MT-MR3040 after install I cannot see it anymore

I just try to install the pirate box on MT-MR3040 but via Wifi because I am on MAC and I have no ethernet connection on my laptop

after a few minutes the router rebooted and then I let il go on with the installation for more then 45 minutes but I still cannot see it on the list of available routers

so impossible to connect and to go in with the installation

any idea what should I do?

thanks
