My scenario, I have my router next to my cable modem in the first floor den, and i need it to reach all the way up stairs to the third floor, right now I get VERY low connectivity and the internet just wont work up there, now how can i boost the signal? I don't want to add wires nor do i want to spend hundreds and hundreds of dollars on equipment. I was thinking can I like put something on the second floor like a repeater or something like that to boost the signal up to the third floor? if so anyone got some links? I have a linksys WRT54G router. I was thinknig about getting the antennas that linksys made but I do not know if it'll increase it good enough. Looking to get something that is premade, i dont want to spend time building some cantenna or anything. And there is no computer on the 2nd floor nor do i have another to put there.
