Here's an observation about my setup ...
My MAK Grill Mobile WiFi module is connected to my router at 2.4G
My Android tablet is connected to the router at 2.4G
My Android phone is connected to the router at 5G
My PC is connected directly to the router with an ethernet cable
As you pointed out Mike the 5G range is much shorter. My router is about 50 ft from my MAK with 1 interior wall and 1 exterior wall. Until recently there were times when I could not connect to the WiFi module even though I could ping the module and it was alive. All my devices (tablet, phone, PC) are usually within 20-30 ft of my router.
Not sure if this information is meaningful to anyone but I thought I would share my environment. I will be smoking/cooking a pork loin roast this afternoon and I'm hoping that I can connect OK since it's raining outside - yes it does occasionally rain in California ... I'll report on my status later today.
So this is my understanding of how the WiFi module (MAK Grills Mobile) works ... Please correct me if I'm wrong.
The WiFi module connects to the server through my router at 2.4G
I log into the server using an APP on one of my devices and connect to my MAK Grills Mobile account
This allows me to communicate from my phone/tablet/PC APP to my MAK Pellet Boss via the server and WiFi module
Am I correct in presuming that the Pellet Boss communicates via the WiFi module through the MAK Grills Mobile server to my APP? If so - then if I can ping my WiFi module, I would think that connection issues might have something to do with the MAK Grill Mobile server? I'm convinced that there is no issue with my WiFi module and/or APPs on my devices.
Maybe someone with more knowledge than me will chime in and set me straight
