Some laptops have wireless network usage problems after installing Windows 7 systems. For example, sometimes you can try to connect to a public wireless hotspot, but the best signal strength of a home without a line from the erection of the wireless network is not connected to the failure (see Figure 15), and even can not find a wireless hotspot. Some users may connect to the wireless network normally, but the blue screen phenomenon often occurs. There will also be a wireless switch function key that uses the notebook preset and cannot turn off the wireless network problem.
The workaround is to uninstall the official wireless card driver for the notebook manufacturer in the device Manager of the Win7 system. Then, in Device Manager, select Scan to detect hardware changes. The Win7 system is automatically installed with its own wireless network driver without manually loading the drive. Restart your computer and you will find that the problems mentioned above will be resolved or improved.
