I recently upgraded my home to a mesh network that is supposed to supply dual-band signals. Unfortunately, the Thermoworks Smoke couldn't find the 2.4ghz signal. It was really frustrating considering how much the gateway costs to let you access your cook temps via smartphone no matter where you are. So I found this little guy on Amazon and for yet more money into this system, it finally is secure and works great. So if you are having a similar problem, just get a repeater for your router that only can broadcast in 2.4 and you'll be good to go. Just thought I could save someone some time and energy with this fix.
