Look in the example wpa_supplicant.conf for network blocks that use WEP
(key_mgmt=NONE, wep_key0=xxxxx, wep_tx_keyidx=0).  For WPA stuff, you
have a lot of options, where the D-Link router has simplified them.
Rough conversions are:

WPA
----------
key_mgmt=WPA-PSK
proto=WPA
pairwise=TKIP
group=TKIP

WPA2
----------
key_mgmt=WPA-PSK
proto=RSN
pairwise=CCMP
group=CCMP

WPA-Auto
----------
key_mgmt=WPA-PSK
proto=RSN WPA
pairwise=TKIP CCMP
group=TKIP CCMP
