A SOHO would like to limit usage of their wireless network to two computers. Which of the following would be the EASIEST way for a technician to accomplish this?

Assigning static IP addresses does not prevent other devices from connecting to the wireless network using DHCP or their own static addresses.

Reducing signal strength can limit coverage area but cannot precisely restrict access to exactly two devices, as nearby users could still connect within range.

Disabling unused ports applies to wired switch ports and has no effect on wireless clients connecting over Wi-Fi.

MAC filtering works by configuring the wireless router with a list of allowed MAC addresses, one for each permitted network adapter. Only devices whose MAC addresses are on the approved list are granted association with the access point, regardless of whether they know the Wi-Fi password. This provides a simple, direct method to allow exactly two specific computers and block all others.
