>Description:
ifconfig ath0 powersave
ifconfig: SIOCS80211POWER: Invalid argument
ifconfig: exec_matches: Invalid argument

Without powersave on the access point, mobile devices do not work.
SIP phones will not ring if called.
On a Nokia S60 phone you can disable power save but that will eat up your 
battery charge in less than a day.

I think this is related to #34621

maybe also to this:
