Looking at the SNMP logs, I see the same error as you had 'received invalid class-3 frame', hence finding your site on Google. I have rotated these, and yes all three exhibit the same problem. Similar to another poster, I have 3 of these, where one is the main one, the other two are for speakers. I have been having the same problem as you describe, however it is almost 3 years after your original post.

Thanks for any advice (or sympathetic message -) It looks like they are all going back to the store unless I find a solution real quick (hint hint to Apple. I bought 3 of these AE devices to distribute around the house and none of them will stay connected (of course I am trying them individually before connecting them all.) I do not really want to use WDS on another channel as I got enough pain finding a clear one for my base, in a crowded neighborhood. Only AE power-cycling restores the connection, and that fix usually does not last more than 5 mn.Īnyone with the same issue? I was about to try setting DHCP client on the AE and reserve an address for it on the D-Link router, but after reading this discussion, that seems a move opposite to the solution :-( but the green light stays on, as if everything was well! Silly! The AE stays actively connected for a few minutes, then drops out (ping's to the AE static address fail the AE admin utility fails listing the device and rescans do not help iTunes does not see the AE anymore.). I am disconcerted to see this is actually the recommendation the Case 'closed' link above provides, since it does not work for me. My home networking policy already includes giving static IP addresses to any permanently connected network device, namely because DHCP service implementation too often reveals flaky on all routers I tried from different vendors (LinkSys, D-Link & Netgear devices) sometimes giving out the same address to different clients, sometimes denying service altogether!) I got the same problem with AE, firmware v6.3, set in client mode to a D-Link DI-624 router (latter does not support WDS, hence AE in client mode), WPA2 security, except it does persist with static IP address set up on the AE If it fails to do so, it will still display a green light. It looks like it does indeed disconnect from the network and then tries to reconnect. May 22 11:28:10 Severity: 5ĝisconnected from network.

This is the log file, shortly after the AAX has been running for 30 minutes. This is the setup: AAX, Firmware 6.1.1, operating in client mode in a WEP-encrypted network, network configuration by DCHP, AirTunes enabled. Rinse, repeat every dozen of hours or so.

My AAX drops off the network while still displaying a green LED that says: 'I am fine.' However, it isn't. It desperately needs a better way to communicate its current state. What's the deal? I think that the Apple Airport Express (AAX) is broken by design. It now has happened a number of times, so I am posting my issues now here at vowe's magic flying circus to give Google an opportunity to catch it.

What do you think Apple does with error reports in their forum? Admit that they have a problem? Forget it. Apple Airport Express dropping off the network by Volker Weber
