Therefore, in this article we will provide ways to eliminate this problem.
Restoring a wireless network connection
Wi-Fi can not work for many reasons, but all of them are divided into two large categories: hardware and software, and for each of them there is a method for eliminating failure. We can not consider everything to united, but here are the most common revealing and tell how to fix them.Method 1: Wi-Fi hardware
Since the laptop, first of all, a mobile device, manufacturers are achieved as long as possible from the battery. It so happened that the wireless networks, including Wi-Fi - the second in the list of "voraciousness", therefore, in most laptops, it is possible to manually turn off the wireless module from the supply by a separate key or combination with Fn, as well as the switch.

Method 3: Disconnection of the energy-saving mode
Often the laptop ceases to connect to Wi-Fay after exiting the sleeping state or during the action of the power saving mode. In this case, the problem in software is crashing, fix that can only be rebooting the laptop. From such a trouble, you can save the exception of the module deactivation in the settings of the device's power plan.

- Restart your laptop.
The problem will be solved, but the price of increased consumption of battery resources.
Method 4: Installing a network adapter drivers
The most popular reason for the irrevocability of Wai-fi on laptops running Windows 7 is installed inappropriate drivers for the corresponding module or software is not installed at all. Most often, users who have just reinstalled the system are often faced with such a problem. In this case, you need to download the appropriate software package and install it.

Method 7: Troubleshooting Trouble
The problem with the disability Wi-Fi can also be not in a laptop, but in the router that this very Wi-Fi is distributed. Typically, the failure is isolated, and the restart of the router can be corrected.

Conclusion
We have considered ways to solve the problem of unavailability of Wi-Fi on laptops with installed Windows 7. As we see, the reasons for such a problem can be a set, starting from a single software failure and ending with the incorrect firmware of the network router.
