Correction "Windows cannot connect to the selected network"

I use Windows 7 on my desktop machine and ran into an annoying problem the other day. I tried to connect to my wireless network at home like I normally do, but I can't connect. I kept getting the following error message:

 Windows non  in grado di connettersi alla rete selezionata 

Strange problem! I also had this error once before when I installed Windows 7 on a new computer and refused to connect to any wireless network. I tried to remember everything I did to fix it the last time and it worked again. List all the methods you can try to solve the wireless connectivity problem.

Release / Renew IP address

You can first try to release and renew the IP address in case it is simply a problem with the IP address. You can do it in two ways. You can try to simply restart the computer or you can run some commands from the command prompt. Or you can try both.

To run the commands, click Start, then type CMD in the search box. Press Enter and you will get the command prompt dialog. Now simply type in these two commands:

 ipconfig / release ipconfig / renew 

You should see something similar to the one I have above in the screenshot, but instead of saying Ethernet adapter, I say wireless network adapter. If an error occurs while trying to release or renew the DHCP server, there may be a problem with the wireless router, which is the second thing to try.

Restart the wireless router

The second thing to try restart the wireless router, if possible access it. If you are trying to connect to someone else's wireless router or to an hotspot at an airport, for example, obviously you will not be able to do it and the problem may remain with your computer. You can skip this part and continue reading if this is your scenario.

Otherwise, go ahead and turn off the router completely, then wait about 30 seconds and turn it back on. Wireless routers are known to have all kinds of strange connection problems and most of the time the problem can be solved by simply restarting.

Disable security on the wireless router

Depending on the type of wireless card you have and the security settings for the wireless router, it may simply be impossible to connect because the security encryption on the router is too advanced and your network card does not support it.

To test this, try temporarily disabling or disabling security on your wireless router to see if you can connect. You will need to log in to the router and go to the wireless settings page and choose None or Disable.

If you can connect, basically a problem with security settings. You may need to update the drivers on the network adapter or you may need to upgrade to the operating system to the latest service pack. For example, make sure you are using Windows XP SP3 to connect to the latest wireless routers.

Update the network card drivers

Also, if there is a security problem between the two devices, you need to update the drivers for the network card. The latest drivers can support higher encryption on the wireless router and thus allow connection.

Even if you bought a computer recently, it's always a good idea to go directly to the website of the network card manufacturer and download the driver from there. You can see the exact model of your network card by going to Start, Control Panel, System and clicking on Device Manager in the left menu.

Expand Network cards and you will get a list of all the network adapters on your computer. It should have the company and the model number in the list itself. Make sure you install the correct version based on the operating system you are running.

Enable Network Discovery

There are occasions when certain settings are changed on your computer and you have no idea how. One of these could be Network Discovery, which allows Windows to talk and connect to other computers and network devices. To make sure it's turned on, go to the Control Panel and click on Network and Sharing Center. In the left pane, click Change advanced sharing settings .

Now make sure the radio button is selected Enable network detection .

If turned off for any reason, this could have caused the problem where you could not connect to a wireless network or even a problem where the wireless network could not be displayed in the list.

Use network troubleshooting

Windows has a small troubleshooting tool in Windows 7 that can eventually solve your problem. It's called Network Troubleshooter and you can access it by right-clicking on the wireless icon in the taskbar and choosing Troubleshooting .

A dialog box will appear and I will try to detect any network problems.

If this does not solve your problem, read on and we hope to find a solution soon!

Windows XP and shared encryption

If this problem occurs on Windows XP, there may be a problem where the wireless router has shared encryption open rather than open encryption. You can work around this by manually adding the wireless network to your computer. To do this, go to Control Panel and then Network Connections. Right-click on the wireless network card and select properties .

Then click on the tab Wireless networks and click on the button add .

Finally, go ahead and type in the SSID for the wireless router and set Network authentication to shared . By default set to Open as in the image below, so you have to change it to Shared. Also, uncheck the box that says " This key is provided automatically ".

Manually enter the network key and click OK. If this was the problem, you will now be connected to the wireless network. a little annoying, but it works. So nothing else is working for you and you're not sure what kind of encryption the router is using and you're on Windows XP, give it a try.

USB wireless adapters

If you use a wireless dongle or one of those wireless adapters connected to a computer via USB, the problem is probably related to the device itself. These wireless USB adapters tend to have problems since connected via USB.

Here are a couple of things you can try for these types of adapters:

1. Turn off your computer completely and disconnect it! S, disconnect it! Then turn it back on and see if you can connect.

2. Try using a different USB port for the wireless adapter.

3. Uninstall all USB devices from Device Manager and then allow the computer to reinstall them

4. Update the drivers for the USB adapter

Uninstall the security software

As a last resort, your problem may be related to some kind of security software. This is especially true for business computers that have Symantec Endpoint Protection or some other crazy security software. If you can, try uninstalling it and see if the problem is solved.

Other programs to try and uninstall include Microsoft Security Essentials and any type of Norton software. If you find the problem occurred, try another product or try reinstalling it.

These are pretty much all the possible solutions I've found on this particular wireless problem. If something else worked for you, post a comment here and let us know! If the problems persist, tell us the configuration and we will try to help you. To enjoy!
