Windows 10: Ethernet Adapter - Lease not renewing automatically

    Ethernet Adapter - Lease not renewing automatically

    For the past month the lease on the Ethernet Adapter has stopped renewing automatically. This means that when the lease expires it has to be renewed manually by running the Network Troubleshooter. It then renews for 24 hours, at the end of which the connection is again terminated.

    I have been associated with computers for most of my adult life and I have not previously seen this behaviour... so this is a new one for me. I would therefore appreciate guidance from a Forum Member who has previously encounted and resolved this issue.

    Hi Tabvla

    While I've not had experience with this particular situation, given its been a day, I would like suggest a couple of items. If you don't want to use them I understand.

    Have you tried Power cycling your router? Next have you tried the Network Reset?

    Start => Settings => Network & internet => Scroll to bottom of right hand side =>Network Reset

    This will cause you to “Forget” your wireless passwords and you may have to reset any VPN or customized communication software if you use.

    Then I would run the following four bolded commands. Use a Command Prompt(admin) or Powershell(admin)
    Do not key in info in brackets, there for your information.

    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)

    Hi Ken

    Thanks for your reply and your suggestions.

    The problem is specific to the Ethernet Adapter on a single PC. Wireless is not affected and other devices connected, by Ethernet, to the same Router are also not affected.

    The Adapter is working perfectly so there is no reason to suspect a hardware problem or a Device Driver problem. The only issue is that the Lease has stopped renewing automatically.

    Okay so resetting things could clear it. You said you run the Network Trouble shooter and if that is the one I'm thinking of it uninstall adapters and re-installs so you get a reset. Your call

    A couple of commands I've had success with in the Command Prompt window are
    ipconfig /release and ipconfig /renew. Note the spaces before the /, has always worked for me.

    Ken and Berton, thanks for your replies and your suggestions. Ken, the "Network Troubleshooter" that I refer to is just the normal Windows Network Troubleshooter. I just click on "Troubleshoot" and it renews the Lease.

    But this is actually a very weird problem. The computer is a W10 PC connecting via a standard Ethernet Adapter to a Router. If, at the time that the Lease must renew, the computer is OFF (Shutdown and OFF at the mains wall socket) the Lease renews automatically, however, if the computer is ON at that time the Lease does not renew.

    Could there be little green men running around in the box...... I am starting to wonder.

    Well apart from the network reset I suggested above along with the four commands not sure what to suggest.

    I would check that the adapter cannot be powered down by the computer, Device Manager, Adapter, Properties, Power Mgmt tab.

    Another item you could try is reserving that IP address, based on the MAC, in your router (was suggested in a google search).

    I know I'm going extreme and I'm not suggesting you do this, just asking. When was the last time this machine was clean installed?

    Some devices have been through so many OS upgrades that maybe little Green men are lurking.
