I have an Acer Aspire 1513LMi and I'm using Ndiswrapper 1.7 to run BCM4306 on a kernel compiled for AMD64.
I were able after some time to activate the WLAN and all worked fine, but I wanted to improve the configuration automatically loading the ndiswrapper module. So I added it in the list of the modules to be loaded at boot time and this caused a kernel panic " Kernel panic - not syncing: Aiee, killing interrupt handler!"

After that I remove the automatic loading of ndiswrapper module and I was able to power up  my PC again, but this time my wlan wasn't able to detect the WLAN at my home.
I also tried powering off and on the AP but it wasn't detected the same.
What did it change in my configuration that now I'm not able to find the WLAN ?

Thanks for your support,
