ADS-B

I'm flying behind 2 IFD440's with current navdata. A Lynx NGT-9000 feeds (I think) one of them (#2). Both 440's show they are receiving ADS-B weather but when I open Foreflight, the devices page shows only the IFD. No separate ADS-B "device" as I understand it should. Sometimes it appears briefly, but then goes away. I've read about possible wifi conflicts between the Lynx and the 2 440's, so I set 440#1 to wifi channel 6 and 440#2 to wifi channel 11. (Lynx is on channel 1.) I've communicated with others with a very similar setup and they do show the ADS-B device in FF. Any configuration suggestions?
