2. Reboot your PC/modem

Sometimes, a simple action such as restarting your PC or modem can work wonders. Keeping your devices plugged in for days on end may cause system resources to run low.

Reboot your PC, router, and modem and then try to enable the VPN connection again to see if this fixed the problem.

Also, make sure that your router supports VPN. You can go to the manufacturer’s website to check this information.  Don’t forget to log out of your VPN account and then sign back in.

3. Update your router

If you haven’t updated your router/ modem in a long time, this may explain why your system won’t support VPN connections.

Install the latest firmware updates available for your modem, restart the device and then try to connect to your VPN network again.

Updating your firmware is an advanced procedure. If you’re not careful you can cause permanent damage to your router, therefore use extra caution.

Install now TweakBit’s Driver Updater (approved by Microsoft and Norton) to automatically download all the outdated drivers on your PC.

4. Change the port/connection

Your VPN connection may not be available due to port issues. As a result, go to your VPN’s settings page and set the connection to another port.

5. Disable your antivirus/firewall

Sometimes, antivirus software or firewalls may prevent you from enabling your VPN. Temporarily disable these tools and turn on your VPN.

If this works, this means that your antivirus/ firewall is conflicting with your VPN connection.

In this case, add the VPN to your exceptions list and you’ll be able to use it with the antivirus/ firewall running on your PC.

  2. Go to Start > type services > double-click the first result.
