Here's my issue: I have a 24" iMac (running 10.5.5) and an older AirPort Express (802.11 b/g only). When the AX is in the garage (I have a 1-story home) I do hear music and then it cuts out and my iMac shows a -3256 error message. When I move the AX into the house, I have no problems and the music streams just fine, no interruptions. I did buy another AirPort Express today. I put the new AX in the garage and the same problem. So would using both Expresses set-up as a WDS solve my issue? I was thinking that one AX can be used to extend the wireless range to the second AX. This is only to stream music and I do NOT need/want any Internet connection through this network - just music only. I tried setting up a WDS but the instructions I saw did not seem to match my OS version. I also tried the "extend wireless network" option. I noticed that this option only appears if I used the new AX to create my wireless network, Air Tunes. Thanks in advance for any help - either step by step instructions or pointing me in the right direction. I tried searching but did not find a solution that worked for me.
