It seems you have the correct module for the mediatek driver installed, since lshw on gentoo shows it being used. What is not shown is the firmware. Do you see now the wireless link when you run 'ip link show', or is it still absent? The 'rfkill list' command (from sys-apps/util-linux) will list if by mistake you have left your wireless adapter switched off - laptops have a hardware button on the keyboard for this; e.g. ~ # rfkill list 0: phy0: Wireless LAN Soft blocked: no Hard blocked: yes If so, press the keyboard button to unblock it. Now, to bottom out the firmware issue. You need to specify the firmware path in your kernel, as explained here. By default this would be under /lib/ firmware: https://wiki.gentoo.org/wiki/Linux_firmware Hopefully, the requisite firmware file blobs will be present in the latest stable 'sys-kernel/linux-firmware' package once you install it. dmesg will reveal if these are/not being loaded. For example, this is what I get on an old laptop with Intel wireless: [ 13.276068] Loading firmware: iwlwifi-5000-5.ucode [ 13.519131] iwlwifi :04:00.0: loaded firmware version 8.83.5.1 build 33692 5000-5.ucode op_mode iwldvm [ 13.622473] iwlwifi :04:00.0: CONFIG_IWLWIFI_DEBUG disabled [ 13.622483] iwlwifi :04:00.0: CONFIG_IWLWIFI_DEBUGFS disabled [ 13.622486] iwlwifi :04:00.0: CONFIG_IWLWIFI_DEVICE_TRACING disabled [ 13.622489] iwlwifi :04:00.0: Detected Intel(R) WiFi Link 5100 AGN, REV=0x54 [ 13.664327] ieee80211 phy0: Selected rate control algorithm 'iwl-agn-rs' [ 13.730477] iwlwifi :04:00.0 wlp4s0: renamed from wlan0 What do you do if the latest linux-firmware package does not have the firmware blob(s) your wireless card requires, because it is rather new hardware? Well, you could keyword the trunk version hoping it contains what you need: ** *l^bstd [compress-xz compress-zstd initramfs +redistributable savedconfig unknown-license] ["initramfs? ( redistributable ) ?? ( compress-xz compress-zstd )"] Or, you could compare what firmware files are loaded in Mint/SR ISOs and copy these over to your Gentoo system for now, or you could fish around the mediatek website for appropriate firmware files. Finally, set up a symlink from '/etc.init.d/net.wlp5s0' to '/etc/init.d/ net.lo', (or whatever your card is detected as if not wlp5s0) - see here: https://wiki.gentoo.org/wiki/Handbook:AMD64/Networking/Introduction and bring up your wireless network service: rc-service -v net.wlp5s0 start NOTE: Besides wpa_supplicant, other packages required like 'net-misc/netifrc', 'net-misc/dhcpcd' should be installed, if they have not been brought in as dependencies already. Please post back your dmesg and any terminal output if you are still having problems bringing up this wireless interface. PS. I saw this page which may or may not be still relevant with the latest stable kernels, but you may want to take a look either way: https://wiki.gentoo.org/wiki/User:Chess/MT7921e signature.asc Description: This is a digitally signed message part.

That's interesting, but it doesn't take me much further (smile). Yes, this is in the early stage of installing in a new machine. Wifi works easily with System Rescue + Mint (running from USB stick). The minimal installer -- presumably you mean Stage 3 -- didn't include 'wpa_supplicant' & I emerged it later. Your experience suggests there mb some pkg missing, which I need. Do you -- or anyone else -- have any idea what it might be ? Perhaps there's still some firmware missing, but I'm having difficulty identifying what it could be or where I would find it. Any more substantial advice is very welcome. -- ,, SUPPORT ___//___, Philip Webb ELECTRIC /] [] [] [] [] []| Cities Centre, University of Toronto TRANSIT`-O--O---' purslowatchassdotutorontodotca

Re: [gentoo-user] using Wifi in a new machine
are you installing gentoo or is this on a running system? because the minimal installer only uses wpa_supplicant i couldn’t get wi-fi to work when i was installing gentoo. once i had everything installed though it worked.

Driver here is mt7921e (first letter M) If it's not a copy/paste error, is it wrong in some config file? 'lsmod' gives the same result on both systems, incl firmware.

Re: [gentoo-user] using Wifi in a new machine
Thanks to Michael for his helpful advice. I've narrowed the problem down somewhat, but Wifi still doesn't work on Gentoo, tho' it does on Mint + SR. The difference seems to be that when I enter 'lshw -class network' in Mint, I get "network | description : Wireless interface ... ", but in Gentoo it says "network | description : Network controller ... ". Also, under "configuration:", Mint says "broadcast=yes, driver=nt7921e, driver_version=5.15.0-generic, firmware=__91-20220209 150915, latency=0, multicast=yes, wireless=IEEE 802.11", whereas Gentoo says only "driver=mt7921e, latency=0". 'lsmod' gives the same result on both systems, incl firmware. It looks as if modules + firmware are all installed, but for some reason Gentoo isn't recognising the device as Wifi.
