Fedora Networking :: D-Link DWA-125 Wireless 150 USB Adapter?

I have "D-Link DWA-125 Wireless 150 USB Adapter". I can use this wireless adapter on my laptop, i can use it on my desktop as well but only when windows is running, im a newbie to fedora, today is my 2nd day and 3rd night, so pretty exited about it. i have installed fedora 13 on a different hard-disk on my desktop. when the computer is booting, there is an orange light on the adapter glowing, it turns off when the computer reaches the fedora loading screen. If i see fedora's Network Configuration window under the hardware's tab i see the "D-Link DWA-125 Wireless 150 USB Adapter" listed along with my lan card. Now if i go towards the clock on the top right to get the wireless connection working, it shows wireless network disconnected. I have tried creating wireless connection manually by inserting the SSID, macadress, BSSID, ,WPA passkey etc, but still doesnt works. when i try connecting using hidden wireless connection, i receive window for inserting keyring password again and again, stating that the login password does not match. but during all this time, i still havent seen the orange light glowing activity on the external usb adapter. If i restart the computer in windows the adapter/wireless connection works. also have checked the Network service, it seems that the service is up and running. i really require some assisstance on this,

i have noticed this, that if i go under network configuration. the first tab over there, inside devices i cant see my D-Link adapter, but if i switch onto the hardware tab it shows my lan card as well as my D-Link adapter. so does it means that the driver is missing? or any service which is disabled, however at this point of time i can get only using wired connection. please assist me. with this issue, im also downloading the 500 complete update as well for fedora, hoping that it may make it work.
