Description

I run two TP-link 841N with BARRIER BREAKER (14.07, r42625)

With one of my wifi clients (a sony ericsson, xperia, cyanogenmod) I get very frequent disconnects to any type of wifi access point I create on openwrt (WPA, WPA2, plain, ...)

openwrt log:

On the cyanogemod side I could see in the wpa log for one dis-/reconnect:

All other devices work pretty well on my openwrts. And the android does work well on other APs.
I assume I have some troubles in firmware/software of the openwrt, but failed to identify any.

I also tried to set nohwcrypt = 1 with no success.

wifi config looks like:

config wifi-device 'radio0'
	option type 'mac80211'
	option hwmode '11g'
	option path 'platform/ar934x_wmac'
	option country 'DE'
	option txpower '20'
	option channel '2'

To tackle the problem of beeing 'inactive' I tried to run a continious 'ping $GATEWAY' which tentatively ends in a more stable connection, but still disconnections happen. And that is really not a workaround.

Any hints?
