Wireless Network no DHCP

I have a Sony Vaio laptop running XP pro with SP2, and a US robotics wireless adapter. In the office a belkin wireless access point. Other wireless machines can connect to network fine.
Now windows XP detects the wireless network fOK, shows signal strength as excellent, and shows a status of 'connected'. However a DHCP lease is not obtained. Trying to renew the lease results in the error 'dhcp server could not be contacted...'. Have tried assigning a static IP, but cannot ping the access point.
Have also tried 'repair' of connection, deleting and re-creating the connection, uninstalling and reinstalling the wireless adapter drivers. All to no avail.
Everything is hunky dory when the machine is connected to the wired network.

Any advice on this would be most appreciated.

It sounds as if the nic isnt really conencting... are you sure that it is the right letters?

Otherwise, I think that the subnets arent the same. Check that on the IP as well, if you are doing static addressing

Anywahy, I know it shouldnt be brand dependant. Have you tried the nic from another machine, and vice versa? That could pinpoint it to the card or the PC

Check to see if the Belkin AP is filtering by MAC addresses. You may need to add yours. Also, you don't mention anything about security. Is the office using WEP, or WPA?

Re-seting the router wouldn't hurt. Also I thought most wireless routers only supported 2 wireless connections. Go release an ip off the other machine and then try to renew again on the sony. Yeah, I bet those 2 little antenna's only support one signal a piece. Although I may be wrong. If Im right, your gonna haft to add another access point to the network. If all else fails, when in doubt swap it out!

Thank you all for your advice.
However I have not made any progress.
When trying to get this to work, I have disabled all security features. There is no MAC filtering. Have restarted AP many times. Have updated firmware in AP. There is no difference in the behaviour whether or not the other client is connected. However according to the manual it can support up to 32 simultaneous users.
Further advice would be most welcome.
