I am using
Hostname    OpenWrt
Model    NETGEAR WNDR3700v4
Firmware Version    OpenWrt Chaos Calmer 15.05.1 / LuCI 15.05-149-g0d8bbd2 Release (git-15.363.78009-956be55)
Kernel Version    3.18.23

I replaced wpad-mini with wpad.

I connected to the network using luci. The following are the generated files

/etc/config/wireless

config wifi-iface
    option network 'wwan1'
    option ssid 'UR_Connected'
    option device 'radio1'
    option mode 'sta'
    option bssid '00:A6:CA:69:0E:EB'
    option encryption 'wpa2'
    option eap_type 'peap'
    option identity 'id'
    option password 'password'

/var/run/wpa_supplicant-wlan1.conf 

network={
    scan_ssid=1
    ssid="UR_Connected"
    key_mgmt=WPA-EAP
    identity="id"
    phase2="MSCHAPV2"
    password="password"
    eap=PEAP
    proto=RSN
    bssid=00:A6:CA:69:0E:EB
}

The following is the wpa_cli outputs
