I've followed the steps for 2.2.1 here:

As well as the steps for Mali DDK here:
https://wiki.tizen.org/wiki/Enable_3D_Acceleration_on_Tizen
Both of these processes have completed successfully, and the device shows it is running 2.2.1 with 3D acceleration. However, wifi still does not work. I can see all available networks and am able to enter a password, but the device displays "connecting" briefly and then does not successfully connect. Are there any further steps or resources available? The device will successfully connect to an unsecured network.
