I notice that I have had a lot of connection issues with XP's SP1 machine's adapters and wireless routers and APs. Everything in these machines is updated except the Service Pack. By contrast, I have never had problems with SP2, either using Windows own wireless connection utility or the app that comes with the adapter. Is this true for you people as well? Also the same applies to Windows 2000 Professional even with the latest updates including SP4 with the latest (and last) Rollup.
