My computer is Dell N5110 ,and my wireless card is Wireless-N 1030,sorry for my poor English :oops:

lspci -k|grep less
09:00.0 Network controller: Intel Corporation Centrino Wireless-N 1030 [Rainbow Peak] (rev 34)
        Subsystem: Intel Corporation Centrino Wireless-N 1030 BGN



After I update my kernel (from 3.16 to 3.19), I cant use my wireless

and this is my demsg info

Code:

dmesg |grep iwl

Get the firmware from somewhere, for example here https://packages.debian.org/jessie/firmware-iwlwifi

Are you sure he does not have the firmware? It is included in every version of linux-firmware I have here (both older and newer than the version OP used, although I skipped his version). Based on his kernel configuration, IWLWIFI is builtin. Based on the dmesg output, it initializes very early. I suspect that he does not have root mounted when it looks for the firmware. If so, then his problem is not that he does not have it, but rather that he does not have access to it when he needs it.

No, not sure. Since he mentioned it worked with older kernel I assumed it was built as module and the newer version of driver required newer version of firmware. Seemed logical looking at information given.

Newer Kernel try to load the Firmware before / is available, so you either build the FW into the Kernel or you build the driver as module. Booth will work as solution.

My personal preference is to build as much as possible as module and to emerge sys-kernel/linux-firmware before rebooting into the new kernel.
