What is DFS, and does the WAP-C3 have it?
Yes, the WAP-C3 supports DFS. FCC regulations require devices to switch to a different channel if aircraft radar presence is detected. This is called Dynamic Frequency Selection (DFS). DFS channels in the 5.0 GHz spectrum are 52 – 140. Non-DFS channels are 36 – 48, and 149 – 165. If there is radar presence, near an airport for instance, the WAP-C3 will automatically switch over to an open non-DFS channel. Many client cards do not support the higher channels, 149-165. Therefore, to avoid channel switching, set the WAP-C3 to a lower channel, 36 – 48.
