If the change is only about removing the weather radar band (5600-5650), the change should be - (5490 - 5730 @ 160), (24), DFS + (5490 - 5570 @ 80), (24), DFS + (5570 - 5590 @ 20), (24), DFS + (5650 - 5730 @ 80), (24), DFS The second rule explicitly states that channel 116 remains available for HT20. If this level of strict correctness is not needed, rule 1 and 2 combined would be - (5490 - 5730 @ 160), (24), DFS + (5490 - 5590 @ 80), (24), DFS + (5650 - 5730 @ 80), (24), DFS Cheers Zefir -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
