Setup Wifi using WPA on Axioo CMPC

At last, I can connect to AP using WPA after reading /usr/src/rt73-k2wrlz-1.1.0/IWPRIV_USAGE. On line 191, documentation is very clear:

d> Config STA to link with AP which is WPAPSK/TKIP(Authentication/Encryption)
        1. iwpriv wlan0 set NetworkType=Infra
        2. iwpriv wlan0 set AuthMode=WPAPSK
        3. iwpriv wlan0 set EncrypType=TKIP
        4. iwpriv wlan0 set SSID="AP's SSID"
        5. iwpriv wlan0 set WPAPSK="12345678"
        6. iwpriv wlan0 set SSID="AP's SSID"

    p.s Step 4 is part of generating wpapsk password and is necessary.

Now my remaining problem is to put those iwprivs into appropriate file in /etc/sysconfig/network-scripts/
