Solution 4: uninstalling/reinstalling mini ports
First, create a restore point:
To create a restore point on Windows 7:
- Open System by clicking the Start button, right-clicking Computer, and then clicking Properties.
- In the left pane, click System protection. If you’re prompted for an administrator password or confirmation, type the password or provide confirmation.
- Click the System Protection tab, and then click Create.
- In the System Protection dialog box, type a description, and then click Create.

To create a restore point on Windows 8:
a) Press Windows key + F, type “Create restore” in the search box
b) Click on the settings tile
c) From the System Protection tab, click on “Create?” and follow the process to create “Restore Point”
Next step: Uninstall the non-working miniports
When doing this, make a note of the miniports that you are removing, you’ll need to know this later when reinstalling.
Removing the Problematic WAN Miniport Driver
1. Press the start button then right-click My Computer > Properties. (Windows 8 users, right-click on the Bottom left side of the screen and select Device Manager)
2. From properties go to Device Manager; if you are using an older version of Windows you will need to click on the hardware tab to get to Device Manager.
3. On the Device Manager toolbar click on View and then click on Show hidden devices from the menu list.
So, to remove each non-working miniport, do the following:
1- Right-click on the non-working miniport, choose “Update Driver”.
2- Choose “Browse my computer”.
3- In the next window, choose “Let me pick driver from a list”.
4- Uncheck “Show compatible hardware”. From the “Manufacturer” list, choose “Microsoft”, and from the “Network Adapter” list, choose “MAC Bridge Miniport”. (It can be any device the user is allowed to uninstall.)
5- Back in the device manager, delete the device that just turned into the “MAC Bridge Miniport” device.
6- Once done removing the bad miniports, reboot.
Reinstall the miniports
You’ll need to do a few extra steps, as the miniport drivers aren’t meant to be installed by users and are not visible. To avoid editing .inf files (which in a lot of cases are protected and not easily editable), we’ll do it the long way.
Download devcon.exe and extract it on your C: drive root
Go to command prompt, go to the directory C:devconi386 for 32 bit and C:devconia64 for 64bit
For each miniport that you have previously uninstalled, execute the command outlined below. DO NOT run all of them or run the command twice, as that will create a second version of the existing miniport, which can cause problems again.
If running the command reports “driver install” failure, don’t pay much attention to it, it usually does. The only problem is when it complains about the inf file missing, or a missing class (in which case you most likely made a typo in the last part of the command).
Just copy the command and past it into the command prompt hit enter.
◦IKEv2:
devcon.exe install c:\Windows\inf\netavpna.inf MS_AgileVpnMiniport
◦IP:
devcon.exe install c:\Windows\inf\netrasa.inf MS_NdisWanIp
◦IPv6:
devcon.exe install c:\Windows\inf\netrasa.inf MS_NdisWanIpv6
◦Network Monitor:
devcon.exe install c:\Windows\inf\netrasa.inf MS_NdisWanBh
◦L2TP:
devcon.exe install c:\Windows\inf\netrasa.inf MS_L2tpMiniport
◦PPPoE:
devcon.exe install c:\Windows\inf\netrasa.inf MS_PppoeMiniport
◦PPTP:
devcon.exe install c:\Windows\inf\netrasa.inf MS_PptpMiniport
◦SSTP:
devcon.exe install c:\Windows\inf\netsstpa.inf MS_SstpMiniport
Once done, reboot. Again
This should resolve your issue.

You might get this error also if you are already connected to Dedicated IP with your other device. So check that before going all the hasle..
I’m on Windows 10 and the only solution was simply run PureVPN as administrator. No more 720 error.
devcon.exe is no longer available as an individual file. You need to download 800MB of Windows Driver Package. Better to reset your network by going in Settings > Network & Internet > Status > Network Reset —–>> works only for Windows 10.
We are sorry for the inconvenience. If you have followed above steps correctly and still getting error 720 then it may means that your mini ports are corrupted and you will need to reinstall Windows.
Let us know if you have further questions!
I will check if this guide does the trick!

I have tried to reset and remove the miniports without success.
My computer is a Surface Pro 4 – Windows 10.0.14965.
Only OpenVPN works
Uninstall pureVPN, reset network (and shutdown, don’t restart), and reinstall pureVPN.
(Reset network: Settings > Network & Internet > Status > Network Reset)
