This has taken me ages of searching this forum and others to set up my 2 airport express base stations. Main reason is to boost the wifi around my property Plugged one into the socket near my wireless router and put the Ethernet cable not this. Plugged my other one into a socket not to far away. Open up airport utility's This will bring up both expresses Manual set up Change settings Wireless name changed Up the multicast rate to 11 Mbps Creat closed network User interference robustness Done Wds add secondary express Type in its ip address Wait for both to restart All inkeep getting is the settings for this airport device have been successfully updated but there as a problem rejoining the wireless network or finding the airport device. You may need to select your network from the wifi menu or try again. I have tried this numerous times resetting even swapping them around but nothing at all. They are only 2ft apart and nothing I between. Please help.
