Permenent connection with certificate: Access issues with Android 4.(version)

Android 4.(version) introduced a bug that prevents proper connection to wifi networks polimi-protected / eduroam.

Devices may stop working after a system update that introduces the bug.

For more information

Error message: "Unable to connect to the selected network. The network may no longer be within the range. Update the list of available networks and try connecting again."

You need to update the driver for the wireless card to the latest version available on the manufacturer's website. For Atheros cards refer to website

After installation, the Windows7/Vista configuration tool  gives error (Failed POLIMI-protected ... retrying ...) and the computer does not connect either to "POLIMI-protected" or to "eduroam".

Update the operating system (Windows Update) and the wifi network card driver. Rerun the tool.

When I connect to the network "POLIMI" and I try to download the Mac OS X Lion "POLIMI-protected" or "eduroam" configuration I get an empty file (zero bytes).

Newly connected to the network "POLIMI", with Mac OS X Lion, it automatically opens a window "mod" of Safari, before continuing close it and open Safari manually .

I am connected correctly but my browser does not load the page.

You must check that you have set the dynamic assignment of the IP address in the network configuration and, in particular, that you have not manually set up external DNS of the Politecnico (for example,, etc.).
