  • Vista and DHCP

    Question: I have three laptops all connected wirelessly. Two of these work perfectly

    and the ipconfig throws up the exact right info:

    LAPTOP1

    Wireless LAN adapter Wireless Network Connection:

    Connection-specific DNS Suffix . : home
    Description . . . . . . . . . . . : Intel(R) WiFi Link 5100 AGN
    Physical Address. . . . . . . . . : 00-21-5D-B7-B1-0A

    DHCPv6 Client DUID. . . . . . . . : 00-01-00-01-11-63-F1-38-00-1D-BA-87-4D-EE

    The above settings also apply to LAPTOP 2.

    Now when I run ipconfig on LAPTOP3 I get a completely different configuration: I have

    also connected this as wired to see if it made any difference.

    Strange thing is that it is showing up as "connected" to both LAN & wireless, but

    indicates, obviously, that I can only get "Local Access".

    Also, the network defaults back to "Pulic" where I want it to become "Private"

    Any help greatly appreciated





    my network connectivity in vista keeps defaultin back to public & fails to obtain an ip

    address both wired and wireless

    Remove the wireless settings on laptop 3 and try again. Can it connect to other wireless networks ok? What OS does each of the other laptops have?

    Thread moved to Vista forum.

      I had the exact same problem with my PC when I first installed Vista. It might also be worth upgrading the firmware on your router, I think there were some known problems with this issue and Netgear routers.
