Help! Windows cannot detect the networking hardware.

[XQMR]

I have a Windows 7 Home Premium 64 bit laptop. The processor is Pentium (R) Dual-Core CPU [email protected] with 4GB RAM. Since a forced abortion occurred when the system was doing its regular updates about a week ago, the laptop cannot be connected with the internet anymore. The message given by the Diagnosis is "Windows cannot detect the networking hardware". Other than the internet connection problem, the computer works as normal. Do I need to install a network driver? and where can I get the suitable driver? Any quick response on this topic would be appreciated!!!

(at bottom of the page, there's "related tutorials" to help you either)

you can use it also to uninstall the device and reboot to see if windows reinstall it.

Thanks for the advice. I reinstalled the network drivers and was able to regain the internet connection. However, yellow triangular marks with exclamation are still showing on a number of items under Network Adapter. A snapshot of the screen is attached here. Can you let me know if this indicates any problem? How to fix them? Thanks again!

What's about right click on each and try update the pilotes?

If it doesn't make anything, You can try a CHDSK
