WiFi符號隔離多左個感歎號，顯示互聯網可能不可用，modern有問題定係router有問題，可以點解決？

1. Router is the problem (Note - if the modem is connected with a router, then the only issue that can happen is out of internet connection).

2. Restart either or both the router and devices. Also - removing internet settings on the devices helps.
