The correct answer is D. Incorrect channel. When two access points operate on the same frequency and the same (or overlapping) channel, they interfere with each other, causing co-channel interference or adjacent-channel interference. This results in packet collisions, retransmissions, and intermittent connectivity. The…

Explanation
When two access points operate on the same frequency and the same (or overlapping) channel, they interfere with each other, causing co-channel interference or adjacent-channel interference. This results in packet collisions, retransmissions, and intermittent connectivity. The fix is to assign each AP a non-overlapping channel (e.g., channels 1, 6, and 11 on 2.4 GHz). DNS errors would prevent name resolution but not connectivity; SSID mismatch would prevent clients from associating entirely; encryption type mismatches would prevent authentication, not cause intermittent drops.
