How to write WiFi detail into the Hotspot:
Method 1: Generate WiFi config file, and plug it into TF card.
We need a TF reader.Put our TF card into this TF reader and plug this into our computer.
Go tohttp://www.pistar.uk/wifi_builder.phpand then fill your WIFI name into the SSID, password into the PSK, click submit. Then the file “wpa_supplicant.conf” is generated. Drag this file into your TF card’s boot path. And plug the card into your hotspot. Power up your hotspot, and wait for 1-2minutes.Then we go tohttp://pi-starand play with the settings. Please keep this in mind that gadget only support 2.4 Gigahertz router, and it does not work with 5.8G router.



Method 2: Use tmp WiFi to add new WiFi info into hotspot
For convenience, we have placed a tmp WiFi config file in the TF card.Tmp WiFiSSID ism100, password is abc12345. You can make up a tmp wifi by you mobie phone,using the same SSID and the same password. Connect your computer to this tmp wifi, and go tohttp://pi-star, login, use the username pi-star and password raspberry. The hotspot will auto connect to this tmp wifi so.



Add network and write you home wifi ssid and psk(make sure the ssid and password is right).
Then save and connect.
Close the tmp mobile hotspot. Restart the MMDVM hotspot, it will auto connect to your home wifi.
After about 2 minutes, you can go tohttp://pi-star, and check the current wifi name.
