For background on 2.4G and 5G Wi-Fi, please read this article.
As we discussed earlier, YI Home App uses QR code to deliver the Wi-Fi information to the camera.
Pairing the camera with Wi-Fi turns out to be the most difficult part of YI Home camera user experience. Among the pairing failures, a big part of the problem, is due to 5G Wi-Fi used.
Current YI Home Camera models do not support 5G Wi-Fi. The picture below shows what user will see when she chooses a 5G Wi-Fi network.
Many latest routers in the market now support dual band Wi-Fi (both 2.4G and 5G). By default, it will provide two different SSIDs, one for 2.4G, one for 5G.
Some routers support a feature called “smart config“, when enabled, will only provide one SSID. Depending on the client, it offers the optimal frequency for the client.
This creates some confusion for YI Home Camera users. When connected to such router, the App may detect that it is using 5G Wi-Fi, and ask the user to switch to a 2.4G Wi-Fi.
When this happens, if you are sure that the router behind the SSID supports both 2.4G and 5G Wi-Fi, please click “Connect to Wi-Fi”. Chances are the camera can connect successfully through the 2.4G Wi-Fi.
