Intermittent loss of WIFI can be attributed to a couple of different variables. For the best possible WIFI signal, you'll want to eliminate any other networks that may also be active in the aircraft, or in the hangar if the aircraft is inside.
Here is a list of known interferences to look out for when attempting to establish an IFD WIFI connection:
If you have lost WiFi and/or Bluetooth after an IFD Software Update, please check the tail number is still configured in your Main System Configuration page. If not, please re-enter your tail number to include the country alphabetical indicator (N for US, C for Canada etc.) After a power cycle, your options should repopulate. If not, ensure your tail number matches the tail number from when the unit was ordered, to include any dashes or special characters. This configuration is directly tied to the options so if this number is not per the order tail number you must contact Techsupport@avidyne.com to have a new options file created for the desired tail number.
If this does not repopulate your options, check your System Tab in the Aux Menu to verify Options Enabled in the Software Status page by toggling the Status LSK (line select key) on the bottom left of your screen . You should see the options ENET/IO and BT both highlighted in green, with white font if the options are enabled. If not, the options will appear in green font, not highlighted. See example below.
If your Bluetooth and WIFI options here (ENET/IO and BT) are not enabled, please gather your tail number as configured in the above example, and #1 and #2 IFD serial numbers and send this information to firstname.lastname@example.org with subject line Options Enablement File request. Please ensure to specify which IFD is #1 and #2, as their positions matter when creating the file for you.
Our Pilot Support team will send you a file titled with the tail number as shown in your Main System Config page, to re-enable your options for you. If these options are highlighted in green and appear to be enabled, please ensure no other cellular or WIFI networks nearby are interfering with your WIFI network for best function of the WIFI and Bluetooth options.
If none of these variables are present in your aircraft. Please submit a ticket to email@example.com and include as much information as possible regarding your issue, including that you have already read this article, aircraft tail number, and the IFD flight logs. Dealer Support can gladly help narrow down what may be going on inside the unit once you've isolated the problem. Upon reaching out to Tech Support, we will provide a Google Drive upload link for your logs.
