Alright, let's see. I have a (GB ethernet) AEBS running in N (5GHz) only mode, connected via Ethernet to a APEx which runs in B/G mode and connects to my sound system via Airtunes. I've had just a storage drive as an Airdisk connected to the AEBS for a while and it worked well enough. Not super fast, maybe 5 minutes to write a gig to it, and having to mount it at start up was a little annoying, but it worked. Now that TM works over Airdisk I decided to try and work things out to work for me. Attached a little (powered) USB 2.0 hub, connected both hard drives. Worked well enough, until further use showed TM backs up very slow, the storage drive writes really slow, and accesses slowly, and quite often when TM machine is going, Airtunes will drop out (sometimes resuming later). All my music IS on the shared Airdisk. But on top of that even before the TM stuff, Airtunes has been dropping. Nothing else had changed and it had never had issues, but now songs/albums will pause arbitrarily, sometimes resuming, sometimes not. Anyone have any tips? Is the hub to blame? Will a "better" one make the situation better? Is my set up flawed to begin with? I just wanna have TM going, my storage/music connected with non-abysmal transfer/read speeds, and Airtunes to work properly.
