    No Internet with Static IP


    Hi everyone. Hope you can help. I ahve a number of windows 7 pro 64 bit computers. I have configured them with static IP addresses. None of them can get internet. I can ping other machines on the network and vice versa but cannot ping the router. If I configure an xp machine with these details then internet works fine. It Appears that the windows 7 machine only wants to work with dhcp. I have another domain running dhcp with a different set of ip credentials. Any help would be much apreciated as I have tried lots of solutions like disabling IPv6, removing and reinstalling adapter flushing dns and so forth.

    Welcome to the Seven Forums.

    Please post the IPCONFIG info for one of the W7 computers while it is assigned a IP via DHCP.

    Then post the IPCONFIG info for the same W7 computer while it is assigned a static IP.

    Hi wevy69, Welcome to Sevenforums.

    If you're setting up a static address you also have to manually configure your Gateway and DNS server(s). Try plugging in the address of your router for these.

    Make sure your PC and router are on the same subnet as well.

    For example, your router has an address of 192.168.1.1 with a netmask of 255.255.255.0 and your PC has an address of 192.168.2.1 also with a netmask of 255.255.255.0. This puts your PC on a different subnet than your router and they won't be able to communicate regardless of your Gateway and DNS settings. In this case you would either change the netmask of both to include each other's subnets (255.255.0.0 for instance) or give the PC an address of 192.168.1.xxx to match the router's subnet.

    As mentioned i have also used the static details on an xp machine and this works fine. These win 7 machines are to replace all of the xp machines that are using static IP's at the moment. The addresses I am using are not already used on the network as this has been checked.

    We will have to see if other forum members see where the problem is - I don't see it.

    Is there a reason why you use two different reserved private IPv4 ranges, 10.12.X.X for DHCP and 172.16.X.X for static? If the router is the same with same settings on both examples, I mean if the router's IP is not changed it being 10.12.X.X while PCs are looking a default gateway at 172.16.X.X, it seems IMO logical that there's no internet connection.

    As already mentioned and now pointed by Kari as well, PC and router should have same DNS and subnet group for them to communicate.

    I'm guessing that the router is of commercial grade. It has multiple VLANs setup.

    My office uses 10... and 172... IP ranges too.

    Like the OP said...
    ...the XP boxes work using the 172.16.... static setups
    ...the W7 boxes don't.

    That's why I asked if there's a reason for using different IP ranges.
