Hi, I just started using private internet acces. I was able to get everything going quite easily, except for my Asus router. But I finally got it working, so I thought I share and hopefully spare some of you some time and frustration.

I have a Asus rt-ac66u router with stock firmware version 3.0.0.4.380_4005

The solution to getting OpenVPN to work had to do with the order of inputting the different settings.

Go to VPN in the left pane, then click the VPN Client tab, click Add profile and click the OpenVPN tab.

It is very important to enter the username and password AT THE VERY END!!!

Step 1. UPLOAD the .ovpn file
Step 2. UPLOAD the ca file
Step 3. Type in username, password and VPN description.
Step 3. Press OK

and Activate! :-)

For extra speed, replace the following in the .ovpn file.
change 
comp-lzo
to
comp-lzo no push "comp-lzo no" 

Good luck

    I've got the AC68u and it's working although without it activated I'm getting 8.22mbps and with it activated 2.86mbps melbourne or 1.71mbps Sydney.
    Is this right? 
    I've opened the .ovpn file in notepad but couildn't see "comp-lzo" to change it.
    Any help would be appreciated...

    OK, the problem for me was, I'd been trying to update the firmware on the router but it kept saying it still needed updating as it wasn't rebooting after installing new firmware, once I did a reboot it's now fine obtaining very close to without vpn speeds.

    I started out not being able to get the VPN Client working in the stock firmware using just the above settings.

    I was able to get this working as well, but with a few modifications in other settings in the router prior to it being successful.

    Once I set up the router with the following settings, under Advanced Settings, then WAN, then in the Internet Connection tab, it worked like a charm:

    1. WAN Connection type: Select "Automatic IP"

    2. Enable WAN, NAT and UPnP options

    3. Connect to DNS Server automatically: Check "No"

    4. DNS Server1: 208.67.222.222

    5. DNS Server2: 8.8.8.8

    6. DHCP query frequency: Select "Aggressive Mode"

    Then I continued to the VPN section, under VPN Client, where I created a profile and continued using the steps above from KALENDS.

    These are steps I found from:

    Where I was able to take their instructions, and modify/apply them using PIA steps and the required files.  Now it works.
