AirPort Express (2012) drops network connection after ~1 hour...ideas?
I have a brand new 2012 AirPort Express (AX) that I'm using as a wireless Ethernet bridge -- it's configured to "extend a wireless network." I have wireless clients turned off so only Ethernet devices can connect to the AX. Anyway, it works fine for about an hour then it drops the wireless network connection with my main AEBS and its front panel light blinks amber. The only way to get it to reconnect to the network is to unplug it and plug it back in. I've already tried resetting the AX to factory defaults but that didn't resolve the issue.
I have another 1st gen AX and an AEBS that both are rock-solid when running as wireless bridges.
Any ideas? I'm thinking I either have a bad AX or it needs a yet-unreleased firmware update.
