Ok,
Yes I would use my AR300M to run your Netflix VPN. I’m assuming you aren’t running two Netflix streams at the same time.
I’d have my notebook/desktop/tablet/smartphone connected to my main router SSID (non-VPN) and load the appropriate Windscribe client on my device for browsing the web, and you can easily turn it off for complete non-VPN service on your device. In fact to be honest, the device based VPN client/extension is normally faster than going through a router based VPN and with a couple of clicks you could use a VPN endpoint from anywhere in the world! :).
Windscribe includes clients/browser extension for:
Mac, Windows, Chrome, Firefox, iPhone,Linux
If your television is wired to your AR300M then you’d only have 1 SSID (you can turn off your AR300M LAN WiFi) but at most if your television is WiFi connected to your AR300m you’d only have to have 2 SSIDS .
Using this method I suspect you’ll get better performance all round and better flexibility to change your VPN end point on your devices for browsing.
The only “issue” would be having to go to your AR300M web interface to change VPN from Germany/US (though I’m not sure but you might be able to write a script to change the switch on the AR300M to toggle between US and Germany) and having to turn on/off your VPN extension on your mobile device 
This is pretty much how I run my system at home. Same principle but I run PureVPN on Mango and only use US VPN and run PureVPN device apps/extensions on my endpoints
