Same WiFire issue here with a Pro 780.
I run out of ideas (and patience).
I tried so many things :
- Move the Traeger grill in house to be sure of wireless signal.
- Initiate pairing WiFire process using Samsung Galaxy S9/Android, iPhone 10, iPad devices.
- Initiate pairing WiFire process in airplane mode (without cell service)
- Uninstalled/Install many times Traeger app on Android (Version 2.0.13_2 (524) ) to clear app memory cache.
- Setup several 2.4GHz wireless SSIDs on my WAP (54 Mbps, 145 Mbps, 300 Mbps modes).
- Used a wireless repeater to get better signal.
- Setup simple/short SSID and passwords.
- I checked security mechanism on my WAP (e.g. ACL feature disabled).
- Restarted WAP many times.
- Tried QR code and no QR code paring processes.
- Powered-Off/On Traeger grills after each tentative.
- On controller, I went to MENU > WIFI INFORMATION; and hold IGNITE for 10-15s to reset the WiFi network settings on the grill controller --> I suspect my D2 firmware is too old (nothing happened)
Frustrating when you spend this amount of money (1300 EUR) for your first Traeger grill and not be able to use it (missing features on Pro 780 without the app).
TECHNICAL INFORMATION :
SW VER: 01.00.10
CONFIG VER: 03.003
Signal strength is around -50dbm
