In this episode, we take a close look at wireless communication hardware inside laptops, focusing on how to identify, remove, and replace mini PCI Express or M dot 2 wireless cards. You’ll learn about antenna connections, slot types, screw mounts, and compatibility considerations when dealing with dual-band and Wi-Fi 6 modules. We explain the difference between onboard and removable wireless cards and why it’s important to follow manufacturer instructions for static safety and device reassembly.

Wireless hardware often appears in exam questions that describe partial functionality, such as missing wireless connectivity or dropped connections after a repair. Understanding how wireless cards work inside mobile devices helps you troubleshoot not only hardware failures but also misconfigurations at the firmware or driver level. This episode also clarifies which terminology—such as WWAN, WLAN, and Bluetooth—you need to recognize for the Core 1 test. Brought to you by BareMetalCyber.com.
