Hi,
I am trying to use VoCore (RT5350 board) as wireless bridge with the following
wpa_supplicant config:
ctrl_interface=/var/run/wpa.sock
update_config=1
fast_reauth=1
ap_scan=1
network={
ssid="home_wifi"
psk=915644af001df2afbcf02df60f3fc27f9f7d7b09f1ac3667bb84e0776ec25e08
}
I do:
# iw dev wlan0 interface add client0 type station
# wpa_supplicant -i client0 -c ./wpa.conf -dd -t
And got log:
1436168056.380440: Successfully initialized wpa_supplicant
1436168057.769320: client0: SME: Trying to authenticate with 00:21:91:8b:61:c4

Looks like everything is fine:

But sometimes i got this without *ANY* logs or warnings on
kernel/wpa_supplicant,
And in this moment ping also fails:

OpenWrt version is r46180 with default config. (I just use
https://downloads.openwrt.org/snapshots/trunk/ramips/rt305x/openwrt-ramips-rt305x-vocore-squashfs-sysupgrade.bin
)
So, the question is: how i can debug this situation and get additional
logs/information about this issue ?
