I am running through the initial setup of my WEM3080. I have used by app and web. I get the same result both times. I access the device. See all of the interfaces and settings. Go to assign my wifi 2.4ghz SSID and password. The device sits for a second (with the 20 sec countdown), and then nothing. When I again try to connect to the local iMeter SSID either on my mobile or my laptop, the connection starts then drops. It shows back up a few seconds later. Over and over. I can not successfully get the device to retain my SSID for my home or keep a solid connection to check if the settings are correct. 

Thoughts?

Let us only use the web do the wifi configuration for testing

Please let me know 

1 what is the status of the Wi-Fi LED after you set the wifi credential?

2 After you click "save” when you set the wifi credential by a web browser, it prompts that the configuration is successful, yes?

3 when you connect the ap ,please visit

please also let me know which "SSID" is the ap name of your WLAN  and what is its "Signal" value.
