Intermittent Wi-Fi issues specific to one area with admitted weak AP coverage directly point to insufficient signal strength from distant access points, causing drops and poor performance.
Wired RJ45 ports nearby not working suggests a separate cabling or port issue, but the Wi-Fi problem aligns with coverage gaps rather than brute-force attacks, malware, or disabled ports, which would not be location-specific or tied to weak signal.

A DHCP reservation maps a specific IP address to a device's MAC address, ensuring the PC always receives the same IP address while still using DHCP.

A sandbox in virtualization allows testing an application in an isolated environment to observe its behavior without affecting the host system.

Type 2 hypervisors run as applications atop a host operating system, relying on that OS for hardware drivers and resource management rather than interfacing directly with the hardware.

Even when the cable is properly connected and the laptop display mode is correctly set, the projector will not show an image unless it is set to the correct input source. If the projector is set to a different input than HDMI, it will not display the laptop's output.
