These two separate specs correspond to two different versions of the Gigabyte X570S Aero G MoBo. You need to confirm which card your MoBo came with. Easiest would be to check the output of dmesg and 'lshw -short -class network' after you boot with Mint. If you run 'lshw -class network', you will additionally see what driver is loaded my Mint and what firmware files are needed. > > 2.

The MoBo manual is listing two different wireless NICs depending on the version of your MoBo: https://www.gigabyte.com/Motherboard/X570S-AERO-G-rev-1x/sp#sp If your wireless card is Intel, the kernel driver is iwlwifi. If your wireless card is MediaTek's MT7921K (rebranded by AMD) then your kernel driver is mt7921. You can confirm with lshw which of these is loaded when you boot with Mint, alternatively you can also note what firmware files are being used by the card: lsmod and modinfo <name of loaded module> [snip ...] firmware: .... firmware: .... Then when you boot with Gentoo, check in /lib/firmware the above listed firmware files are already there. > > 3.

For an exhaustive list of network options you could configure in /etc/conf.d/ net, you may want to explore the content of /usr/share/doc/netifrc-*/ net.example.bz2 > > Substitute wlan0 with whatever your wireless NIC is identified as > > in 'ip link show'. > > 'ip a' + 'ip link show' both list 3 interfaces : > (1) lo ; (2) enp6so (my landline) ; (3) sit0@NONE <noarp> mtu1480 ... . OK, this is because you the required wireless card driver is not installed/ loaded in your kernel and therefore the interface is not initialised by the kernel. > With SR + Mint, the interface is shown as 'wlp5s0' (see below), > which I've written in 'net' in place of 'wlan0' (3 times), > eg 'config_wlp5s0="dhcp"'. > > (The landline interface works correctly) > > > 4.

Once you configure and reboot your Gentoo kernel with the necessary wireless driver, it will pick up the card, load any corresponding firmware files, or complain in dmesg if these are missing, then start the wpa_supplicant and dhcpcd services to configure your network connection. It appears but for a missing kernel driver you're almost there. :-)
