Broadcom 54g MaxPerformance 802.11g

[JOESOME]

Hi, I'm trying to connect to the net using my Broadcom 54g MaxPerformance 802.11g wireless card (Driver version 3.30.15.0) on my e-machines 6805. I've a Netgear wireless router and the wired connection works fine. Even the wireless connection status window shows that the connection is fine. But, when I do an ipconfig, it does not return any default gateway. I'd appreciate any help in this regard.
