To change the WiFi network (SSID) or password, the WiFi connect
mode must be forced.
To force the WiFi connect mode, disconnect the NT USB from the
power supply and connect it again while holding down the button.
The module will initially show a red light, press and hold the button
until the light changes to solid purple. At this point the module will
be in WiFi connect mode generating the corresponding network
(MIFarho_xxxx).
Then follow the instructions in section "1.2 WiFi connect mode".
If the NT USB is in No remote mode [steady orange light] check that
the router has access to the Internet, for example by accessing the
Google search engine website with a web browser from a device
connected to the same WiFi network as the NT USB. In case of
problems with Internet access, contact your provider.
If there is no problem with the Internet connection try disconnecting
the NT USB from the power supply, wait a few seconds and recon-
nect it.
Check for a rmware update by following the steps described in "2.
Firmware update".

If the problems persist, it may be that the servers are under mainte-
nance or it is a one-o problem.
In this case only the remote access will be interrupted, the rest of the
NT USB functionalities will remain operational.
The service will be restored automatically without any action from
the user.
