I'm moving my future musings about my Wireless stability issues here to keep from cluttering other threads. I'm not looking for any quick resolution feedback, but I want to keep posting findings as I dig deeper in case anyone else has similar problems. If anyone happens to have an idea, please let me know.
The log below was captured today with the HM4+rPi running with the Edimax wireless chip.
In this setup, I have both lan and wlan enabled, but there is no ethernet cable connected.
So, for some reason, USB is disconnecting. I captured a nearly identical event shortly after this without the HM board connected (rPi only) and with lan disabled (ifdown eth0). usb is reset a number of times using dwc_otg, but continues to disconnect after 30-40 seconds. This is consistent with the LAN failures and resets that I saw when only using eth0.
Unplugging the Edimax usb rebooted the rPi board.
