wireless – Automating handshake capture to decrypt 802.11 frames

Networking newbie here.

I am running some experiments on IoT devices for which I need to capture the handshakes of the devices on my network in order to decrypt the frames I obtain through monitor mode. So far, I have been capturing the handshakes and manually inspecting some of the packets for analysis through Wireshark / Tshark. I am trying to automate the process by doing the following:

  1. Deauthenticate device using aireplay-ng.
  2. Capture handshake using airodump-ng.
  3. Start capturing packets using tshark.

I was wondering if it is possible to use the already captured handshake (step 2) to decrypt the frames instead of having to capture the handshake in Tshark itself.


Is it possible for me to deauthenticate a device and then successfully capture its handshake in Tshark?

Please keep in mind that I am attempting to automate this process, so I need to know what would make a proper pipeline. I also welcome suggestions if there’s a better way of doing this.

Thanks in advance!

wireless networking – Windows 10 machine periodically shows Wi-Fi as “no internet available”, even though other devices work fine. How to debug?

I’m using a brand new Dell laptop with Windows 10, connected to a WiFi network. Periodically the machine indicates the Wifi connection as “no Internet available”, at which point I cannot even log into the router’s admin page. Reconnecting to the Wifi usually helps restore connectivity. All other devices are working fine.

How do I debug this issue to figure out what’s wrong?

networking – Wireless and Wired networks don’t work

I have this issue with my Ubuntu budgie 20.04 which both wired and wireless networks don’t work any more. I had this problem with wireless before and I reinstalled the os to fix it! It worked fine for a month but slowly the wireless network got disabled in middle of work and now after many restarts and shutdowns, it may work for 1 minute! today the same is happening with the wired connection but The odd thing is that the problem is only with the Ethernet cable connection and when I use usb and my mobile usb tethering option, my laptops internet works fine! I don’t know whether it is software or hardware and after many searches and command I couldn’t figure out the problem. Please help!

wireless – Raspberry Pi 4B won’t connect to WiFi

I have Ubuntu Server 20.04 on my Raspberry Pi 4B 2GB, which I’m using as my AirPlay receiver. I was connected to my WiFi using NetworkManager, but it was suddenly disconnected. I have a Raspberry Pi 3B+ using Ubuntu Server, too but it wasn’t affected.

When I used nmcli dev wifi connect <SSID> password <password> I get the error saying “secrets were required but not provided”, even with the --ask option.

I tried using Netplan based on this solution, but WiFi remained disconnected.
