A technician is trying to identify the cause of an issue several wireless users are experiencing at an office.
The office is in a square-shaped building, with four 802.11b WAPs with omnidirectional antennas located in the four corners of the building.
Users near the center of the building report sporadic issues connecting to resources.
The technician checks the signal strength in the middle of the building and determines it is adequate.
Which of the following is causing the reported issue?
A.
The antenna types are incorrect, and unidirectional should be used. B.
MAC filtering has not been updated. C.
There is channel overlap of the access points. D.
The power levels are set too low on the WAPs.
C.

The reported issue is that wireless users near the center of the square-shaped building are experiencing sporadic connection issues despite the adequate signal strength in the middle of the building. The building has four 802.11b WAPs with omnidirectional antennas located in the four corners of the building.
Option A, suggesting that the antenna types are incorrect, and unidirectional antennas should be used, is not the cause of the reported issue. Omnidirectional antennas are designed to provide coverage in all directions and are appropriate for the layout of the building.
Option B, suggesting that MAC filtering has not been updated, is not the cause of the reported issue. MAC filtering is a security measure used to restrict access to a wireless network based on the MAC address of devices. If MAC filtering were the issue, all users would be affected, not just those in the center of the building.
Option D, suggesting that the power levels are set too low on the WAPs, is not the cause of the reported issue. If the power levels were too low, the signal strength in the center of the building would also be affected.
Option C, suggesting that there is channel overlap of the access points, is the most likely cause of the reported issue. Channel overlap occurs when adjacent access points are using the same channel, which can cause interference and lead to connection issues. In this case, the four WAPs are located in the four corners of the building, and there is a possibility that the channels are overlapping in the center of the building, causing the sporadic connection issues. The technician can resolve this issue by reconfiguring the WAPs to use non-overlapping channels or by adjusting the power levels of the WAPs to reduce interference.
