DHCP Error; Connection Constantly Lost RRS feed

  • Question

  • Hi all.

    I'm running into a recurring problem: the Internet (broadband and wireless) are going down sporadically. I am connected, but said there is No Internet Access and occasionally, if it does reconnect, I receive a DHCP error after a dialog box prompts me to input "Additional Login Info."

    I'm wondering if this is an error I can see to myself, as contacting my ISP is... laborious as all hell.

    IPv6 is not enabled.

    OS doesn't matter too much, since the error is the same on multiple devices (PC, Mac, Android, Apple), but I'm running on Windows 7 64-bit.

    ASUS RT-AC66U Router and a Thompson DCM476 Modem (rental; can't change this).

    Posting ipconfig to see if there's anything that needs to be set up in there.

    Any help would be great.

  • The configuration looks fine.

    You have mentioned that IPv6 is not enabled but I see some IPv6 IPs. Please check your IPv6 configuration and make sure that nothing is manually set.

    In addition, you may want to try this: https://dirteam.com/paul/2011/06/30/configuring-ipv4-as-default-over-ipv6/

    As you mentioned that the issue is only with one device, this may reflect that something is wrong with your ISP router. Try to reboot it and see if that helps - If not, you need to check with your ISP as they are the ones managing it.

  • Hi  CoryIB,

    1. When the internet is going down, try to connect the internet directly. Use a single device, a laptop will be good, without router or switch. Ensure the incoming line is working good,or you should contact your ISP.

          2.>> Default Gateway . . . . . . . . . : 192.168.1.1

                    DHCP Server . . . . . . . . . . . : 192.168.1.1

                Are you using the Router or Switch to be a DHCP server, if you do ,check the Router or Switch is working appropriate. Try to work with a static IP address, determine that it was caused by  DHCP server or not.

          3. You could performing a network capture ,check where is breaking down.

    Best Regards,

    Cartman
