Can some neighbor with his laptop capture the wireless traffic packets which I send and receive from my router, if he is not connected to my WLAN?
Can someone connected to my WLAN and without access to the router capture the wireless traffic packets I send and receive? And if so, can he read their data content?
- You don't have to be connected to a certain WLAN in order to capture packets from that wireless network.
- You also can capture packets if you are conntected to a WLAN (I'm not quite sure about this point, but I think this should be possible if the hardware is able to do so).
- Unless you did not set up a security/encryption scheme for your router, those captured packets are rather useless for sniffers. Encrypted packets are only readable by the sender and the receiver (client, router). Hence it is also not possible to read packets from users on the same network.
