Because you put "authentication key-management wpa" under the SSID, and "encryption mode ciphers tkip" under the interface, the AP will use WPA, not WPA2. Change the encryption mode to aes-ccm, and that will change your connection to WPA2. 802.11n only supports open and WPA2 authentication - NOT WPA.
Also, on a 2.4GHz radio, the "channel width 40-above" is not needed. That radio doesn't support 40MHz channels - that requires a 5GHz radio, which the 1141 doesn't have. Also, I would normally hard code the channel (1, 6, or 11 - depending on your regulatory requirements).
