On Apple's website under information about Airport Express it mentions that the express can automatically detect an existing airport signal and extend the range of the first wireless router. Apple says that this function will work with Airport systems only. My question is, can I get the express to extend the range of a wifi signal that isn't coming out of an airport base station? I am going to need better range at an event im working at but the wireless router there is a linksys I believe. Please advise the best option is there is one.
