I use an Acer 4750 laptop, which has a bcm43225 wifi chip. In Ubuntu 12.04, each time I boot up, my laptop's wifi will automatically turn on, and the 12.04 use kernel 3.2 However, when I upgraded to 12.10, 13.04, using a newer kernel, I found my wifi not automatically turning on during startup. But its function is normal:I still can turn on it with Fn key.
I have experimented it, using a 3.9 kernel in Ubuntu 12.04, it was the same situation, won't turn on during boot but can be switch on with Fn key.
I have checked the rfkill list, no device was blocked
So, how do I make my wifi automatically turn on with newer kernel? It will be more convenient for me~~
Ps:I'm using bcmwl-kernel-source
