The correct answer is C. Enable MAC filtering. In an apartment building, neighbors can easily detect and connect to a router left with default settings (default SSID, no password or weak encryption).

Question
A user installed a new SOHO router and new wireless NICs to increase their transmission speed from 802.11b to 802.11g with the manufacturer's default settings. The user lives in an apartment building and is still experiencing slowness to the Internet after the installations. Which of the following is the MOST secure option that a technician could implement to resolve this issue?
Options
- AHide the SSID
- BAssign static IP addresses
- CEnable MAC filtering
- DDisable the WAN port

Explanation
In an apartment building, neighbors can easily detect and connect to a router left with default settings (default SSID, no password or weak encryption). Unauthorized users consuming bandwidth would explain the continued slowness despite the 802.11g upgrade. MAC filtering is the MOST SECURE option among the choices because it explicitly whitelists only known, authorized devices - even if someone obtains the Wi-Fi password, they cannot connect without a matching MAC address. Hiding the SSID provides only minimal obscurity (SSIDs are still discoverable with simple tools). Assigning static IPs does not prevent unauthorized access. Disabling the WAN port would cut off internet access entirely.
