I think PP01L is your battery or battery charger. emoticon.Wink.title Most likely you have a Lattitude laptop.
If it doesn't already have ethernet, just about any PCMCIA or USB ethernet adapter should fit the bill, but "the best" is subjective. With wireless, I always try to get the adapter that matches the manufacturer of my wireless access point, but for ethernet, one is as good as another. And, without knowing what you're connecting it to, you might as well spend the few extra bucks to get a gigabit (1000MB) model.
What i meant to say is the Ethernet card for the dell latitude model pp01l =).
Again that is not a valid Dell model number. If you go to http://support.dell.com, try to find it there. I can't find it.
It is a Dell model number - it's the model code for a Latitude C610. It already has a built-in network adapter.
That makes more sense. I have never heard people referring to a PP01L.
