I need some advice. I am setting up a wireless network for a friend. There is a high speed connection at building A (some wireless internet will be needed here). There is another building (B) 600 feet away which will have multiple wireless clients for internet only (i think). I have two linksys v4 routers and two large omni antenna. I was thinking of running ddwrt v24 with building A as an access point and building B as repeater mode. Or.... should I be using wds? What is the difference?
