I've searched several threads in this forum for an answer, but haven't seen anything definitive, so here goes... I currently have Verizon Fios and use their wireless router (Actiontec MI424WR) to provide my home's WiFi signal. The issue is that the installation is in the basement, and my office two floors above does not have the best WiFi signal. The house is wired for ethernet, so my question is... Will an Airport Express extend the WiFi network created by the Fios router if I connect the Airport Express to the Fios router via ethernet? If so, which port on the new model Airport Express would I use... LAN or WAN? Thanks for the time.
