Why is wireless module zd1211rw loading ?
Aug 16 12:13:42 (none) user.warn kernel: zd1211rw: Unknown symbol ieee80211_beacon_get
What wireless device is registered as wlan0 ?
Edit /etc/network.conf if wlan0 change wlan0 -> wlan1

Please post lspci and lsusb output if you need further assistance.

Thanks for reply

I have 2 wifi cards: TP-WN422G v1, which uses zd1211rw module and TP-WN422G v2 which i try to lunch. TP-WN422G v1 was recognized as wlan0 and worked perfectly. The problem is i have to setup slitaz to work with TP-WN422G v2 on 20 computers (20 TP-WN422G v2 cards are already bought, so i cannot use the older, working one :( )

I dont have installed usbutils, so lsusb dont work now, i will try to install it and post result if it can help.

You should be able to connect with TP-WN422G v2 by editing /etc/network.conf as I described above and not removing either adapter or unplugging the TP-WN422G v1, which uses zd1211rw module and reboot.This would make TP-WN422G v2 become wlan0 since it is now the only wireless adapter. Add ath9k_htc to LOAD_MODULES= of /etc/rcS.conf to autoload on boot if necessary.

I have changed network.conf to wlan1. I have tried to use also network.conf from TL-WN422G v1 card, with wlan0 and wlan1. But when i do /etc/init.d/network.sh restart - i have:

wlan1 is not a wifi interface, changing it.
Configuring ...ifconfig: up: error fetching interface information: Device not found


And no internet connection :/

SOLVED :):):)

I have deleted "#confirm if $WIFI_INTERFACE is the wifi interface" section form /etc/init.d network.sh and after restart it works!

Thanks for support

which os do you have on the tplink - ddwrt?

it reminds me to a thread (I am sorry german, but google could translate) with the ath9k driver - the result was, that wpa_supplicant must be >= 6.9

there are also this starnge errors
