#20584: ctrl-event-disconnected reason=4
---------------------------------------+-----------------------------------
Reporter: bastian-openwrttrac2015@… | Owner: developers
Type: defect | Status: new
Priority: normal | Milestone:
Component: kernel | Version: Barrier Breaker 14.07
Keywords: wifi disconnect |
---------------------------------------+-----------------------------------
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?
