Which of the following can contribute to an AP association getting stuck?

• A. edge of the network's coverage range
• B. The user’s device battery is low
• C. The router’s LED is red
• D. The AP is in a different channel

Answer: (A)

Weak signal at the edge of coverage makes an AP association get stuck. When a client is far from the AP, the wireless link quality drops; frames get corrupted or lost, so the authentication/association handshake can’t complete. The client keeps retrying, waiting for valid responses that don’t reliably arrive, and the process stalls.

Other factors listed aren’t usually the root cause. A low device battery isn’t a direct barrier to forming the connection, the LED color is just a status indicator, and being on a different channel won’t inherently prevent discovery and joining once the client scans the available channels.
