Did you ever get your problem worked out with Linksys? We have Linksys also and my wife's laptop has Vista but we have had no problems at all. If you found out something that could potentially be a problem, I would like to hear about it. Thanks.
On top of 40hrs @ work, I'm taking exams this week and next, so my time is limited. But I do have a 4hr open block next week that I hope to get in touch w/ them. If y'all are up and running, the problem is probably on my end, but if I run into anything I'll let you know.
