The sequence of events isn’t completely clear.
You say you went to the activation site and successfully registered the gateway.
Then you got on to the TTIG access point via WiFi and configured it for your home WiFi.
Actually, it was probably wrong for me to post my problem where I did. I don’t think what I have is a TTIG. The package says: “The Things Gateway, Frequency 915 MHz.” This probably addresses the point you raised later about the TTIG having no ethernet port. The unit I have (TTG) has an ethernet port. I am less than a week old in this, so I’m still struggling with all the acronyms and what they mean. Sorry about that.
After connecting my laptop to the TTIG (or is it TTG) access point, the connection to the internet was lost.
I continued configuring my home WiFi anyway. After the Configure button was hit, the following message appears quickly on the screen and disappears:
“The settings have been sent successfully to your gateway!
Let’s see if it can reach the internet and activate itself successfully.”
The message “This site can’t be reached …” appears immediately and stays on the console window.
What device did you try connecting via Ethernet, given that the TTIG doesn’t have an Ethernet port?
I alluded to this earlier. My TTG has an ethernet port.
Is it possible you left your computer in some sort of network void of thinking it was connected to the TTIG access point which won’t exist anymore if it is genuinely connected to your WiFi?
Probably, but I’m not sure.
What is the LED on the TTIG doing? What does the gateway console say?
On the unit, LED 1 is solid blue; 2nd LED is blinking; the rest are off.
