
    Cleaned 6 WAN Miniports
    Cleared ip6 out of both adapters.
    After reboot and an update,, PC now blazing fast as it should, 6GB memory.
    Since this was running the same at both clients office and my shop, and is now running as should in both locations, the problem is fixed but I'm not sure what did it.
    I remember a while back, disabling ip6 when it was first added but haven't had that problem recently.
    Maybe it was the WAN Miniports?
    Have set up a number of these Lenovo Ideapads since BestBuy has been offering them at a ridiculous price, $279, Icorei3, 6GB and 1 TB and this is the first one I've had a problem with.

    Thanks for your input, maybe one of your suggestions did it.:)

    Great Pete.

    Not sure why all the issues around IPv6 and maybe it wasn't it. Is there something in the Windows implementation that is conflicting with the existing (older) router base or is some bleeding edge protocol withing IPv6 causing issues. Maybe its router firmware.

    It is quickly becoming my go to "try this".

    That said I understand IPv6 is used by Windows Homegroup which can jam up some users. They want / need Homegroup and they want / need their Internet.

    Thanks posting back your solution and marking thread solved, others will find.

    Should have said this was slow at a client's residence and slow at my shop. Comcast cable but 2 different style gateways.

    Also, when I just returned the PC, the owner told me it was never quick loading like it is now since she bought it a month ago.
    Anyway, the post remains hopefully to help others. Maybe even Brink?
