D link G122 problem ( Pc and Mac)

I am using Dlink G122 wireless adapter and Dlink 624 router. I have two
notebook and one Mac G4 computer. The first notebook have build in
wirless card and work fine with the router, it can obtain the IP
address automatically ( IP : 192.168.0.100 submask : 255.255.255.0,
Default gateway :192.168.0.1, DNS: 192.168.0.1)

The second notbook with Dlink G122 and it doesnt work with the router,
It sits at
"Obtaining IP address" for about 2 minutes until it times out, where
it delivers an IP address of 169.254.xxx.xxx and announces that you
have "limited connectivity". It can't brower any web site.

The Mac G4 also with Dlink G122 and it have wireless connection but
also can;t brower any web site..


On the admin page of router setting , it show the range of Ip between
192.168.0.100 - 1XX

Is the IP problem or the range of signal.?

Plese help and suggest any reason ?

Try setting the gateway manually to 192.168.0.1, it should then get IP
address.
Failing that set all computers manually with static IPs.
