If you can place the Wireless router in a visible spot like a window that you can SEE the antennas from the house 150 to 200 feet away, it may just work find if you limit the speed to 1 megabit or a lower number that what B or G WiFi gives you.

There's no need for me to write what hardware or connections since that would just duplicate what's at the http://www.linksys.com site.
