wireless connection will not stay connected

[Peter V]

My wireless connection gets disconnected sporadically
(sometimes after 5 minutes, sometimes after 1 hour).

I am using a WRT54G Linksys wireless router and a
WindowsXP Professional (Dell Inspiron Laptop) with a
Microsoft MN-720 wireless notebook adapter for a 802.11g
connection.

Other than the sporadic disconnection issue, the setup
and regular operation is working fine.

I have tested and ruled out interference or distance from
the router (I am only 10ft away).

I have also tried the following:

1) Windows XP service pack 1a

2) turning off 802.1x authentication

3) disabling the Wireless Zero Configuration service as
per MSKnowledgebase article 821400. This broke the router
connection almost immediately due to a new
authenticiation error so I had to re-enable the service
to get the sporadically available wireless connection to
work again - therefore I am assuming this is not the
problem

4) Disabling ('never update') the Internet connection
status notification from the Broadband Network Utility in
the Windows taskbar

5) Checked for MN-720 driver update (none yet available)

Can someone please give me some more suggestions. I am
tempted to take the MN-720 back to the store and trade it
for another brand but based on the fact that my router,
internet sharing, security, and workgroup settings are
all working fine I am almost certain it is a WindowsXP or
Microsoft Broadband Utility setting somewhere that is not
configured properly. Please Help!!!

I'll answer my own question here in case someone else
runs into this problem. I turned off the power management
option which allows Windows to power off the wireless NIC
card. Things have been working fine (fingers crossed) for
the past few hours...

Microsoft Broadband Network Utility --> Tools --> Adapter
Settings --> Wireless adapter settings --> configure... --

General tab --> Connect using ...[wireless notebook

adapter name] Configure --> Power Management tab -->
UNCHECK 'Allow the computer to turn off this device to
save power'

Good Luck!

I believe I have fixed it by turning
