probably driver related, if you installed the proper drivers in the requirements then whenever windows tries to search online for the drivers simply click on "Skip obtaining driver software..." . it should proceed to installing the locally found drivers
BTW is the device now able to boot properly now?

Note: When the setup wizard start, the router is correctly recognized on device manager(windows).
Thanks for helping.

if it failed at user information,
disconnect the mifi, remove and reinsert the battery, power on the mifi but don't connect it to the PC
is the mifi able to boot fully or does it get stuck somewhere?
