I noticed my Aurora WebLink was offline, so I pulled the plug for a few seconds & plugged it back in. Then I noticed it didn't connect to the Wi-Fi. I then reset it & was able to connect to it as an access point. But when I went to 172.20.10.1, all I got was "404: File not found". Is this something I can do to fix this? Is the SD card bad? Or is the AWL bad & needs to be replaced? Have not contacted the dealer yet. What is the warranty on it?
