VIDEO TUTORIAL: https://www.youtube.com/watch?v=omhnVRJAMS8&t=4s

1) Hold the wifi logo longer than you think when prompted (5 seconds+)

2) Make sure your WiFi password / Name  is alphanumeric as symbols do not work well with the 8-bit architecture

3) Make sure your WiFi network you are connecting to is a mesh 2.4ghz/5ghz network OR 2.4ghz, it will not work with 5ghz. If you go into your router settings you can usually add a specific 2,4ghz

If you don't know what number 3 means, don't worry most WiFi signals are 2.4ghz or mesh out of the box, it is only if your router broadcasts 2 wifi networks.

4) Submit a bug report, we can check the log to see if anything else is an issue




We recommend using food-grade vacuum sealing bags because they’re BPA-free and made of polyethylene- like the ones made by FoodSaver

These bags need to be sealed with a vacuum-sealing system, which FoodSaver also makes. The alternative is sturdy resealable freezer bags, like Ziploc -made with low-density polyethylene.

Avoid using polycarbonate plastics, which releases the chemical Bisphenol A (BPA). This kind of plastic(s) can be found in some cling wrap, plastic squeeze bottles, take-out containers, multi-gallon water bottles, and plastic plates.
