Whenever I enable WiFi password on my network, all the Mac's in the house drop to 802.11a, instead of N.

Here are the screenshots of a password-less world.

Now as soon as that password is enabled (WPA2-PSK [AES]) - all connections automatically drop to 802.11a, and so does the transmit speed.

I would understand if this was the case with TKIP or both TKIP&AES being enabled, but I only go for the AES.

Why is this the case? Can you recommend a solution which would prevent 'a' from ever being connected to, and only 'n' be the functional network.

Thank you.
