*DING* There's your problem. It doesn't matter if you can link and pass
traffic. If **ANY** other signal is detected in the extended channel, the
AP is *REQUIRED* to cease operation @ 40MHz. This is why it is nearly
impossible (outside a shielded lab) to get 40Mhz mode in the 2.4GHz band.
SOMETHING is going to step on it -- neighbors, bluetooth, cordless phone,
leaky microwave oven, baby monitor, RC toy, ...
