kids wireless gets 169 and won't connect

hi everyone this is the first time i've posted to major geeks so please bare with me. the kids pc downstairs is hooked up using a 802.11g wireless lan mini usb adapter which then connects to a wireless-g adsl router upstairs.
the kids pc is win me. the installed software (zydas ieee 802.11g) works fine and the correct lights are lit on both the adapter and the router. however the pc won't connect to the internet. ie just keeps flickering as if trying to connect but it can't and eventually gives up. the router is dhcp enabled.
i don't get why they are connected but the pc can't use the internet. i have tesco broadband adsl the pc doesn't have a firewall..not that i'm aware of. it did have some security software on ther but i got rid cause the kids mess it up all the time! can't do step 2 like that...this is win me. the network icon in control panel gives me network settings. one is tcp/ip zydas usb. the other tcp/ip is for the other onboard network adaptor which i have now disabled just incase but it's made no difference. if i type winipcfg in command prompt i get this:
