I can only setup WEP ecryption even though my router and wireless NIC supports WPA, I tried PSK string and Hex Im using a D-Link router G604-T I think its my NIC because ive had problem with it because it shut down my pc when i ran areuras yesterday, its a Excel wirless and im pretty sure its a dogy brand. Im kicking myself becasue the net gear was about $5 more. There is no manufactures website I can find, I rand belarc and the only info I could get was it was made by marvel and it is IEEE 802.11g Wireless Cardbus/PCI Adapter I went to the website and it was a seriosly crap website and i couldn't even find the card. Is there someone how has had the same problem perhaps with ths same card. Im thinking of returning it but i need a good excuse or they wont accept it.
