This configuration is for associating and authenticating with access point
using the WPA or WPA-2 (Wifi Protected Access) encryption standard[1] using
PSK (Pre Shared Key). Client side authentication management is via
wpa_supplicant.
If you used this config to connect to a WEP encrypted access point, you would
periodically associate, but fail to authenticate soon after. This process
would cycle indefinitely.

This configuration is for associating and authenticating with an access point
using the WEP (Wired Equivalent Privacy) encryption standard[2]. Client side
authentication settings are managed via iwconfig from wireless-tools.

Since you seem to be comparing apples to oranges, there is clearly no tests to
be done to fix the problem you describe above, as the only problem I can see
is misinformation.
Do you have a reason for using wpa_supplicant for a static configuration
defined in /etc/network/interfaces when the stanza using wireless-tools magic
hooks Just Works?
If you did, a wpa_supplicant.conf block for connecting to a WEP access point
would look like:
network={
ssid="MyWiFi"
key_mgmt=NONE
wep_key0=ABACADAEAF
wep_tx_keyidx=0
}
Translated to be used from /etc/network/interfaces:
iface wlan0 inet dhcp
wpa-ssid MyWiFi
wpa-key-mgmt NONE
wpa-wep-key0 ABACADAEAF
wpa-wep-tx-keyidx 0
And although the above is a theroetically supported configuration (via the
wpasupplicant/ifupdown scripts) I still question why you would prefer this
method for a statically defined network when wireless-tools is all that is
required.
Thanks, Kel.
