bbmadzkyHi! In the span of three months after this post reply, does Dell already have a solution for this problem? I sometimes encounter my WLAN Card 1397 for Inspiron 1545. On some occasions, clicking the network icon in Windows 8's notification bar does nothing even the said device is present in the Device Manager. I presume it has driver problems that leaves users unable to connect to wireless networks. Please do reply asap on this matter. It's really giving me headaches.
Try installation of the Dell Wireless 1501 driver:

It should update the driver however installation failed in my 1390 card gave an "Update.cpc 828" error.
