Error problem with wireless adapter or access point

Hello Donat,

Thank you for posting your query in Microsoft Community. I appreciate your effort towards resolving the issue.

Did you make any significant hardware or software changes to the computer prior to this issue?

The issue may arise due to various reasons including incorrect TCP/IP settings configured, third party firewalls from anti-virus programs blocking the connection or due to incorrect advanced sharing settings. So, I would suggest you to try the following methods and check if you the system is able to detect the wireless network.

Method 1:

First of all, please verify if the WLAN service is started and set to automatic. If it is stopped, then I would suggest you to start the service and set it to Automatic.

1. Click on Start, type in services.msc in the Start search and hit ENTER.
2. Select WLAN Autoconfig service from the list, and double-click on it.
3. Change the startup type to Automatic and click Start to start the service.
4. Click Apply and then click OK.
5. Restart the computer and check if the network is detected. If not, proceed to Method 2.

Method 2:

Reset DNS and TCP/IP settings.

1. Click the Start button, click All programs, and click Accessories.
2. Right-click Command Prompt, and click Run as administrator. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
3. Please enter the following commands, and press enter after each one.

NETSH INT IP RESET

IPCONFIG /FLUSHDNS 4. Restart the computer to check the issue.

Check if the system is able to detect the network. If not, proceed to Method 3.

Method 3:

Assign a static Gateway as provided by your Service Provider.

1. Click on Start, type in ncpa.cpl in the Start search and hit ENTER.
2. Right-click the network connection (Local Area Connection) and click Properties.
3. Click to highlight "**Internet Protocol Version 4 (TCP/IPv4)**and click Properties.
4. Point Use the following IP address. According to your router’s settings, fill in the IP address, Subnet mask and Default gateway (as provided by your Service Provider).
5. Click OK.

If this method does not help, try the next method.

Method 4: Disable the security software temporarily and check if it helps.

**Disable antivirus software**

Note: Antivirus software can help protect your computer against viruses and other security threats. In most cases, you should not disable your antivirus software. If you do have to temporarily disable it to install other software, you should re-enable it as soon as you're done. If you are connected to the Internet or a network during the time your antivirus software is disabled, your computer is vulnerable to attacks.

Hello Harkanwar,

I tried all methods above including disabling firewall and all the security but, it doesn't seem to get fixed. are there any more methods or should i assume there's a hardware problem.

Thank you for your help,

Hi Shelly,

Thank you for the update.

You may want to restore the computer to previous point in time and check if it works as before.

Open System Restore by clicking the Start button . In the search box, type System Restore, and then, in the list of results, click System Restore.‌  If you're prompted for an administrator password or confirmation, type the password or provide confirmation.

Important: When you use System Restore to restore the computer to a previous state, programs and updates that you have installed after that date are removed.

Hope this helps.

I tried all but the last and nothing works.  This is exasperating!
