You are troubleshooting a client problem with a 2.4 GHz WLAN connection. The client is experiencing surprisingly low data rates during the work day. You analyze the workspace outside of business hours and detect a strong signal with a typical noise floor at the client location. During working hours, the user works with a laptop in the area and uses an external USB hard drive for continuous data access.

Based on this information, what is the likely cause of the problem?
- A. The AP is overloaded during the work day
- B. The laptop has a falling wireless adapter
- C. The external hard drive is USB 3.0 and is causing a significant increase in the noise floor when in use
- D. The drivers in the laptop are corrupt
