GrowCube failed to connect to WiFi

Sun

 I am trying to set up the growcube and I keep getting the following message. 

 “The device cannot connect to the WiFi named Airport Free

Wi-Fi, please check

1. Whether the WiFi name and password are correct
2. Whether the device is powered normally
3. Whether the WiFi network is normal”

I have checked all of these things. I have double checked the spelling and password of the network, and I have made sure it is a 2.4 GHz network. Can you help me?

The wireless modem of GrowCube device is 802.11b/g/n protocol standard and cannot be modified, and does not support 5Ghz band.

Therefore, the GrowCube application and the GrowCube device cannot successfully configure the network because the router is configured with a wireless modem parameter that is not adapted to 802.11b/g/n or the router wireless modem parameter is 802.11a/ac/ax, so the network cannot be configured.

So we need to modify the router configuration. Such as ASUSRT-AC86U router setup method:

Enter the router management interface-->find wifi configuration-->professional settings-->select wireless modem settings-->up to MCS 7(802.11n)
