I'm having internet issues after updating the VPN!

If, after updating your VPN, you've started to have internet issues where it doesn't connect to any network, it keeps booting you off the internet, or your VPN client will not connect, check these items:

Solution 1: Check for Multiple Cisco Secure Client Applications

Open up Control Panel:

Click Uninstall a program

Look for Cisco Secure Client - AnyConnect VPN

This is the only "Cisco Secure Client" app that you should have installed.

If you have more installed, as shown here:

Then uninstall all of those extra apps except for AnyConnect VPN.

After you've uninstalled them, you'll need to restart your laptop.

You should then be good to go and no longer have those internet connectivity issues.

Solution 2: Check the Cisco VPN Network Adapter and DNS Settings

If you're still experiencing connectivity issues after removing extra Cisco applications, or your VPN client will not connect, the problem might be related to the VPN network adapter and its DNS settings:

1. Open Network Adapter settings (Windows):

   • Right-click the network icon in the taskbar and select Open Network & Internet settings.

   • Click Change adapter options (or Advanced network settings > More network adapter options).

2. Locate the Cisco/VPN adapter:

   • Look for a network adapter named something like Cisco Secure Client, Cisco AnyConnect, or similar.

   • If the adapter is disabled, right-click it and choose Enable.

3. Configure the Cisco/VPN adapter to use DHCP for IP and DNS:

   • Right-click the Cisco/VPN adapter and select Properties.

   • Select Internet Protocol Version 4 (TCP/IPv4) and click Properties.

   • Make sure both of these are selected:

     • Obtain an IP address automatically

     • Obtain DNS server address automatically

   • Click OK to apply the settings.

4. Optional: Temporarily test with Google DNS on Wi‑Fi:

   • For troubleshooting only, you can hardcode your Wi‑Fi adapter DNS to Google DNS: 8.8.8.8 (and optionally 8.8.4.4).

   • If this allows the VPN to connect, it suggests a DNS-related issue. After testing, it's recommended to switch the Wi‑Fi adapter back to Obtain DNS server address automatically for a more stable, long-term configuration.

Solution 3: Troubleshooting Slow VPN Connections or Timeout Errors

If you're experiencing slow VPN activity or navigation timeout errors, try these steps:

1. Restart your device to resolve temporary connection issues

2. Verify your internet connection stability

3. Ensure you're using the latest VPN client version

4. If problems persist on a specific server, try:

   • Saving your current work and logging out

   • Transferring to an alternative server to improve connection performance

Additional Troubleshooting Steps

If the above solutions don't resolve your issue, try these additional steps:

1. Restart your computer

2. Run the following commands in Command Prompt (as administrator):

   • ipconfig /release

   • ipconfig /renew

   • ipconfig /flushdns

3. Disable and re-enable your WiFi adapter

4. Verify your WiFi driver is up to date

5. Run Windows Updates
