This solution applies to Wi-Fi enabled bttns with older firmware (manufactured and shipped between December 2014 and February 2015).

The default wireless encryption used by bttn is WPA/WPA2.

To connect your bttn to an open network, do the following.

1. Start the bttn's Wi-Fi access point (by holding it pressed when inserting power, until blue LEDs turn on)

2. Use your phone or PC to join the Wi-Fi network named "bttnconf"

3. Use browser to go to address (notice: no /bttn at the end!)

4. You should see a form titled "SPWF01 First Config"

5. Fill in the form as follows:

- Insert miniAP PassKey: anonymous

- Insert the SSID: your network SSID, currently spaces or special characters may not work

- Insert the PSK: [leave this blank]

- Insert Static IP Address: [leave this blank]

- Insert Static NetMask: [leave this blank]

- Insert Static GW Address: [leave this blank]

- Insert Static DNS Address: [leave this blank]

- Turn on/off DNS/DHCP: ON

- Choose Auth Type: Open System

- Choose Auth: Open

- Choose Mode: Station

Click "GO!" and then "Ok" when an alert box shows.

6. Then wait a few seconds until red LED ring appears on your bttn.

7. Power cycle bttn (remove and re-insert batteries or micro-USB power adapter).

Your bttn should now connect to your Wi-Fi network. You can also check from your router settings, if you see a new device in your network.
