I have been successfully connecting my Cerbo GX to a mobile Wi-Fi hotspot using an iPhone 14 with WPA/WPA2 security and a password. When I attempt to connect it to an old Google Nexus 4 Android phone, the connection only works with an unsecured network. With the WPA2 and password Cerbo GX refuses to connect.
I only come here once a year and I don't want to leave the system disconnected and unattended for a year. I am also uncomfortable leaving an open Wi-Fi hotspot for anyone to join. I can't leave the new phone here instead of the old one as it's my work phone, not a personal device. If you had a similar experience and know what could be the cause, please let me know what to try.
I also tried to set up USB tethering instead of the Wi-Fi hotspot. It works fine on the PC, but I don't have any clue how to set it up on Cerbo GX. The documentation simply says that it's great when it works, but one shouldn't count on it and sends to search the internet for my device configuration. My phone is configured, but how do I make Cerbo GX use it's USB tethering? There is no option in the remote control, except for the GSM modem, but that is not detected.
Any help is much appreciated.
