I just repeated setup to look. press the setup button not the reset button. connect to the new AP ‘MiniHub…’. on the bottom of the page 192.168.4.1 you will find the datas of your GW. scroll down the page.
after that you need to connect to your own network by clicking your wifi on the list. put in the credentials and save. after a reboot and some time the gw will be connected to your own router. then you can start in the TTN console as described in recent mails before.
I hope, you can figure all out.
