If wpa2psk is out of the question entirely due to device and or network restrictions, use wpapsk with aes tkip.
Wep can be cracked in less than a minute with a packet sniffer, so its basically useless and im surprised the switch even supports it. My router currently offers wepwhich i know is garbage wpa wpa2 with encryption tkip and aes. Airhead community explains this is because group ciphers will always drop to the lowest cipher.

Wpa uses either a 64bit or 128bit key, the most common being 64bit for home routers. Wpa2 wireless security cracked the researchers have now shown that a brute force attack on the wpa2 password is possible and that it can be exploited, although the time taken to break into a system rises with longer and longer passwords. Wpa tkip cracked in a minute time to move on to wpa2. If possible, it is recommended to remove tkip support, although these.
Then using a direct ethernet connection i change the modem wireless security settings to wpa2 psk with aes, as this setting is available in the drop down list.
