如何在运行带内核4.2的Debian Jessie的Dell Inspiron 5559上解决WiFi问题。

以前，我们必须部署自定义内核4.2才能使声卡正常工作。

如何解决Debian Jessie问题

对于自定义+4.2内核，请检查此页面https://wireless.wiki.kernel.org/en/users/Drivers/iwlwifi并下载适当的无线驱动程序。

# wget https://wireless.wiki.kernel.org/_media/en/users/drivers/iwlwifi-3160-ucode-15.227938.0.tgz
# tar xf iwlwifi-3160-ucode-15.227938.0.tgz
# cd iwlwifi-3160-ucode-15.227938.0
# cp iwlwifi-3160-15.ucode /lib/firmware/

重新加载模块：

# modprobe -r iwlwifi ; modprobe iwlwifi

WiFi应该可以正常工作了。
