A user is reporting that they cannot connect to the wireless network from their office but they were able to connect yesterday. Which of the following would be the MOST likely reason?

Question

Options

• ARadio switch on laptop is enabled
• BRadio switch on laptop is disabled
• CChannel interference
• DUser is too far away from the access point

• A
  3% (1)
• B
  92% (34)
• C
  5% (2)

Explanation

Since the user could connect the day before, the network infrastructure itself is unlikely to have changed. The most probable cause of a sudden inability to connect is that the laptop's physical wireless radio switch was inadvertently turned off - many laptops have a hardware button or function key that toggles the wireless adapter. When the radio is disabled, the system cannot detect or connect to any wireless network. An enabled radio (A) would allow connectivity, not prevent it. Channel interference (C) would more likely cause degraded performance rather than a complete inability to connect. Being too far from the access point (D) is unlikely if the user is in the same office they were in the previous day.
