Adrian, We're working to turn on ANI debugging and will post results.
Check out these pics to get an idea of the environment and equipment we're talking about--this is not the typical office setup. At both these sites we don't see the issue on 3Ghz and 2.4Ghz, but likely due to being in quiet part 97 space outside part 15. We only see the issue on 5Ghz where we are operating in part 15 space at these sites and symptoms started with Barrier Breaker upgrade. All devices are Ubnt Rockets with 120 Sector panels. Let's just say it is an RF congested area. https://drive.google.com/folderview?id=0B2bEy75HhwWhflByWjhfOXdYMnBuSGFBYnByV0hBU2loNS1Cd25Ia0tJSXg3UFNfZ3JKaWc&usp=sharing https://drive.google.com/folderview?id=0B2bEy75HhwWhfkFuY05fX1BGTllVeEVUVGRNcEx6b1JXNHJYbGV1Yzh6LTB3OFFLbGFJeTA&usp=sharing Joe AE6XE On Sat, Oct 10, 2015 at 6:07 PM, Adrian Chadd <adr...@freebsd.org> wrote: > Hi, > > Can you turn on ANI debugging in ath9k and capture what it's doing? > > I've seen this happen on some other outdoor stuff with AR9380 but I > think their setup is more "the interference is terrible".
