    Guys,

    I just recently reformated my laptop into windows 7, details below.

    Processor: Genuine Intel(R) CPU
    RAM: 512mb
    System Type: 32 bit OS
    Ethernet Driver: Realtek RTL8139/810x Family Fast Ethernet NIC
    with driver version 6.111.723.2009

    I have no problems with my wireless, but when I try to connect to my LAN, for some unknown reason, my laptop cannot obtain IP. DHCP is enabled. I also tried to acquire using cmd. ipconfig /release then ipconfig /renew. I still get the 169.254.126.96 ip.

    any help will be appreciated.

    Edit: Static assignment works fine, the only issue is DHCP. Router is working fine, I tried connecting it to my other laptop using xp and vista, they obtain ips exept win7.\

    thanks

    Check if any firmware upgrades are available for your router?

    @Camusing,

    I know what my IP is, the problem is about obtaining IP..

    @lookingAround
    Ive been using different routers and problem still persist.

    I tried reading to other forums, but the problem is still not resolved. I hope someone could help me out.

    the 169.x.x.x address is the clue. this says that you could not access the router's DHCP
    service and the NIC generated that address.

    You should have used the Win/7 Network Wizard to create the connection and chosen
    the Private networking option. This would configure the Firewall properly.

    If all else fails, you can add FW rules like this:
    allow tcp/upd in/out srcip=any destip=any ports 67-68
    The actual syntax for win/7 should be easily derived,
    but the above is a generic statement of the rule.
