    dhcp works . static ip doesn't


    If I set my computer to dhcp I can get access to the router and to the internet just fine. If I go into the control panel and set it to static IP then I can't get access to anything.

    Here are the steps I am taking:
    In the Network and Sharing center window
    I click on: Change adapter settings (In the left hand side of the window)

    That gives me the Network Connections window
    now I right click on "Ethernet" and scroll to the bottom and choose Properties

    Now I get the Ethernet Properties window
    Scrolling down to TCP/IPv4 I click that and then select properties

    That gives me the Properties window (yes I know I am being detailed.. but windows 8 is new .. and maybe I am just doing something .. dumb)
    Now I fill in the 5 fields in that window "Ip address" "subnet Mask" "default gateway" "preferred DNS server" "alternate DNS server" ..

    then I hit ok on that window and ok on the previous window also.

    At this point the "network connections window" shows my Ethernet icon and it says "network" below where it says "Ethernet" ..

    and I have internet access for about 30 seconds. then I loose internet access . if I try a reboot .. the network icon in the system tray tells me it can't find a network.

    is there something that I am missing?

    I have windows 8 pro
    I was able to have a static ip address when this same computer was running windows vista 64 bit. all I did was remove vista and put in windows 8 pro. the router stayed the same.

    I'd have to see the settings you were trying to use.

    ip address 192.168.1.103
    255.255.255.0
    192.168.1.1

    can't remember what the dns entries were, but I got them from the router (and the router acquired them from the cable modem) which is how I always found the dns entries in the past.

    Can you set it back to dhcp and give us a screenshot of an ipconfig? (cmd-> ipconfig /all)

    It could be a whole different range.

    Usually when this happens the static entries aren't compatible with the subnet that the router is using.

    So it would help to see the ipconfig/all with DHCP enabled to see what parameters the router is using for DHCP.

    Basically what I was saying.

    I'm a bit worried about your DNS settings though, could you set the first DNS to 192.168.1.1 and leave the second one blank or fill it with 8.8.8.8 (Google's DNS)

    That is, if you are 100% sure 192.168.1.x is the right range..

    Your settings should be like this:

    IP addres: 192.168.1.103
    Subnet Mask: 255.255.255.0
    Default Gateway: 192.168.1.1

    Preferred DNS server: 192.168.1.1
    Alternative DNS server: blank / 8.8.8.8 /8.8.4.4

    Its been my experience that when setting up a static IP address that you don't want to use one that is in the DHCP scope of the router. So lets say your router is giving out IP addresses in the range of 192.168.1.100 to 192.168.1.199. In this case I would use 192.168.1.99 or lower. You can't have two PC's with the same IP address on your LAN. If you use 192.168.1.103 and the router gives it out to another PC you'll loose your connection. Also I do believe setting your DNS server info to the routers IP, 192.168.1.1 only works if DNS Forward is enabled in the router. It should be by default, but you might want to check it to make sure.

    You are right, but any decent router should see that an ip is taken nowadays. I can hardly believe there is an IP conflict. Again, to be sure of all of this, open up CMD and run 'ipconfig /all' and post the results here.

    I was commenting on the reply I received, my comment had nothing to do with your post.

    Routers, even decent ones, do not see a distinction between static IP's and DHCP IP's, they will bump the static IP's offline in order to give out an unused DHCP IP. Maybe the IP is already in use because the static IP wasn't outside the range of DHCP or it could be something else.

    If the static IP's aren't outside the range of DHCP then there may be an IP conflict, happens all the time and most people aren't aware of it. Just fixed one last week because the static IP's weren't outside the DHCP range.

    I totally agree with you, but since the range is 192.168.1.x I'm assuming there are not many pc's on the network. so it would be a very strange coincidence.

    (192.168.1.x is very typical for routers that are found in homes that don't have much pc's connected)
