It's a 2013 T430u with an Intel Centrino Wireless-N 2230 chip. It only supports 2.4 GHz, and not 5 GHz. I use a second, external USB WiFi dongle for Wireshark and other uses. It's six years old and great to use for more than I thought it would be.
For normal dongles a search for “Anadol Gold Line Wifi AWL150 Micro 150Mbit/s USB WLAN S” shows the one I use in various bsds/linuxes with no problems.
Both re0/run0 chips.
It all depends too if you are in managed mode or monitor mode. See this: https://github.com/nmap/npcap/releases
Here's some more info. on modes and your capture setup: https://wiki.wireshark.org/CaptureSetup/WLAN/CaptureSetup/WL...
