Would Like To Setup Pia on a Linksys Wrt 1900 acs Router
I'm new here so for give me if this has been ask before but I would like to setup Pia on a Linksys Wrt 1900 Acs router the videos on pia website are outdated and do not match my router interface so its difficult for me to follow as being an older person. And by doing this open vpn would all my devices be protected in my home such as , Roku, mobile phone, laptops and so on? Furthermore, would I need to make some form of adjustment when streaming videos from my crackle, Filmon, Tubi or Channel Pear? Thank you for your patients....

Here is also a link to a article from our support center that talkes about firmware and also links to our installer guides. https://helpdesk.privateinternetaccess.com/hc/en-us/articles/219457267-Can-I-use-the-Private-Internet-Access-service-with-my-router-.
Also to answer your question, yes installing our client on your router will protect all devices running behind it. As for your second question if you are streaming videos with a torrent client, No special settings are required in your torrent software to run torrents on the VPN. We recommend that you use our port forwarding feature, though this feature is only available on our desktop applications: https://helpdesk.privateinternetaccess.com/hc/en-us/articles/219460187-How-do-I-enable-port-forwarding-on-my-VPN-.

@dew7157 Have you flashed DD-WRT at all on your router, or are you still on Linksys' interface? DD-WRT haven't changed their interface in years, so that leads me to think you're still on Linksys' original firmware. I don't know about this one specifically, but very few routers actually supports being OpenVPN clients by default.
If you can share a screenshot of the interface you see it could be pretty helpful for us to guide you through it.
"Out of the box, this router comes open source ready, so you can easily flash it with custom DD-WRT builds that are specially designed to make the most of its features. Or you buy one pre-flashed from FlashRouters. This is great, as it ensures you do not lose any of the router’s functionality when upgrading from the stock firmware to DD-WRT."
If you paid around >179USD or so you probably just have the basic router. The router that is flashed with OpenVPN Client is around ~350USD. The information is sketchy at best and sounds more like marketing talk.
It has two revisions and both are supported, so as long as you make sure to install the right one it should be fine!
Once you have flashed DD-WRT your interface will look exactly as on the guides. (And your router will have more features than you know what to do with.)

Understand that I am assuming you have not flashed a router before. Not intended to speak down to you at all.
edited for misspelling.
Start here: http://www.dd-wrt.com/wiki/index.php/Installation
You will not understand what they are talking about but the more you read and follow the links the more you will get the big picture. You can also look at youtube videos for flashing routers. The more you read, the more you watch, the more you will understand.
If you have a friend who is knowledgeable then ask them for help. If you just bought the router maybe you can return it and purchase one from the DD-WRT site or if PIA has preinstalled routers, but here. I will leave that up to you. But you want a router that has the ability to work as a VPN Client, not a server.
It's also got the most comprehensive OpenVPN configuration I've ever seen in a GUI. They literally put every single option as individual fields and checkboxes, that's really nice (*cough* hardcoded options in DD-WRT *cough*)
I think we should get back on topic tho to not confuse OP too much
I think the stock firmware is thankfully smart enough to not flash something that's not bootable/doesn't make sense to flash. Be careful with what you flash, it could have gone bad if you tried to flash the error page's code

Based on the information on this page
http://www.dd-wrt.com/wiki/index.php/Supported_Devices#Linksys_.28Wireless_a.2Fb.2Fg.2Fn.2Fac.29
the firmware for your router is located here
ftp://ftp.dd-wrt.com/betas/2015/08-20-2015-r27700/linksys-wrt1900ac/
If you click on the FTP link and it does not work, try removing the second ftp in the link.
Now for a disclaimer. I cannot nor will not guarantee if these files will work. This is why I said YOU need to do the research. One more thing, it is not the IMG file that gets loaded, it is the BIN file.
