Possibly this is a compatibility issue... go here: http://wi-fi-wireless-networking.suite101.com/article.cfm/wirelessrouter_alphabetsoup
802.11n -- The newest protocol, so new it hasn't been ratified. All that means is the IEEE hasn't yet voted and agreed on an official set of standards for 802.11n. This hasn't stopped the major manufacturers from selling 802.11n wireless routers though. Everyone from Linksys to D-Link has an 802.11n router on the market, and most computer equipment stores have drastically reduced the price of the 802.11g routers to introduce the 802.11n. Not all new computers come with an 802.11n card though, *so be careful when you decide which router to buy. Like 802.11g, 802.11n is backwards-compatible, with multiple options allowing almost any mix of old and new protocols.* However, performance problems remain an issue when mixing protocols within the network. 802.11n is expected to be ratified sometime in 2008.
Hi, Carolyn. Thanks for the pointer, but I am confident this is not a wireless compatibility issue. The only 802.11n devices on the network are my Mac Pro and the Airport Express. The AX is in N-only (5 GHz) mode, so nothing should be bothering it.
I can see both AX base stations in Airport Utility, and both sets of AirTunes speakers show up in iTunes.
If I start sending audio to the b/g AX, I can see in netstat that I have a connection to the AX and data is being sent:
steve@macpro:~$ netstat -n | grep 249
tcp4 0 131429 192.168.1.12.49259 192.168.1.249.6000 ESTABLISHED
tcp4 0 0 192.168.1.12.49258 192.168.1.249.5000 ESTABLISHED
(The third column is the send queue -- bytes sent by an application, but not yet transmitted on the wire.)
So, the data is being sent and I can ping the AX, yet no audio is played.
Ok... not a compatibility issue. AX just doesn't wanna play... at this point, try posting over in the Airport Forums. You will get more exposure to the pros beyond my experience. I don't want to suggest something that might add insult to injury. http://discussions.apple.com/category.jspa?categoryID=140
Also, MacWorld magazine (site) is also a great place for tips: http://www.macworld.com/
