WLAN manager help

Need some help about configuring connection with WEP encryption.
This is the default config file for WEP:
# WEP
ctrl_interface=/var/run/wpa_supplicant.socket
ap_scan=2

network={
ssid="My ESSID"
scan_ssid=1
mode=0
key_mgmt=NONE
auth_alg=OPEN
wep_key0="....."
wep_tx_keyidx=0
}

I change only the "ssid"(name of my WLAN network) and "wep_key0"(my WEP key). Should i change anything else, becouse this way is not working? If i switch off the encryption, and put the settings for free network, the WLAN adapter connects and is working just fine with my IPbox9000HD. Anyway i want to use my WEP encryption, so if someone can help will be greatly appreciated!
Thanks for the nice plugin!

Thanks for the help mate, but using auth_alg=SHARED it cannot connect at all. I'm using linksys wifi router and 64bits 10 hex digits WEP encryption. For example if my key is 1234567890, how to put it into config file? Directly, or converted somehow? In all other connected devices i put the key directly and is working.
I forgot to mention that using the setting from the firs post, i get msg that the WLAN is connected, but actually i don't have access to my box via ftp, and no internet. I can scan other available networks, and see that i'am connected to my local WLAN.
Maybe this key_mgmt=NONE should be changed also?
Thanks in advance!

PS. I've just tested with WPA and everything now is working fine!
