I will explain the issue the best I can. I live in rual Georgia. I have DSL at my house. My sister lives about 800 FT across a field. She can barely get a signal from my router maybe 1 bar if she is lucky. I have a WRT54G about 6 or 7 years old. She is not able to get DSL because her line going to her house is hooked to the old box down the road. I was thinking if I get a Wi-Fi antenna that goes outside whould that help? They are about $75.00 for antenna and wire. And if I put it on my end connected to my router it (the router) has 2 removeable antennas. Would I need 2? Maybe it would be bbetter to connect the antenna to her computer. BTW my router does have DD-WRT.
