So I tried the red config button- logged into the wifi logger SSID and checked, everything was correct. I reset it and still would not connect to my network. So I rebooted my router and about 10 minutes later the LED was steady green and uploading to the sites again. I have about 8 other wifi devices that are always on this same network, and none of them were having issues, only the WiFi Logger.
I don't understand why, in the middle of the night, after being on-line for weeks, it just decides to just drop off the LAN.
