hp CT100 (an hp computer tablet)

I have just obtained an hp CT1100 (computer tablet).  It includes a pen that isn't working and the ability to wirelessly acquire the network.  If anyone knows how the Network adapters acquire the networks, including satelite acquisition.  Please advise on how to get the pen working that's stored in the tablet computer and which network adapter to use, i.e. there are two adapters listed in Control Panel/Systems/Network adapters/(i.e.) Broadcom 440x 10/100 integrated controller, and, hp wlan 802.11a/b/g w500.  How would I configure one or both of those, and why does one have a red X through it, meaning it's disabled?  I ask because I seem to acquire the network in my car and lose it.  I assume it might have somethign to do with the Red X adapter.  Maybe?  Why is this happening?  What is it I need to know about the network adapters to be able to acquire a network connection even while travelling in a vehicle, but at least when I'm home and within range of my Linksys wireless router, a WRT54G v.5, how can I keep a connection?  My last request is, where can I find a complete users guide for this hp CT1100?
