Trouble with hostap and reseting card

[Pavel Bareš]

Hi


I have a trouble with hostap driver

I have 3 Z-Com XI 626 in AP mode on Mandrake 10  kernel  2.6.3-9mdkcustom

When I have hight trafic (1.5 Mbs) on wlan0 and wlan1 simultaneously or
high trafic on any interface from 2 or more clients driver report :

Jun 15 11:11:21 localhost kernel: NETDEV WATCHDOG: wifi0: transmit timed out
Jun 15 11:11:21 localhost kernel: wifi0: CMD=010b EVSTAT=0000
OFFSET0=0000 OFFSET1=0000 SWSUPPORT0=8a32
Jun 15 11:11:21 localhost kernel: wifi0: scheduled card reset
Jun 15 11:11:21 localhost kernel: wifi0: Original COR value: 0x32
Jun 15 11:11:21 localhost kernel: wifi0: Setting ALC to 0
Jun 15 11:11:21 localhost kernel: wifi0: Setting TX power to 160

This mesage repat and stop trafic on wlan0
I must ifconfig wlan0 down and ifconfig wlan0 up
Somtetimes router hung after this error.

I think that this problem connect with overload of interface. It
is evoke hight trafic or many errors during transfer.

I try:
fw 1.8.0 and 1.7.4
hostap 0.1.3, 0.2.1, CSV
other PC
but this troubel still repeated.

Other router with similar configuratinon works fine.

Could you explain me what does it mean and what is the reason of this
problem.

Please help me.

Sorry for my bad English.
