Hi, I assume you mean you lost internet connectivity when you connect to Solo's wifi. This is expected of course, since your wifi connection is on Solo's wifi. What Solex does (and the 3DR Solo app) is bind its own process to the wifi connection (which is to the Solo). So any internet connectivity has to be provided through 4G, Bluetooth tethering, etc. The rest of the system, crucially, is unaffected. So I'd like to clarify what you mean by "losing internet capability". Solex is definitely not able to deny your entire phone access to the internet. No app is, really.
Thanks,
Kelly
