The error, that you see on a screen, may appear because of some settings of your Wi-Fi router.
1. At first, try to reboot your router. If it does not work, you should check MAC Address Filter on your router, it should be off. If it is on, you need to add to this filter MAC Address, that you see on the screen and make sure, that DHCP on your router is on.
You may also contact a person, who is responsible for settings of your router, to make these settings and solve the problem.
2. Make sure your network is 2.4GHz. LaMetric doesn't support 5GHz networks.
