Installation
Since the Minimal Installation CD[1] does not come with the necessary firmware to use the wireless networking controller you will be forced to use another live system, if you are planning to establish a wireless lan connection during installation.
Kernel
Wireless
Since the Intel Corporation Wireless 7260 required additional firmware, it won't work with a kernel out of the box. The following steps will guide you how to built the necessary firmware into the kernel:
Note
It's also possible to load the firmware from the userspace.
It's also possible to load the firmware from the userspace.
Installing the firmware
When installing the firmware you can either choose the hardware specific package sys-firmware/iwl7260-ucode or the general package sys-kernel/linux-firmware.

KERNEL Adding wireless support
'"`UNIQ--pre-00000004-QINU`"'
TPM (and suspend/resume)
A common problem can be encountered if the TPM chip has been activated in UEFI/BIOS. If the kernel lacks the necessary drivers the system freezes when attempting to resume from a suspend.
