| 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. |
