Dear Vishal, thank you for your prompt response. I really appreciate it. I tried solution A in your post, but it didn't do the trick. So, I tried the drivers mentioned in the following article instead, which solved the problem. www.forlanda.net/.../re-installing-windows-7-on-a-dell-inspiron-m5040 The network adapters were detected by the laptop and I can connect to the internet now.

Recently I re-installed Windows 7 on my friend's DELL Inspiron M5040 laptop. However, now it cannot connect to the wireless network. I checked the Device Manager in the Control Panel and I see that both the Ethernet and Network Controllers are currently not recognized by the system.  I downloaded the following driver from DELL's website -- [URL] -- however, it doesn't seem to work either. I would appreciate it very much if someone could let me know how I could download the drivers so that I can connect to the WiFi network. Looking forward to getting some helpful pointers from the DELL community. Best regards,y0ht0nka
