OK it was all configured and worked fine again - then Mac was rebooted and it doesn't see it now on the Airport Utility
I have moved the AEx so that it is actually in the same room as the wireless router and the Mac and that hasn't made it see it either.
The wireless signal strength from the router is very good, so I can't see that being the issue at all.
All I can assume is that I did something wrong on the configuration again - can anyone give me an idiots step by step guide to setting this up to purely play iTunes from the Mac to the speakers the AEx is plugged in to?
Thanks for moving the AEx into the wireless router room to try to eliminate that possible cause.
I guess after the reboot the AEx is flashing orange again?
It seems
*very* strange to me that it stopped working when the Mac was rebooted! I can't think of anything that could cause that, though something obviously is. The AEx isn't "connected" or "talking to" the Mac -- it's connected to your wireless router. Maybe something about rebooting the Mac causes your router to do something...
I'd bet you configured the AEx correctly (though I'll try to give instructions below). Instead, it's my guess that it's something about your wireless router or its configuration. You haven't said what brand/model you've got, so I'm guessing it's not an Apple device. Still, that
should be OK, but it might have behavior/configuration options I'm not familiar with.
What brand/model of wireless router are you using?
I've got an AEx set up the way you are trying to do it and the only issues I ever had were related to signal strength (I believe), so I'm sure it can be done. However I'm using a Time Capsule as my base router. My AEx is configured this way:
I'm using Airport Utility 6.3.1 (the latest) running on Mountain Lion (but should be the same for Mavericks, if that's what you're running).
Select the AEx and click Edit.
Base Station tab: give it a name and password if desired
Internet tab: Connect Using: DHCP. You shouldn't have to set anything else on this tab. I'm assuming your wireless router is acting as a DHCP server -- that's the typical situation. I think after you update the AEx, the IPv4 Address, Subnet Mask, and Router Address should all be filled in for you.
(
Or, are you trying to use static IP addresses?) You don't need anything on the Internet Options button.
Wireless tab: Network Mode: Join a wireless network; Wireless Network Name: pick your wireless router's network name; Security to match.
AirPlay tab: Enable AirPlay, of course. Give it a speaker name if desired. I don't use an AirPlay Speaker Password.
Click the Update button and that should do it. Pay close attention to see that it really stops working after the Mac reboot. Also, if it does stop working again, try simply unplugging and re-plugging the AEx power cord, if you haven't already tried that.
Very strange problem -- I hope we can get it working for you because AirPlay is fantastic, in my opinion!
-----------------
I've one last idea. Assuming you get it working and then it stops working again: Use Airport Utility to edit the AEx device, go to the
Internet tab and click the button labelled "Renew DHCP Lease". What I'm thinking is that the AEx is losing its IP address (which it normally gets from the router) and that by asking for new one it might start working again. (Not that that is a good solution, but such knowledge would help in troubleshooting.) This is just guess though -- I'm certainly not a networking expert!
Good Luck!
