wireless connection dropping after update install

Running Vista Business on a Dell latitude D620 2G Ram,

Before installing updates yesterday, my wireless connectivity has been
flawless. After yesterday's updates, my wireless connection drops about
every hour. A computer restart fixes the connection. These are yesterday's
updates:

2007 Office Suite SP1
Office 2003 SP3
Business Contact Man. for Outlook 2007 SP1 (KB941652)
NVIDIA Quadro NVS 110M

Thanks for your help.

Actually, my wireless was not dropping - just my internet connection. Only a
computer reboot would restore internet, but it would drop again within an
hour.

I finally fixed it today (I hope!) by updating my Bios from Dell - posted
after the MS updates, so I'm guessing I wasn't the only Dell customer having
problems with the lastest updates.
