My problem resolved! what i did was set the mode in router to only .11/g instead of mix, by doing this i still not able to resolve my problem. so i drop an email to dlink support and went to bed.
Thank you for Dlink support, next day, i got their reply with the following steps:
Step 1 Go to Apple menu> System Preferences> Network. The Network
window will pop up
Step 2 In the Location, click New Location. You will be prompted to
Name your new location. You can give it any name, e.g. WirelessLAN. Click
OK.
Step 3 In the Show pop-up list, select AirPort.
Step 4 Select PPP tab first. Make sure the PPP option is disabled.
Step 5 Select TCP/IP tab. In the Configure pop-up list, select Using
DHCP.
Step 6 Select AirPort tab. Click "Join a specific network".
Step 7 In the Network field, type the SSID of the wireless network,
e.g. "default".
Step 8 In the Password field, type the WEP Key if you are using
Encryption. To use encryption, you must use a HEX key.
To enter a HEX key on
the Apple product, enter a dollar sign ($) before the key.(interesting uh...) For example:
For 64-bit encryption, enter $1234567890.
Step 9 Select Remember network password.
Step 10 Near the bottom of the AirPort tab, de-select Allow this
computer to create networks (if you do not need Ad Hoc networks).
Step 11 Select Show Airport Status in menu bar.
Step 12 Click Apply Now.
Step 13 Save changes when prompted.
However, it still unable resolve my issue. Then i try again hooked up to the cable connection. Surprisingly i able access to the router and change it to WPA instead of WEP. and it works!!!
I just want to share this workaround with you guys, hope to help little bit for those who might have the similar problem with me.
MACBOOK really a beautiful masterpiece~
