iOS has a built in VPN client so PIA wants you to use that.

The guide is for an iPhone, but it is the same procedure for any other iOS device. The instructions are pretty straight forward so you shouldn't have difficulty following them.
As far as the router is concerned ...
Unfortunately each router is different and the default firmware is pretty locked up on most of them, unless you rock a enterprise device. If your device supports it you can install dd-wrt which I know for sure supports vpn tunneling, or maybe tomato. It's up to you.
If not you could get a RasPi, beaglebone or just an old computer and set it up as a gateway and use that for VPN tunneling. But that's a bit more advanced.
