I just ran three lengths of CAT5e under my house to the three rooms. Each length is about 60 to 70 feet. I connected the lines to my wireless router (Netgear WGR614) and tested the lines with my lap top in each room. I get no connection in any of the rooms. Do i need a booster of some sort? Where do i find out what the longest lengths of wire I can run before I have problems?
