Have you got servicepack 1 installed?

Mine seems to have it installed as my internet explorer version is 3.0.1
pocket word, excel, powerpoint and access 3.0.1
Also Download the Handheld PC Pro 128-bit SSL Update

make sure you have no other connections set up
look in start > Programs > Communication > Remote Networking
Also try compatible drivers for your card
from other manufacturers..
I believe the Linksys WPC11 uses an Intersil Prism2 chipset
Here is a good list of wireless network cards and their chipsets

If the Linksys drivers do not allow you to access the net then try
a driver for another card with the same chipset as yours..
