My card doesn't support WPA2. So, I guess xwlan isn't going to help in this instance right?
Wrong. XWLAN is the program that connects WiFi to the hot spot, whether it is an open hot spot (no security), or using one of the, so called, secure connections (WEM, WPA, or WPA2). The security level, that you need, depends on how the hot spot (your router) is configured, and capable of. The suggestion that WPA2 may not work is valid (WPA may not work either), and that can happen even if the device does support WPA or WPA2. You probably don't want to actually use the device, if it won't connect at one of those two levels. This "security" has nothing, at all, to do with buying things on the internet. It is to prevent people from logging into your router, and using it (possibly to send SPAM, or PORN, to the world). Even WEP is so easy to bypass, that any high school kid can o it in about a minute.
We need to know, exactly, what the hardware is, to make intelligent suggestions. See my previous post. Please tell us what driver you are trying to use. Without all of that information, we can only guess at what you are trying to do, and there are a lot of possibilities.
Also, seriously consider getting, and using, an external WiFi adapter (that plugs into the wired LAN connector) for security reasons, as well as connection speed, unless you are doing this just for laughs. They are not very expensive, and will work a whole lot better than some antique PCMCIA card ever could. If you are doing this for laughs, READ every word in the documentation, at least three times, then ask questions about what you don't understand. There is no easy way to figure this out, and the solution may be completely different, for different hardware, and driver, combinations. It is also very likely that your hardware simply has no driver.
