Accessing Wifi Captive Portal with Avenir Mini/Micro

Follow this procedure to access the splash page ("captive portal") through a local wifi device like an iPhone, in order to get internet access.

1. Remove LAN connection.
2. Remove any external modems.
3. Boot up Avenir Mini/Micro/Drone
4. Terminate WWAN connections in the Network settings. (Can be restored later.)
5. Connect iPhone (etc.) to Avenir Mini's access point.
6. In iPhone settings, go to network settings and set a custom DNS IP address: 8.8.8.8 (google's public DNS IP address)
7. Use iPhone browser to attempt to open any website. You should be re-directed to the captive portal screen.
8. Click buttons or enter info as needed to gain internet access.
9. Once browser is able to access internet, you can reconnect LAN, and reconnect WWAN modems (USB and internal), if desired.

You can do steps 5 and 6 ahead of time to save a little time, as long as the same iPhone (or other device) is used on the day-of. It's the phone's stored DNS setting that makes the difference.
