Actually, the 6300 had the longest range from the tests I saw. And I think 200ft would be pushing it, even with the best of the best. Hope there's not much in the way to hinder the signal.
Since XP is old and dead you may need the drivers off this site, but if you use 7, you likely won't. As my thread and others posts may have hinted, Intel's drivers are problematic, but the ones 7 installs work fine.
To set the router up you'll likely need to use the lan jack for the initial setup/firmware updates.
Thank you for your quick response. I know that I am pushing the range, but I have no choice; since there are no barriers (trees, and such) to hinder the signal I hope my chances are better. If this does not work I have one other option. The Ayrstone Ayrmesh wi-Fi system (www.ayrstone.com) for $350 is a possible solution. I do have a couple more questions though. Are you refering to Intel's 6300 Wireless adapter as opposed to the 6230? If that is the case Dell only has the 6230 as an option. As for the OS I will be using Windows 7, so I will use the default Windows drivers as you stated. As far as the router setup you're saying I should hard connect the laptop to the router for initial wireless setup and then disconnect, am I correct in that understanding?
