I consider myself a reasonably proficient user but this has me beat!
I’m using a Pixel 5a running Android 11. My wifi networks are 5G biased but support 2.4G. I have a bunch of IoT devices connected to the Wifi network that I’m trying to use.
I connect my phone to that network though it connects to it at 5G and I’m unable to force it to connect at 2.4G
I’m using the Samsung SmartThings app. I’ve tried many times to connect to the fridge and failed.
I put the fridge in AP and can see a SMART-DEVFRIDGE or similar wifi network appear on the phone.
The app is unable to find the fridge.
I’ve disabled the cellular modem as that has helped with other devices. I’ve tried another wifi network that’s provided by a different router but that also prefers 5G.
The 2.4G vs 5G may be a red-herring because the SmartThings app isn’t discovering the Fridge even though I’m confident the fridge is in AP mode.
Are there any tricks? I’m beyond wanting this for convenience and it’s become a battle of wills
At a guess you have tried all the connection methods recommended? I had a brief read and there seems to be some button pushing and door opening involved
Not sure which form of connection your fridge has but a quick read says for non family hub fridges you have to push the door alarm button when door open then button to activate AP mode, I guess you already pushed the door alarm button to unlock the temperate control panel ?
Your fridge then needs to be seen on your WiFi network, if you are unable to switch off 5 ghz WiFi leaving only 2.4 ghz have a read at this thread
The 23 cu. ft. French Door Refrigerator in Stainless Steel, US model RF23HCEDBSR isn’t listed as a supported model in Smart Things after checking my list. I see that the US White model RF23HCEDBWW is listed. You may want to reach out and put in a support ticket to see if your specific model has compatibility within the Smart Things application.

I have tried the Samsung E-Smart Ref app too and been unsuccessful with it.
The fact that the fridge is creating a wireless network that I can see only my phone only when the fridge in in “AP” mode (DEV-SMARTREF) suggests to me that the issue is either with my phone (I have tried another albeit another modern Pixel phone) and/or an issue downgrading to 2.4GHz wifi.
