I've heard the Lynx WiFi has some issues. It might be better if you turn that off and connect to the IFD WiFi. It should send out the ADS-B information for ForeFlight. For the IFD to display ADS-B traffic and weather, it has to be receiving it over a wired connection from the Lynx.

I have an Avidyne MLB100 connected to an IFD540. Foreflight gets is information from the LIO WiFi network that is the default configuration coming from the IFD. 

ipad connects to wifi #2 (separate wifi newtork, channel 11). When connected to Lynx (separate wifi newtork, channel 1) I see ADS-B device on Foreflight.

I'm not sure I can turn off Lynx wifi. My original post may not have been clear: 3 separate wifi networks, 3 different channels. 440 # 2 ( on its own wifi network) shows its receiving ADS-B weather but no ADS-B appears on ipad: only the IFD device.

No, you can't turn off the Lynx wifi, but it should not matter.  The earlier problems with the Lynx and IFD not reliably connecting with ForeFlight appear to have been a problem with ForeFlight, which ForeFlight has now fixed.  On my iPad, I can select either box's wifi network to connect to, and whichever one I choose seems to be pretty steady these days.

Not sure what you mean here.  Are you saying ForeFlight is not displaying ADS-B weather or traffic?  Or are you saying the display of traffic and weather is fine, but the device info ForeFlight identifies is not what you expect?

This doesn't work for me.

When WIFI is connected to IFD #1 or #2, FF shows neither an ADS-B device (devices page) nor ADS-B data (weather and/or traffic on map page). When FF is connected to Lynx WIFI, FF shows both an ADS-B device and ADS-B data (weather and/or traffic on map page).

What version of IFD software are you using?

I haven't found any of the WiFi modules real robust on either the Lynx or the IFD but I would recommend the following -

1) turn off the Wi-Fi on one of the IFDs so only one is in use, I'm pretty sure that is Avidyne's recommendation anyway

2) turn off the Lynx Wi-Fi if unable then change the Wi-Fi channel on the IFD that you will be connecting to, to do this simply change the SSID by appending a 6 or 11 to the end of the name, that will tell the IFD to use channel 6 or 11

My shop connected the Lynx wifi module to its own 1amp breaker so I can easily turn it off, your mileage may vary.  The reason I say to either turn it off or change the channel on the IFD is I have found that by default both devices use channel 1 for Wi-Fi and eventually one or both of the Wi-Fi modules will "hang" due to interference from each other.  The channel on the Lynx is not changeable (or at least without removing the module and programming it manually).

Thanks for your reply. I've done all this. No luck. Next up will be updating the IFD operating software.
