PC Challenged,
I see a valid IP address for the DW1525 (802.11n) WLAN PCIe Card
I would try shutting down the computer, unplug it from the wall, then press and hold the power button for 30 seconds. Try reseating the DW1525 (802.11n) WLAN PCIe Card and make sure the antenna is connected.
How far away is this computer from your wireless router?
What do you see in your device manager?
What virus program and firewall are you using?
