Did it right this time: completed the full channel survey (74/74) FIRST, let the
data choose. Survey proved DFS channels are 4-5x cleaner here (2-3% busy) than
non-DFS (149/157 = 12-28%, the property's worst). Per Howard: built the plan on
the 8 clean DFS 40MHz blocks (52/60/100/108/116/124/132/140), per-AP locally-
cleanest + neighbor graph-colored -> 0 co-channel, 3.5% avg busy. Applied to 72
non-mesh APs (width 40 too); mesh excluded; voice nudged back to 5GHz.
VALIDATED: 5GHz retry 8.7->3.8 avg (-56%), median 8.2->2.1 (-74%); 2.4 ~baseline;
satisfaction median 99; voice 31/31 (17 Poly on 5GHz, 3 coverage-cases on 2.4);
all 72 APs holding DFS, 0 radar vacates.
Kept tonight: 2b (2.4 power) + DFS plan + BSS-transition. 6GHz still WPA3-blocked.
auto_upgrade still OFF. Follow-up: recurring dfs-check radar monitor.
