device_id_0x4727 So for a PCI device with Vendor ID 14E4 and Device ID 4727 (CC_0280 I am not sure, anyone?), we can determine it is a "Dell Wireless 1501/1503/1701 Half Mini Card Driver", with Broadcom chipset.

As for Dell Wireless 1501/1503 and 1701 card driver, we need to go to Dell website to find and download the driver. I have found the Windows XP driver for it. Besides the Windows XP driver dated back to 2011 I could not find a newer driver from Dell website.

I tried download the driver from Dell website and extracted it. Then I found out that there are two folders with names like /Dell_Vista and /Dell_Win7, with files name "bcmwl6.inf". So this means you can use the driver for Windows 7 as well.

Extra information from the driver file:
