DR Danise - Do you have a tech guy at work you could consult with? Or maybe just walk in tomorrow with your Pocket PC and WiFi card, and dangle them in front of his/her face/desk... "Oh, do you need help getting that set up?" *And if you're office also has a wireless network set-up, you should be able to access that.
OOHHH!!!!!
I think that may be the root of your problem... Did you get a standard WiFi modem card? Or did you get a Wireless Network Card for your Pocket PC?
When I was looking at a wireless card for my Pocket PC, I was looking for a wireless network card. Yes, it's basically WiFi, but the protocols are different. With a wireless network card, you can access a wireless network - WiFi, Linksys, Airport, etc. And you don't need an ISP to do so. Once you set it up on your Pocket PC, once you open IE, it should find the nearest access point.
*That's why I was sort of surprised you needed an ISP to access a WiFi access point. Yes, Wifi is a wireless network, but there are other ways to access a wireless network. When I travel with my laptop and a hotel offers wireless, high-speed access, I just have to tell my wireless card to recognize the signal in my room/lobby/etc.
**Of course, this also assumes that the wireless network you are accessing has Broadband capability. Some wireless networks are office set-ups, just to communicate from computer to computer. But most wireless "networks" setup in hotels have internet access capability - at least in my experience and travels.
Have you tried going into a Starbucks? Most locations offer wireless internet access. Barnes & Noble's have also started setting up "hot spots" in their stores.
And then there's the whole Bluetooth "solution" too, but that's another totally different - yet similar - story.
However...
I also noticed that while browsing the HP site that there are some models of iPaqs that simply don't work with wireless cards - WiFi or otherwise. It's just a matter of the actual hardware in the iPaq model.
A couple of years ago, I had bought Steve a wireless card for his laptop - an HP, actually. I installed the drivers, I updated the connection settings, but when I placed the card into the PCMCIA slot, nothing happened. I tried this, I tried that. After a few days, and many frustrating hours - Heck, the thing worked on my laptop! - we finally consulted the HP site. We looked up his model number, and started reading through the spec sheet. OH!!! -And then after calling HP, our worst "fear" was confirmed: His particular laptop model was not built to handle wireless cards even though the software was "accepted". Whatever processor, dip-switch, etc., that was needed to properly configure a wireless connection was not a part of his laptop's configuration.
If you'd like, feel free to e-mail me your specifics - model of your iPaq, which WiFi card you bought, which version of Windows Pocket PC you are running, etc. I'll see what I can do on my end.
*And, finally, if Internet Explorer was not already present on your iPaq, that may be the tip-off that your iPaq does not have remote internet/wireless capability.
