Connect Range Extender WN3000RP to a hotspot

Hi

I reactivated an old WN3000RP to get in connection with a hotspot.

There is no problem to get connected with the Range Extender WN3000RP, I'm able to reach it with http://mywifiext.net/ and to find the hotspot I want to get and get connected.

The problem: the get properly connected to the hotspot I've to provide an username and password.

mywifinext.net has only the password to input. Of course, without user I'm out.

Is there any solution? Driver? Workaround?

Thanks for any help.
