  1. AnyConnect provides reliable and easy-to-deploy encrypted network connectivity from devices by delivering persistent corporate access for users on the go. Whether providing access to business email, a virtual desktop session, or most other Android applications, AnyConnect enables business-critical application connectivity.
  2. My Cisco Anyconnect VPN Client keeps on disconnecting after I changed my laptop and upgraded to windows 10. My internet connection is same and it was working fine on my previous laptop. In Device Manager under Network Adapter I see a warning sign on my Microsoft Wi-Fi Direct Virtual Adapter.

AnyConnect clients do not have internet access. AnyConnect clients cannot communicate between each other. AnyConnect clients cannot establish phone calls. AnyConnect clients can establish phone calls.

I use Cisco AnyConnect on my Windows 7 computer to make VPN connections. It also has capability to connect to WiFi. But I always had problems in connecting toWiFi with AnyConnect. Connection drops frequently and it keeps saying ‘Acquiring IP address‘.

AnyConnect installs a service called ‘Network Access Manager‘ which seems like takes over the native Windows WiFi connecting client. So when I click on the network icon in the System tray it says ‘No connections are available'(See below snapshot). Without AnyConnect, it always displays the WiFi connections available.

If you are facing the problem then you can try the following solution that worked for me.

  • Open Services management console by running Services.msc from Run
  • Find the service ‘Cisco AnyConnect Network Access Manager‘.
  • Right click and stop the service.
  • Now Cisco AnyConnect will say ‘NAM service unavailable
  • Now Windows will use the native WiFi client to connect to the WiFi
  • When you reboot your system, the NAM service will start and may cause problem again. You can disable this service in Services management console to prevent that.

AnyConnect has settings to disable the NAM feature. But that did not work for me. Even after disabling NAM service, I could not connect to WiFi. Windows network icon shows the WiFi connection but gives the error ‘Windows was not able to connect to…‘. I followed the below steps to do this.

  • Opened Anyconnect window and click on Advanced.
  • Clicked on ‘Networks’ tab in the left side pane.
  • Clicked on Configuration tab. Changed the NAM to disabled as shown below.

The following is a contribution to the knowledge base of my current employer.

A user states that her laptop is quickly switching between available wireless networks, but cannot establish an actual connection.

Cause and Prevention:

This issue frequently occurs when users select wireless networks with the basic Windows connection tool instead of Cisco Anyconnect. Advise users that they should ALWAYS use Cisco Anyconnect to select wireless networks.

Resolution:

Ensure that the user entered the proper wireless security key, and that other devices (iPads or personal computers) can connect to the network. If the network is valid, do the following:

  • In the system tray, right click on the flag icon (“Solve PC issues”) and select “Troubleshoot a problem.”
  • Click “Network and Internet.”
  • Click “Network Adapter” and select next on the prompt that follows.
  • Select “Wireless Network Connection” and click next. Windows should begin automatic troubleshooting.
  • Click close to end troubleshooting and verify that Cisco Anyconnect can connect to a network.

If the issue is not resolved after this, schedule a session with a remote tech to have NIC drivers reinstalled.
