In general terms...some geared towards a WM2003 OS device, but suitable for your use...

Starting on  'Page 8-11 ' in the rx3000  'User's Guide' or starting on 'Page 15' of the 'How Do
I...?' guide, both of which you should have on the companion CD that came with your device or you
can download from HP, see the steps required to access a WiFi network...

After reading...

* Make sure your Connection Manager is set for "Work". This page is for the WM 2003 OS, but should
be close enough for your device for you to figure out (if you read your User's Guide)...

* Match the WEP/WPA key on both the wireless access point/router and the PocketPC. Note you may
need to use a Hex representation of the WEP key on the PocketPC...

* Make sure the wireless network SSID on the PocketPC matches the Linksys SSID. If the SSID is being
broadcast that should be picked up automatically by the PocketPC.

* See if you get a valid IP on the PocketPC. Use vxIPConfig or vxUtil for that. The IP should be in
the 192.168.X.X range and not in the 169.X.X.X range.

* If you get a valid IP see if you can ping desktops by IP address. Use vxUtil for that.

* See this page for help with ActiveSync over an 802.11b link...

You first have to sync it with the wired USB connection, then you can sync
