Can I use Wireshark on my home network?
Yes. Wireshark can capture packets off of a WiFi network as long as the computer it is installed on has a WiFi transceiver and is in promiscuous mode. Wireshark uses the Airpcap standard for wireless packet capture.
Can Wireshark capture passwords?

Both very handy tools, Nmap allows you to scan an object for listening ports, discover services on a network and more. Wireshark lets you log network traffic and analyse it.
Is Wireshark a sniffer?
How does Wireshark work? Wireshark is a packet sniffer and analysis tool. It captures network traffic from ethernet, Bluetooth, wireless (IEEE. 802.11), token ring, and frame relay connections, among others, and stores that data for offline analysis.
Why does Wireshark only captures my traffic?
You need to set up the network interfaces you want to sniff the traffic on in promiscuous mode from Wireshark settings. If you don’t, you can only sniff the network traffic directly intended for your host, and not all the traffic on your network, as this is the way switched networks normally work.
Is Wireshark can be used to steal sensitive information over a network?
It can be used to analyze internal networks and network usage, debug application issues, and study protocols in action. But it can also be used to sniff passwords, reverse-engineer network protocols, steal sensitive information, and listen in on the online chatter at your local coffee shop.
Can Wireshark send packets?
Wireshark is not a packet generator, it captures and decodes packets. Look at other tools like Ostinato or scapy to replay captured packets or generate new packets.
