I’ve had a couple of people mention to me that they have problems with their wireless connectivity in Windows XP, but I assumed it was just a fluke. Well, apparently not. Lots of other people have experienced the same problem, but of course Microsoft denies all fault. Anyway, the second page of that article mentions a work-around that seems to generally restore wireless when it isn’t working. From the looks of it, restarting the computer would also work, but would take lots longer.
