Did you check your power supply? Try a different power supply.
You can also try the following (no guarantees):
Get a usb a to ethernet adapter and plug it into the USB port on the mini.
Plug the ethernet cable into a/ the router that has the network to which your computer / device running the ASIAIR App connects.
Turn on ASIAIR, give it a few minutes.
Go to device. Make sure it's on the correct network. Launch ASIAIR App. See if it finds the ASIAIR .
If it doesn't - go to your router admin page and see if you can find the IP address it allocated to the ASIAIR.
Use that IP address and connect via IP on ASIAIR App to see if it works.
