How can I extend my wireless network? I am having issues getting a good wireless connection in the basement where I spend most of my time, so I would like to extend the range of my network. I am currently using a linksys router upstairs, it is wired to the desktop in our home, so it cannot be moved down to the middle level of the house which would be ideal. I was hoping that an Airport Express would be a good option, but it sounds like my main router would have to be an Airport Extreme. I would rather have something like the airport express because when I move (live with my parents and should be moving out fairly soon) I would be able to use it as my main router because I will not need a wired connection. I do not want to spend $70-100 and only have an extender that I will not be able to use when I move. What are my options? I am going crazy with this crappy connection in the basement!
