I should mention my case is for static WEP key with IEEE8021X key
management. Does wpa_supplicant allow this?

--- my_wpa.conf ---

network = {
	ssid="myssid"
	scan_ssid=1
	key_mgmt=IEEE8021X
	identity="id"
	password="password"
	ca_cert="/home/..."
	group=WEP40
	wep_key0=<key>
	wep_tx_keyidx=0
	eap=PEAP
	phase2="auth=MD5"
}

Thanks,
