FitBit Aria 2 Not Connecting to PlusNet

[#1]

Following the instructions explicitly, my FitBit Aria 2 device will not connect to the PlusNet Wi-Fi.

• The mobile app connects to the device
• The device can see the Router
• Wi-Fi Password has been input correctly
• The Device times out from connecting to WiFi

I have tried all the trouble shooting steps including:

• Removing the batteries
• Removing the app
• Connect to another WiFi (mobile - which worked as it should)

FitBit's own help service have asked if the PlusNet router conforms to the follow standard:

• 802.11b/g/n frequency setting
• WEP / WPA / WPA2 personal security Automatic (DHCP) IP setup (static IP configurations are not supported)
• Both the network name and password must be no more than 32 characters long

These questions have been asked on this forum but not resolved

Assuming it's a Hub One, you could try splitting the 2.4Ghz and 5Ghz frequencies and seeing if that helps.

I had a similar experience with and echo that never got resolved until I got a different router, sadly.
