Hi I have 2x soekris 4501 units with atheros adapters, 1=hostap mode, 1=client. With a continues ping, everything keeps running (16+ hours), but after an inactive period they lose connectivity. The client still reports it is associated, but there is no IP connectivity. After "ath down" + "ath up" it does not want to associated with hostap any more. After client reboot it works fine again. After inactive period - same problem.
