If your Betterspot doesn't assign a valid IP address to your device, the device cannot get connected to Betterspot. To solve this issue, you need to assign your device a static IP address as below:
IP address: 192.168.151.X (X can be any number between 2 to 255 -But remember! The number must be different for each device that you want to connect to Betterspot).
Subnet mask: 24 (255.255.255.0)
Default gateway (router): 192.168.151.1
DNS server: 192.168.151.1
The following pictures show how to set a static IP address in different operating systems:
