ip address not being found upon boot up

Hi,

When my laptop goes into stand by mode it does not pick up an IP address. I
have to reboot. I think there is a conflict between windows amanging my
wireless connections and Intel proset. I have tried going into dos and typed
ipconfig/renew and it an error appears saying it can't renew it. If I try
release it says it has already een released.

How can I ensure the IP address is always picked up? Interestingly, keep a
physical address not IP is just zeros. I am very close to my wireless router.

Thanks

Nathan
