Wifi Doesn’t Work On Windows 7

Hello dear friends. As you probably already understood from the title, today I decided to touch upon a very serious and painful topic, and try to figure out what to do when Wi-Fi does not work on my laptop or netbook and how to connect the laptop to a Wi-Fi router. By the way, it can be not only a laptop, or a netbook, it can also be a regular desktop computer with a Wi-Fi receiver. There have been a lot of similar issues lately, mainly to the article Wi-Fi network without access to the Internet. We solve the problem using the TP-Link router as an example.

Wifi Doesnt Work On Windows 7

Now we’ll try to figure out step by step what and why problems may appear when connecting the laptop to a wireless Wi-Fi network. We’ll also try to find a solution to this very popular and unpleasant problem with connecting to Wi-Fi, or rather a failed connection.

Most often, problems arise when the Wi-Fi module on the laptop cannot be turned on. And when Wi-Fi turns on, the laptop finds all available networks, but when trying to connect it writes “Windows could not connect to.”. We need to check whether the drivers are installed on the Wi-Fi adapter, whether Wi-Fi is turned on on the laptop, etc. Now we will do this.

I noticed that most often problems with connecting to Wi-Fi are found in Windows 7. It is on this OS that a network error without access to the Internet very often appears, I wrote how to solve this problem in the article, the link to which is above. In fact, as practice shows, there can be many causes of this problem. And if there are many reasons, then there are many ways in which you can make a laptop connect to a Wi-Fi router.

But the laptop, the netbook, etc. are not always to blame. There may be a problem in the access point, that is, in a Wi-Fi router. And the first thing we need to do when there is a problem connecting to Wi-Fi is to determine the reason, in a laptop, or in a Wi-Fi router. Now I will consider the problem of connecting to my own router. Because, if you are unable to establish a connection with someone else’s Wi-Fi, then all claims to the neighbor, this is most likely his problem :).

Who is to blame, a laptop, or a Wi-Fi router?

As I wrote above, you first need to find the culprit. Before you make any settings on a laptop or Wi-Fi router, you need to understand what the problem is, because of which it is not possible to connect the laptop to Wi-Fi. It’s just possible to set it up so that then you have to do a factory reset and set it all up again. The best way to determine which device is hiding the problem is to try connecting another device, such as another laptop, tablet, or phone, to the router. A laptop that has problems connecting to Wi-Fi, you need to try connecting to another wireless network.

I think you understand my point. If other devices (best of all with the same operating system) connect to your router without problems, then the problem is in the laptop. Read this article further, now let’s try to solve it.

Well, if problems with connecting to your network arise on other devices, and a “problematic” laptop connects to other networks without problems, then the problem is in setting up a Wi-Fi router. See the article on setting up a Wi-Fi router TP-Link TL-WR841N, it may come in handy.

Check if the driver is installed on Wi-Fi

I will use an example of a laptop that runs on Windows 7. This is by far the most popular operating system.

I advise you to immediately pay attention to the icon that displays the status of the Internet connection. It is located in the notification panel.

If your internet connection status looks like this:

First you need to check if the drivers are installed on Wi-Fi and if the Wi-Fi adapter is turned on.

Right-click on “My Computer” and select “Properties”. On the left, select “Device Manager”.

In the new window, open the “Network Adapters” tab and see if there is a device like Wireless network adapter (you may have it called differently). If you have such a device, then right-click on it and select “Properties”. Another window will open, make sure that it says “The device is operating normally.”

If everything is about the same as mine above in the screenshot, then everything is fine, the driver is installed. And if there is no Wireless Network Adapter device and you have unidentified devices, go to the website of your laptop manufacturer, download and install the driver on the Wireless Network Adapter for your model.

We dealt with the drivers.

Check if Wi-Fi is enabled on the laptop

If the driver is installed, but the Wi-Fi module is disabled, then the connection status will be the same:

Usually the wireless adapter on the laptop is turned on, but it won’t hurt to check. Wi-Fi on laptops (netbooks) is usually turned on and off by a combination of keys. On my ASUS K56cm, these are the keys Fn f2. But although when I press these keys, I get a message that the wireless adapters are on / off, but nothing happens. Look for a key on your laptop Fn and key with the image of a wireless network. Press them at the same time.

On some laptops, there may be a special switch on the case that you can enable or disable Wi-Fi. For example on Toshiba Satellite L300 it looks like this:

Turn on or turn off the Wi-Fi wireless adapter in Windows 7

But the best way to check if the wireless adapter is working or not is to go to the network control center and see.

So on the notification panel, right-click on the Internet connection status icon and select “Network and Sharing Center”.

Then select “Change adapter settings” on the left.

Among the connections we are looking for “Wireless Network Connection”. If everything is fine and the Wi-Fi adapter is turned on, then it should look like this:

If the adapter is disabled, it will look like the screenshot below. Right-click on it and select “Enable”.

In the ways described above, we must make sure that the status of the Internet connection in the notification panel is like this:

This status means “No connection. There are connections available”. This means that the Wi-Fi adapter is turned on and there are available wireless networks for connection.

If the connection status is like this:

This means that Wi-Fi is turned on, but just the laptop does not see the networks available for connection.

The error “Windows could not connect to.”

With a problem, when the wireless network module is disabled, or does not work at all, we figured it out. Now, consider the case when the laptop finds available Wi-Fi networks, but when trying to connect to Wi-Fi it writes: “Windows could not connect to.”, where instead of dots the name of the network you want to connect to.

If you have a network connection status such as in the screenshot above (through one, a network with a yellow icon), then click on it and you will see a list of networks available for connection.

Select the desired network, click on it, then click on the “Connect” button.

If the set is password protected, then Windows will ask you to enter a password. Enter the password for the network and click “OK”.

And if everything is fine, then your laptop should connect to the Internet wirelessly. And the status of your Internet connection should look like this:

But at the very moment of connection, very often the error “Windows could not connect to.” appears. It looks like this:

Unfortunately, friends, there is no definite solution to this problem. But I can download that very often the problem with such an error appears due to the settings of the Wi-Fi router. Maybe it’s through the type of security and encryption that is installed on the Wi-Fi router, read more about this in the article How to set (change) the password for the Wi-Fi network on the TP-Link TL-WR841N router. There may also be a problem with the distribution of IP addresses.

If you notice, then in the window with the error “Windows could not connect to.” there is an opportunity to run “Troubleshooting”, sin not to take advantage. Try to run, somewhere I heard that there are cases in which it helps :). But seriously, sometimes it really helps. Windows will check the availability of the wireless adapter, check the settings, etc. And if it can, it will fix the problem that prevents you from connecting to Wi-Fi.

I also advise you to disable the item “Allow disabling this device to save power”. Sometimes this helps to eliminate and avoid many problems with connecting to the Internet. Read more about how to do this in the article Wi-Fi Internet connection disappears after exiting sleep mode.


I noticed that in Windows this error appears when the settings that are saved on the computer for your network do not match the current network settings. I’ll explain now.

For example, your laptop was connected to Wi-Fi, it automatically connected to the network. But you took and changed the password, or the type of network encryption. Now the laptop is trying to connect to the network, but the parameters no longer match, and that’s the error.

Enough, just remove the network on the computer and establish a connection again. I wrote about this in the article How to remove a wireless network connection and reconnect to Wi-Fi?


A great article has turned out, and I hope that it is useful. She wrote it for half a day, of course, with interruptions, there were still problems with adding screenshots to the site, but I sort of decided.

I tried to collect all the necessary information that should help you solve the problem that occurs when connecting a laptop or netbook to Wi-Fi. If I forgot to write something, then in the future I will definitely supplement the article, I will also be very grateful if you share information in the comments that helped you solve the problem with connecting to a wireless network.

If you have any questions, then ask them in the comments, we will try to figure it out. Good luck!
