XP Pro SP3 updated a lot. I just set up wireless networking between two laptops on my new Linksys WRT160Nv3 router. Everything seems fine. One of the laptops is always on my desk and was previously on the router via Ethernet cable. Shouldn't I be able to just switch the "desktop" enablment from wireless back to wired and still access the other one which remains on wireless? (I'm online now using the ethernet connection.) Perhaps I'm barking up the wrong tree. The older computer doesn't have hardware for modern security protocols like WPA. My idea was to bypass that by wiring it but have modern security on the one I move around the house.
