[ SOPVED ] wifi adaptor not detecting

[sharp veldt]

i installed latest arch Linux today in my laptop, in my 500gb hdd
i have also windows in ssd

my wifi adaptor is not showing in arch , but showing in windows

[fluid ridge]

Have you finished the installation or are you trying to get internet to work in the terminal?

[sharp veldt]

installed arch Linux

[fluid ridge]

ok so you are on a desktop right now right?

[sharp veldt]

currently on phone

[fluid ridge]

No I mean in your arch installation

did you get a desktop environment installed

or did you stop at the terminal

[sharp veldt]

what do u mean?, i used my physical adaptor for internet to install arch

🤥

but my laptop have also a inbuilt adaptor, that is not detecting by arch

[fluid ridge]

I am trying to understand if you just installed arch and are sitting on a terminal trying to install a desktop environment package, or if you have gotten a desktop installed and can't see your dongle in the wifi settings

[sharp veldt]

last line

[fluid ridge]

so you have a desktop setup right?

[sharp veldt]

yes

[fluid ridge]

alright

I assume you were able to install arch linux with wifi from the command line so you'll most likely have to go back to the installer to install any required packages for your wifi dongle

Did you do a manual install or did you use archinstall

[sharp veldt]

arch install

[fluid ridge]

ok

are you able to get on your laptop right now? I need you to type this command pacman -Qi linux-firmware

[sharp veldt]

yes i can go

[fluid ridge]

it's a package that contains drivers for a lot of devices

[sharp veldt]

Qi , i tried Q by morning 😂😂

[fluid ridge]

there is a chance archinstall did not install it by default

[sharp veldt]

ok let me try

@fluid ridge

[fluid ridge]

?

[fluid ridge]

ok this means it is installed

[sharp veldt]

btw i haved plugined my physical adaptor

[fluid ridge]

you said neither the internal wifi nor the adaptor works right?

type pacman -Qi networkmanager

btw you don't need sudo for pacman -Q commands. -Q just reads information, it does not need permission to write stuff to the root

[sharp veldt]

ok

[fluid ridge]

systemctl status NetworkManager.service?

[sharp veldt]

ok

see without physical adaptor

[fluid ridge]

yup I see it

if you are able to plug in an ethernet cable, does the internet seem to work?

[fluid ridge]

check that out after doing this command

[fluid ridge]

ok that seems to be working fine as well then

[sharp veldt]

not cable

[fluid ridge]

Yeah I mean do you have any ethernet cables you can plug in or no?

Because that would help us round down the problem to wifi issues and not a network setup issue in general

[sharp veldt]

no i haven't any cable

[fluid ridge]

alright that's fine

can you try ip addr

[sharp veldt]

should i plugin the dongle?

[fluid ridge]

shouldn't need it right now

[sharp veldt]

ok

[fluid ridge]

Give me a minute. I am looking up stuff to find the problem

[sharp veldt]

what is this? lo

@fluid ridge

[fluid ridge]

not sure but I am pretty sure all arch devices have it. Shouldn't cause any issues

[sharp veldt]

ok

[fluid ridge]

yup I have it as well

[sharp veldt]

ohk

[fluid ridge]

wait I may have found the issue

one second

try sudo systemctl enable [e-mail]

[sharp veldt]

what is that?

[fluid ridge]

when you typed ip addr you can see all your network interfaces including your wifi interface

it says that it is disabled for some reason

this command should enable it on startup

[sharp veldt]

failed to enable unit

[fluid ridge]

hm

[sharp veldt]

service doesn't exit

?

[fluid ridge]

try pacman -Qi dhcpcd

[sharp veldt]

not found

[fluid ridge]

ok this means you need to install it which needs internet which needs you to go back to the installer usb and enable it from there

but before that

you may be able to enable your wifi adaptor without having to install dhcpcd

if you type ifconfig does anything show up?

[sharp veldt]

no

[fluid ridge]

ok then I think you need to go into the usb sadly

[sharp veldt]

can't install now? From terminal

[fluid ridge]

no because you don't have internet access

you need internet to install stuff

[sharp veldt]

ihave

[fluid ridge]

huh?

[sharp veldt]

i said i have physical wifi adaptor

[fluid ridge]

does it work?

[sharp veldt]

.

[fluid ridge]

you said it didn't work previously if I am not mistaken

[sharp veldt]

i installed arch install through this , bcoz my laptop inbuilt adaptor not showing

[sharp veldt]

no my physical adaptor works , in built adaptor is not detecting by arch

[fluid ridge]

oh

ok plug the adaptor in

connect to the wifi

[sharp veldt]

done

[fluid ridge]

and type ping www.google.com to make sure internet is working

[sharp veldt]

working

[fluid ridge]

ctrl+c to stop the ping command

then type pacman -Syu and pacman -S dhcpcd

[sharp veldt]

yeah i did this while installing arch 😂

[sharp veldt]

ok

[fluid ridge]

the first command will update your entire system

You should never do pacman -Sy if you haven't heard this already before

it can lead to your system breaking

always pacman -Syu for updating

the second command will hopefully install dhcpcd

[sharp veldt]

i did this by Morning😂

[fluid ridge]

which is a program that takes care of ip management

[fluid ridge]

yeah most times it won't break anything but it will eventually

[sharp veldt]

hm

done ✅

now?

[fluid ridge]

type ip addr again

[sharp veldt]

also enabled dhcpcd

[fluid ridge]

with the systemctl command I sent you before?

[sharp veldt]

yes

[fluid ridge]

ok

unplug the adaptor and reboot

and pray that this was the problem

[sharp veldt]

ok 😂

[fluid ridge]

I don't have too much experience with wifi, I use a desktop PC so not sure what else could be the issue otherwise sorry

[sharp veldt]

i have pc also 😂

[sharp veldt]

that's my pc's adaptor

[fluid ridge]

Ah alr

I only use ethernet

[sharp veldt]

still not showing

[fluid ridge]

ok

I have one last idea

give me a second

Can you tell me if this command outputs anything lspci | grep "Broadcom"

If your laptop has a broadcom network card you need to install a seperate package for it to work apparently

try this command as well lspci -vnn -d 14e4:

[sharp veldt]

ok

@fluid ridge

[fluid ridge]

ok that means you have broadcom that's good

try the second command as well

[sharp veldt]

ok

@fluid ridge

[fluid ridge]

plug in your wifi adaptor and install the broadcom-wl package using sudo pacman -S broadcom-wl

[sharp veldt]

done ✅

now?

[fluid ridge]

unplug the adaptor and reboot

[sharp veldt]

ok

thank thank thank

3000 times

[fluid ridge]

it worked?

[sharp veldt]

working

[fluid ridge]

nice!

[sharp veldt]

[sharp veldt]

again thx 🙏

The Bubble Package Manager received a thank you cookie!

Thank you

[sharp veldt]

one more

😂😂

[fluid ridge]

?

[sharp veldt]

how to remove this ubuntu

i have installed it by last week , but it's corrupt

ed

[fluid ridge]

did you replace ubuntu with arch or install alongside it?

[sharp veldt]

no

i format it while installing arch

[fluid ridge]

ok

[sharp veldt]

gdisk /dev/sdb

[fluid ridge]

which option is your arch installation?

[sharp veldt]

hard drive

[fluid ridge]

UEFI: Hard Drive? alright one sec let me look this up

[sharp veldt]

yes

[fluid ridge]

this can be pretty different depending on your UEFI firmware

try booting into the UEFI settings

or just select BIOS settings at the screen you are looking at

and send a screenshot

[sharp veldt]

ok

one more help , can it will become, after starting laptop it will show which you want to open arch or windows

bcoz every time i need to use f12

[fluid ridge]

you can set this up inside arch. I can show you after getting rid of the ubuntu option

I assume you use grub on arch right?

[sharp veldt]

yup

[fluid ridge]

alright then it should be pretty easy to make it show windows as well

let's get rid of the broken ubuntu option first though

[sharp veldt]

in UEFI there is ubuntu only

[sharp veldt]

ok

[fluid ridge]

that is a pretty weird uefi firmware not gonna lie

[fluid ridge]

Wait arch is not uefi?

[sharp veldt]

not showing in bios settings 🤥

[fluid ridge]

Do you use Interal HDD or UEFI: Hard Drive to boot into arch

[sharp veldt]

uefi hard drive

[fluid ridge]

hmm

try deselecting ubuntu and reboot?

[sharp veldt]

ok

[fluid ridge]

if it doesn't let you boot you can just come back and re enable it

[sharp veldt]

done

now ubuntu not showing in bios

[fluid ridge]

if you reboot does it load into arch?

[sharp veldt]

i mean in UEFI

[fluid ridge]

try launching arch

[sharp veldt]

hm

[sharp veldt]

ok

lauched

[fluid ridge]

ok

now let's get windows showing up

you need to install the os-prober package so type pacman -S os-prober

[sharp veldt]

done

[fluid ridge]

ok now do nano /etc/default/grub

[sharp veldt]

done

[fluid ridge]

You need to find a line like this #GRUB_DISABLE_OS_PROBER=false

you just need to remove the hashtag and save the file

so in the end it should look like this GRUB_DISABLE_OS_PROBER=false

if you press ctrl+w you can search for text btw

[sharp veldt]

hot it

[fluid ridge]

alright

ctrl+x to save and exit

when you are out type sudo grub-mkconfig -o /boot/grub/grub.cfg

and that should be it

you can reboot and see if windows shows up

[sharp veldt]

permission denied 🤥

[fluid ridge]

oh right

[sharp veldt]

sudo

[fluid ridge]

yup

exit without saving

and do the nano command again with sudo

change the same line and save

[fluid ridge]

probably gonna need sudo for this as well

[sharp veldt]

reboot?

[fluid ridge]

yup

[sharp veldt]

i hope that's my last reboot 😂

should i need to press f12?

[fluid ridge]

no

does arch not launch without entering the boot menu?

[sharp veldt]

windows is not listed there

[fluid ridge]

hm

launching windows from the boot menu does work right?

[sharp veldt]

lauched

[sharp veldt]

i didn't tried yet, but it's working

[fluid ridge]

you should try it again because you may have accidentally uninstalled windows

[sharp veldt]

btw windows is installed in ssd

[fluid ridge]

as far as I know os-prober should detect windows automatically

[sharp veldt]

wtf

[fluid ridge]

maybe you accidentally chose the wrong partition in archinstall?

I do not know

try launching it

[sharp veldt]

working windows

[fluid ridge]

ok

that's good then

[fluid ridge]

it's weird how os prober does not detect it

try going back into arch then

[sharp veldt]

arch is installed in hdd

windows is in ssd

[fluid ridge]

that shouldn't matter

[sharp veldt]

opened

[fluid ridge]

try installing the ntfs-3g

[sharp veldt]

ok

-S?

[fluid ridge]

yeah pacman -S

[sharp veldt]

done

[fluid ridge]

even if this doesn't work this gives you the ability to write in ntfs drives so you can move stuff from arch into windows if you ever need to do this

reboot

if windows doesn't show up just go straight into arch

[sharp veldt]

ok

[sharp veldt]

reboot?

[fluid ridge]

you did run mkconfig right?

[sharp veldt]

no

[fluid ridge]

yeah

[fluid ridge]

oh

that was the issue

[fluid ridge]

.

[sharp veldt]

should i?

[fluid ridge]

yes

[sharp veldt]

ok

[fluid ridge]

it will make a new config for grub

the one you edited was just a template

[sharp veldt]

done

[fluid ridge]

now restart

[sharp veldt]

noq reboot?

[fluid ridge]

yep

[sharp veldt]

ok

still

[fluid ridge]

hmm

idk

you can change this post's title and make it into grub os-prober not working or something

maybe someone more experienced can help you out

[sharp veldt]

leave

i will boot when i need windows

tyx for all stuffs

[fluid ridge]

np

[sharp veldt]
