Can Wireshark capture packets from other devices?

Can Wireshark capture packets from other devices?

In wireshark we can capture packets of only our devices in TCP protocol while packets of other devices are captured as broadcast packets in ARP protocol.

Can you see what someone is looking at on your WiFi?

1. WireShark. Wireshark is a popular packet capturing tool, design especially to see what people are browsing on a network in real-time. Once you start the software, it shows the IP address of all the devices on your network.

How do I see other devices in Wireshark?

4 Answers

1. Launch Wireshark on your computer.
2. Set WPA key in Wireshark’s settings.
3. Start the packet capture on your wireless interface (in Linux you should be putting your wireless device in Monitor mode to gather all packets)
4. Force the target device to reassociate with the AP (turn wifi off/on, turn AP off/on, etc)

How do you sniff data on a network?

To capture network traffic, you can use tcpdump. This is a packet sniffer that can observe and record network traffic on an interface. In the following example, we capture 1,000 packets using tcpdump. An easier way to analyze network traffic is to use an actual network traffic analyzer, such as Wireshark.

Why can’t I capture other device’s packets?

I’m guessing it may have something to do with the fact that my router is using WPA2 encryption, instead of being unencrypted (like an “open” wireless network). Or maybe I need to use a wired connection (rather than wireless connection) when connecting my packet inspection computer to the router.

How are packets sent between WiFi access points?

In a standard (i.e. non-AdHoc) WiFi network the answer is yes, packets sent between WiFi Stations will go via the Access Point. As allen-smithee mentions, the analogy probably makes more sense if you think of the AP as a switch, with the “association” between each station being a cable.

Is it possible for two devices to connect to the same WiFi?

NB: If the client A & B are close enough to hear each other, it would be possible for them to communicate directly, but implementing the communications like this would introduce a lot of complexities. A great primer on WiFi is Matthew Gast’s book 802.11 Wireless Networks: The Definitive Guide (see the link for a “copy”). In particular Chapter 4.

Can a wifi adapter be used as a capture adapter?

And this is despite the fact that I put a tick in the check box for promiscuous mode, for my wi-fi adapter in the Wireshark adapters settings, and made sure to select that adapter as my capture adapter. An yes, I’m using the latest NPCap driver installed by the Wireshark installer. I’m not sure what’s wrong.
