A technician sets up a small wireless network, but it appears to provide less coverage than expected. Which of the following is the most likely cause of this issue?

Interference can degrade signal quality and speed, but it typically doesn't directly reduce the physical coverage area in the same way as low power, though it can make the signal unusable within that area.

Low power output from a wireless access point directly reduces the signal strength, resulting in a smaller coverage area and weaker connections for client devices. Increasing the transmit power can extend the range and improve signal penetration through obstacles.

An incorrect protocol would likely prevent any connection or cause severe communication issues, not just reduced coverage.

An incompatible access point might not function at all or would have specific compatibility issues, not necessarily just poor coverage.
