The current stable version is: sys-kernel/linux-firmware-20230515 I suggest you run an update to fetch this version - see below. > > dmesg will reveal if these are/not being loaded. > > 'dmesg | grep firmware' shows 10 identical lines : > > Loading firmware : mediatek/WIFI_MT7921_patch_mcu_1_2_hdr.bin : > failed with error-2 .

Hmm ... Mint seems to be using an older version, which according to this post has since been patched: https://lore.kernel.org/lkml/3198471.FQF0JACdhR@ripper/ > > or you could fish around the Mediatek website for approp firmware files. > > no sign of firmware files. OK. I had a look in the latest stable version sys-kernel/linux-firmware-20230515 for the file you reported an error on: $ find /lib/firmware -iname WIFI_MT7961_patch_mcu_1_2_hdr.bin /lib/firmware/mediatek/WIFI_MT7961_patch_mcu_1_2_hdr.bin $ ls -la /lib/firmware/mediatek/WIFI_MT7961_patch_mcu_1_2_hdr.bin -rw-r--r-- 1 root root 92192 May 18 16:16 /lib/firmware/mediatek/ WIFI_MT7961_patch_mcu_1_2_hdr.bin Do you get the same result?

This is merely to bring up the interface and establish your wireless network service at boot time, if you add it to the default run level: rc-update add net.wlp5s0 default but until you get it working, you can use this service to start/stop your wireless connection manually. > > https://wiki.gentoo.org/wiki/Handbook:AMD64/Networking/Introduction > > > > and bring up your wireless network service: > > 'rc-service -v net.wlp5s0 start' > > it gives "ERROR : fails to start".

Not yet, let's see if the missing firmware file is available in your /lib/ firmware first.
