I am able to see the ad-network created by the N9 from both a Dell Streak 5 (running Cyanogenmod 7) and from the N900 running Fremantle (CSSU Testing+KP).

However, none of them are capable of connecting to the network. In the Dell Streak I see that the device is waiting to receive an IP while the N900 gets stuck trying to connect.

Every configuration parameter in the N9 Hotspot application are set to default, so I don't know what could be the problem.

Worst thing is that after activating the Wifi Hotspot application and trying to connect, even turning it off, the N9 is unable to connect to any Wifi network. A reboot is needed to get the wifi working again.

I have also checked that my laptop is capable of connect and use the Internet from the N9 Hotspot with Windows 7 64 bits.
