I need to extend the range of a Linksys WRT54G wireless router. A Linksys WRE54G (v2) wireless range expander was picked up, but isn't designed to work with Vista, and I'm not familiar enough with Vista to get it set up manually on a secured network. It worked fine with the network unsecured, but obviously you don't want to leave it that way. Both of the computers connecting to the network are Vista laptops, there are no other machines connecting to it.
They are in two seperate buildings, so something like the Netgear WGXB102 (something I glanced at in my googling) won't work. I was wondering if a high gain antenna would be the easiest solution, the other building is about 300~350 feet away from the router.
Thanks for any suggestions.
