I installed the Win7 32-bit Professional version, installed after the discovery of wireless network card is not found. Dell Ling n4030 himself with a wireless card. The source of the problem is that the wireless card driver is not installed or does not have a matching wireless card driver installed.
So the question is, what is the wireless card driver to match?
I looked for a long time on the official website, tried a few, can not. and also use the Dell official website to provide the system analysis, and then recommend the wireless card driver, still not. Finally, from the Internet to find a feeling of unreliable driver, after the installation incredibly OK. Now posted for reference only, hope to be helpful to everyone. The name is WLAN_BCM_5.60.48.18W7 driver.
