I need assistance with the following issue:

Scenario: Windows XP Pro with Netgear WG111 USB 2.0 wireless(wifi)
adapter. Drivers and applications installed from latest zip file from
netgear (wg111_2_1.zip). Native netgear apps not running at all,
instead I am using Windows XP's capabilities to manage my wifi network
which consist of an ad hoc network with desktop as host and a laptop as
the client. I am using Win XP's Internet Connection Sharing (and its
DHCP capabilities).
The ad hoc network runs at 11 mpbs (802.11b) and has a wep key.
For 2 weeks everything works fine. Win XP assigns an IP address to the
laptop everytime it connects to the ad hoc network, and I can use my
broadband internet connection from my laptop. All is good. Getting
great range and data transfer rate is great when streaming music from
the host desktop.
Then for what seems like totally out of the blue, Win XP does NOT
assign an IP address to my laptop anymore. The laptop connects to the
ad hoc network, but hangs on 'acquiring IP address' or something like
that, and finally times out and gets a default IP address. If I run
ipconfig /renew in a command window on the laptop, I get the message
that the DHCP server cannot be reached.
Any ideas? Why would Win XP DHCP suddenly stop working after 2 weeks or
so?

Note: When ICS did work, I could run ipconfig /renew at will and
receive a new IP address from the ICS computer successfully, every
single time.

Note2: If I assign manual IP addresses to both the host and the client
computers, they can ping each other and I can transfer files etc
(proving that my ad hoc network actually works)
Thanks for any info! cheers!
