NEW QUESTION 44
Why should band steering algorithms allow stations to connect to the 2.4 GHz band after some number of ignored Probe Requests?
- A. Because some clients are persistent clients that will not move on to the 5 GHz band.
- B. Because the AP will experience a buffer overflow if they do not eventually respond with a Probe Response.
