Wireless access problem - No default gateway

    Hi I have a laptop and up until recently I was able to access any wireless networks without any problem but now for some reason it just stopped working & I can't access any.

    I can connect to the wireless in collage.
    I can get a "Very Good" connection at 54.0Mbps.
    I have DHCP enabled and auto configuration enabled.
    IP & DNS server are both configured to obtain addresses automatically.

    When I look under connection status my
    IP Address is : 169.254.63.10
    Subnet Mask : 255.255.0.0
    Default Gateway is now blank & this is where the problem is.

    I cannot get a default gateway so I am unable to connect to the internet.
    Packets are being sent out but nothing is being received.

    I've tried ipconfig /release & ipconfig /renew but I keep getting the same reply : "unable to contact your DHCP server".

    I'm all out of ideas so any help is much appreciated,
    cheers,
    Bruce Fan.

    Never mind I got it sorted.
    I just changed the Network Authentication under Wireless Network Properties from Open to Shared. That did the trick.

    under conditions like above its good to know that the 169.whatever address was given to the laptop/pc by itself ie : it has no connection to the "gateway device" or the gateway device didn't give it an address




    Why does it do this : For when you are trekking across the Antarctic and there is no internet Ireland and there is no internet ( access points ) , you want to swap photos with someone you meet who happens to have a laptop too. The two laptops will have to work out a connection between them all by themselves.

    I think the router has to have UPnP enabled to broadcast itself as a default gateway.

    No need usually

    Among a few more things DHCP will give the PC

    An address for itself eg: 192.168.1.100

    A Subnet Mask eg: 255.255.255.0

    A Default Gateway eg: 192.168.1.254



    Default Gateway (usually) = the next device on the way to the internet = (usually) your Eircom/BT/whoever router



    ( above might be handy for someone , someday )
