The range of my wireless network was not very good so people suggested to me that I should go for a range expander. My wireless is a G-wireless connection and I looked at Linksys wre54g for that. Has anyone used these kind of products? How do these things work? Tell me how do we install these expanders. Since I am considering to get one for myself please let me know with which operating systems does the Linksys wre54g work? Would it work only with the G wireless?
