Connected but no IP address

After connecting to my wireless network (LinkSys 2.4Ghz 802.11b router) for
months without issues, I'm suddenly finding that my laptop (Compaq Presario
R3000 running XP Sp2) can no longer get an IP address. The NIC (Broadcom
802.11b/g WLAN) reports connection to the correct wireless network name,
speed shows 11.0 Mbps and signal strength shows "excellent" but it is unable
to complete the DHCP negotiation with the router and ends up with an APIPA
(169.254.0.0) address. I've updated the driver to the current version
available from HP. Device Manager shows the NIC as functional and I see no
related errors in the system event log. I have three other machines
(desktops) connected to the LinkSys router and all are functioning properly.

Any idea would be appreciated.

Do the following:
go to the command prompt (Start->Run->cmd)
and type: ipconfig /renew

Try the above and it will get an IP address from the DHCP server.

It could be something is mis-configured with the wireless NIC, wireless
router, the wireless on the NIC may be going out, or the wireless on the
router may be going out. If you can connect the laptop with a wire
connection does it get the 169 IP? Is the router properly protected by with
a UPS/AVR device as the router will start going defective if not protected
properly from power fluctuations on the line from household appliances
turning on and off all the time?
