Description

AP interface(s?) stops working after a short while (5-10 minutes). Clients gets kicked and can't reconnect. This has been verified on more than one platform (all we tried with this version).

Platform:

  • Gateworks Cambria (ixp4xx)
  • 3x Compex WLM54AG radio cards (two in adhoc mode and one in AP mode).

Software:

  • Linux 2.6.27.6
  • Hostapd 0.6.9

Dmesg tells me (over and over):

Also, not sure if it's related, but this sporadically shows up in dmesg:

 wifi2: ath_fatal_tasklet: Hardware error; resetting.

Wifi2 being the AP interface.
