what is the difference between wpa-psk tkip and wpa2-psk aes?
WPA-PSK (AES): This uses the original WPA protocol, but replaces TKIP with the more modern AES encryption. ... WPA2-PSK (TKIP): This uses the modern WPA2 standard with older TKIP encryption. This isn't secure, and is only a good idea if you have older devices that can't connect to a WPA2-PSK (AES) network.
