Configuring your Windows XP system to use LetNet Wireless

Here we'll take a look at how to configure Windows XP-based computers to use LetNet Wireless.  It's worth noting, however, that there are still a couple of potential roadblocks or gotchas that could make this information irrelevant.  The first one is that your computer must have a wireless adapter that supports connections via the PEAP security method.  Most any vaguely-recently-manufactured one will, but there are some in existence that do not.  Second, while Windows XP has a built-in wireless connection manager tool - the one we're showing how to configure in this article - many computers come with a third-party wireless configuration tool that looks completely different.  In most cases, you can just disable that third-party tool and just use the Windows wireless system as shown here.  However, there are a lot of different manufacturers with a lot of different kinds of proprietary wireless software - so it is possible that your mileage may vary.
