I want to know should it show I have many many ports open  some going to phone numbers not mine? I don’t understand this stuff. I believe someone is using my Wi-Fi and my cell phone account somehow using lot of data can anyone help me?

Sure we can check on the connected device list on the modem interface if you are using gateway combination of modem and router to access modem interface or GUI. Could you please help me with your modem model number to check on this.


I only use for wifi firestick tv my iPhone is different carrier I don’t understand when fing shows open ports some are peoples phone numbers my common sense says if I only one using why would phone numbers appear open ports and lots.of network's   I appreciate your help Kathryn
