AT+WA Time to connect to AP

Question

Dear All, i have connectect WIZFI220 to a MCU and it works perfect. However, I have a problem with the time the WIZFI chip needed to connect to the AP. After issuing the command AT+WA=testAP; I have to wait at least 20 seconds. How can I reduce the 20 seeconds waiting connection to less than 10 seconds? Is the problem related to the Firmware of the WIZFI? Any suggestions, it would be a great assist to me. Thank you for your support.

Is there any problem in the firmware of the WIZFI. Is there any documentation about the timing of the chip. Im using SPI to communicate with the chip. So I reset the CHIP and then I wait around 1 second then sends an AT Command to initialize the chip. The next commands that I used AT+WD, ATC1, AT+ NDHCP=1, AT+WWPA=. Then I connect AT+ WA=TEST The Problem is that the the timing of powering the chip until the connection is more than 15 seconds and I need to know if it is possible to reduce it less than 10. I believe the problem is in the Firmware of the WIZFI. Any suggestions would be helpful.
