Hi, I just bought a zyxel fwa 510. I put in a mobile Free Sim card. I'm in the countryside, seeing red, no internet access. The APNs I found don't seem to work, reboot reset = ditto. The Free mobile Sim is activated and works on an Android phone, so it doesn't come from it. When I try to update the system with the latest update, it refuses me. What should I do, I'm stuck. Thank you for your answers and help.
