Hi I have a couple of airport expresses that are extending the range of the wifi network thats provided by an airport extreme - everything works fine. I have a macpro in the garage thats a server for the network and is wired on the network. I can use this mac to use create a 'new' wireless network using its airport card but what i'd really like is to 'extend' the current network so that devices dont need to switch networks and just roam to a new access point. Back story to this is that i'm trying to get better wifi coverage in the garden and the garage is in a perfect spot for this, and it works fine, but only on a different SSID. Any thoughts if this is possible or would i need to buy yet another airport express? I had thought of just using the same SSID with the same password but this could cause other issues i am sure. any thoughts?
