Hi Abacus,
Thank you for asking about the feature of the Samsung refrigerator. Yes, you can use wi-fi on this model by downloading the SmartThings app.
I highly suggest checking the user's manual on pages 42 to 43.
Here's the user's manual link: https://downloadcenter.samsung.com/content/UM/202112/20211206163818892/FDR_RF8000B_DA68_04402B-00_EN_MES_CFR.pdf
