Simple question! I am running a Dell Inspiron mini 10. No major problems if I don't have the best. I would like to extend my wifi range so I can go out on porch and still not lose connection with router. Right now I can set on porch and keep one bar most of the time. But it might drop out occasionally. I don't want to invest a lot of money. What criteria should I be looking for? Its a netgear router. I see there is several repeaters available at Walmart for $22 up to $99. I am thinking that the $22 dollar one will do me just fine. Would it be advisable to jump up a little bit to say mid range $50? Thanks
