    local area network doesn't have a valid ip configuration


    I set up a few days ago a wired connection. (With Wifi we have 30 down/ with the wired connection we have 220 down.)
    I have cat6 running from the router to a hub inside the office and from the hub the cat6 cable connecting to the computer. HP workstation running windows 10 64bit with 32mb memory.

    I turned off wifi - to take advantage of the wired connection. For several days I would run speed test to keep watch on the speed. For several days no lose of connectivity; then suddenly there was no connection with the wire. I had to connect the wifi to get access to the internet.

    However the blue light was on at the router/hub side, and in the office at the hub blue lights on. I then ran the cable directly to the computer. No connection. I keep getting "local area network doesn't have a valid ip configuration' if using the wire.

    I goggled that phase (local area network doesn't have a valid ip configuration) and read many articles. I have ip address to auto; dns to auto.

    I don't know what to do. I did try putting an ip address and Spectrum dns into 'tcp/ip 4' with no results then reverted to auto settings.

    Here I will post IP Config

    Hi parvardigar. Welcome to the TenForums @parvardigar


    Are you running some Virtual machines?

    So you have a router from your supplier and you ran a wire to office. You said hub, is this a router or a switch.

    If a router in office where did you connect wire to router, if the WAN port then you created a new LAN and should ensure it is not using same IP range as ISP router.

    So if ISP is 192.168.3.XXX

    Office router should be handing out addresses is a different range, 192.168.32.xxx


    If the wire from ISP is plugged into one of the general four lan ports you should assign an address to your router (within ISP range but you know won't be duplicated) and shut off DHCP in office router. Let the ISP router assign all addresses.

    Your connection shows three connections, Ethernet, Ethernet 2 and Local connection. You have an invalid IP address, starts with 169, and three valid (???) addresses, 192.168.40.1, 192.168.43.1 and 192.168.1.104. The address ending in 104 is a wireless adapter. I don't use virtual machines but I think I would just reset Network on device once you get wiring straight from ISP to office. You can see all kinds of IP ranges, 192.168.1.xxx, 192.168.40.xxx, 192.168.43.xxx. ( a 1, a 40, and 43)


    Start > Settings > Network and Internet > scroll down right hand side > Network Reset.

    Any specialize comm settings will likely need to be redone, ie, virtual machines and VPN's.

    Your getting a 169 range IP which means DHCP isn't working if it's a hub they are very dodgy as they blast data across all ports unlike a switch. As a quick fix you could set a static IP
