Question

A small business owner modified his wireless router with the following settings:

PERMIT 1A:2B:3C:4D:5E:6F
DENY 6F:5E:4D:3C:2B:1A
After saving the settings, an employee reports that he cannot access the wireless network anymore. What is the MOST likely reason that the employee cannot access the network?

Answer 1

The employee likely cannot access the network due to MAC address filtering on the router, which is either allowing only one specific address while denying another, or incorrectly denying an allowed address.

Step-by-step explanation:

The most likely reason that the employee cannot access the wireless network anymore is due to a MAC address filter set up by the small business owner on the wireless router. The settings indicate that only a device with a MAC address of 1A:2B:3C:4D:5E:6F is permitted to access the network, while any device with a MAC address of 6F:5E:4D:3C:2B:1A is denied access. If the employee's device MAC address matches the one that is set to deny, it would prevent the device from connecting to the wireless network.
