I am on a Linksys wireless router at home. The router is downstairs and on the left side of the house while my computer (Dell Inspiron 600m with Intel wirelessLAN 2100 3A Mini PCI adapter) is upstairs and on the right side of the house. Needless to say, I'm having signal problems and bought the range-extender antenna from radioshack and am having minimal success with that. I've heard of the signal booster that linksys makes that you put on the top of the router. Is that my best bet? An access point maybe?
