How should I make a point-to-point wireless home system?
dryicerx: There is the Ethernet-over-Power option (they seem to work a lot lower than their rated speeds, but over longer distances / walls might be better in some cases compared to wireless). (Linksys PLK300, or D-Link DHP-301, etc).Before shelling out that much, I would try getting a second router to act in client mode and have high gain or directional antenna on both routers.
