No internet on Broadcom BCM4352

[Gurannsan]

When i try to connect to internet it just tries for a while and then asks for the wifi password again.

Edit: Can’t post anymore if you see this I will be editing my last one

[Halcek]

Check your keyboard layout/caps lock if you are not mistyping the password unconsciously (a case of Xy problem) ?

Did it previously work?

What desktop environment are you using?

[ricklinux]

Hello @Gurannsan
Could you show the output of lspci -nn -d 14e4:

[Gurannsan]

I have tried to retype it several times. I haven’t really gotten it to work on linux a lot at all, but a long time ago i managed to do it on Ubuntu downloading some Broadcom drivers. So far i havent found any drivers that work here. Think i use xfce or something.

04:00.0 Network controller [0280]: Broadcom Inc. and subsidiaries BCM4352 802.11ac Wireless Network Adapter [14e4:43b1] (rev 03)
this is the output of lspci -nn -d 14e4:

[ricklinux]

Are you using the broadcom-wl-dkms module?

[Gurannsan]

I tried to install it earlier but i got errors trying to activate it

[ricklinux]

Are you sure it’s errors or it’s trying to remove what is there and replace,. This is the module you should be using for that chip.

[ricklinux]

sudo pacman -S broadcom-wl-dkms

[Gurannsan]

it says that i need to run “rmmod b43 b43legacy bcm43xx bcma brcm80211 brcmfmac brcmsmac ssb wl
modprobe wl” to activate it and then i get that there is unloaded modules;

rmmod: ERROR: Module b43 is not currently loaded
rmmod: ERROR: Module b43legacy is not currently loaded
rmmod: ERROR: Module bcm43xx is not currently loaded
rmmod: ERROR: Module bcma is not currently loaded
rmmod: ERROR: Module brcm80211 is not currently loaded
rmmod: ERROR: Module brcmfmac is not currently loaded

rmmod: ERROR: Module modprobe is not currently loaded
rmmod: ERROR: could not remove ‘wl’: Operation not permitted
rmmod: ERROR: could not remove module wl: Operation not permitted

i tried to reboot it earlier but it still didn’t work

[ricklinux]

Did you try the above command?

[Gurannsan]

yeah i did that first, and in the command it said that i needed to run the command i posted just now to activate it, then i got the errors from that command.

"To load the new module, run the following commands as root:

rmmod b43 b43legacy bcm43xx bcma brcm80211 brcmfmac brcmsmac ssb wl
modprobe wl

Or just reboot the system."

i tried both things here

[ricklinux]

What does lsmod show?

[Gurannsan]

this is the result of sudo pacman -R broadcom-wl;
[sudo] password for gurannsan:
error: target not found: broadcom-wl
[gurannsan@DesktopEnOS ~]$

Can’t post anymore today so i will just edit the old ones

@ricklinux

@Gurannsan

“rmmod b43 b43legacy bcm43xx bcma brcm80211 brcmfmac brcmsmac ssb wl

modprobe wl” to activate

Did you run this as root?

No i did it with normal user but i tried now with the same results

@ricklinux

@Gurannsan

rmmod b43 b43legacy bcm43xx bcma brcm80211 brcmfmac brcmsmac ssb wl

modprobe wl” to activate

sudo pacman -S broadcom-wl-dkms linux-headers

Then run the commands as root to remove what it say’s.

What commands?

If its these;
"Try sudo pacman -R broadcom-wl

Then try to install the dkms version.

sudo pacman -S broacom-wl-dkms"
Then it still didn’t work

@Halcek

Try these steps:

1. Install yaourt -S broadcom-wl-dkms
2. Unload modules with:

rmmod b43
rmmod ssb
rmmod bcma

Load these modules:

modprobe -r wl
modprobe wl

"sudo pacman yaourt -S broadcom-wl-dkms
[sudo] password for gurannsan:
error: target not found: yaourt

[gurannsan@DesktopEnOS ~]$ modprobe wl
modprobe: ERROR: could not insert ‘wl’: Operation not permitted
[gurannsan@DesktopEnOS ~]$ sudo modprobe wl
[gurannsan@DesktopEnOS ~]$ "

Still doesn’t connect

@Halcek

Add the following to /etc/modules if you don’t have it there yet:

lib80211
lib80211_crypt_tkip
wl

I don’t know what you mean. I’m quite new to this. sorry

@Halcek

My mistake. Do yay -S broadcom-wl-dkms instead…

Still doesn’t work
modprobe commands worked this time but not connecting to internet

@Halcek

@Halcek

Add the following to /etc/modules if you don’t have it there yet:

lib80211

lib80211_crypt_tkip
wl

This should be done with sudo nano /etc/modules . After pasting these, press CTRL+O, then CTRL+X .

You may have to reboot afterwards…

Still no connection.

@ricklinux

Show rfkill list all

1: hci0: Bluetooth
Soft blocked: no
Hard blocked: no
2: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no

@Halcek

After installing broadcom-wl or broadcom-wl-dkms, remember to install linux-headers package too.

“sudo pacman -S linux-headers
warning: linux-headers-5.5.13.arch1-1 is up to date – reinstalling
resolving dependencies…”

and then it just reinstalled it

@ricklinux

@Gurannsan
I guess you should try creating a blacklist file.

sudo nano /etc/modprobe.d/blacklist.conf

Put the following inside.

blacklist b43
blacklist b43legacy
blacklist bcm43xx
blacklist bcma
blacklist brcm80211
blacklist brcmfmac
blacklist brcmsmac
blacklist ssb

Then ctrl o enter to save
Then ctrl x to exit.

Edit: Then reboot and see

still nothing

thx for all the help btw. really apreciate it.

@ricklinux

@Gurannsan

You can use the following command and see if it is using any module.

lspci -nnk | grep -iA2 net

It shows this;

[root@DesktopEnOS gurannsan]# lspci -nnk | grep -iA2 net

[root@DesktopEnOS gurannsan]#

The link you sendt said something about appending this kernel parameter; b43.allhwsupport=1
i have no idea on how to do that but it might work.

@ricklinux

Also are you currently connected via network? If you click on the network icon it doesn’t show any wireless.

i am not connected to any wireless network no

I tried to connect to personal hotspot from my phone and it connected just fine, so there is probably someting wrong with the router. I will try to restart it, because that’s like litteraly everything i know that might help.
didn’t work. I will continue to search around, and if you find something then it would be great.

@ricklinux

Other than that I’m out of ideas. Sorry.

Thanks for the help anyways.

@Halcek

What is the output of pacman -Q broadcom-wl currently for you?

[gurannsan@DesktopEnOS ~]$ pacman -Q broadcom-wl
error: package 'broadcom-wl' was not found

I can share my mobile data and connect to that through WiFi, so there might be something wrong with the router settings?

[ricklinux]

@Gurannsan

wl 6467584 0

Try sudo pacman -R broadcom-wl

Then try to install the dkms version.

sudo pacman -S broacom-wl-dkms

[ricklinux]

@Gurannsan

“rmmod b43 b43legacy bcm43xx bcma brcm80211 brcmfmac brcmsmac ssb wl

Did you run this as root?

[ricklinux]

@Gurannsan

rmmod b43 b43legacy bcm43xx bcma brcm80211 brcmfmac brcmsmac ssb wl
modprobe wl” to activate

sudo pacman -S broadcom-wl-dkms linux-headers

Then run the commands as root to remove what it say’s.

[Halcek]

Try these steps:

1. Install yay -S broadcom-wl-dkms
2. Unload modules with:

rmmod b43
rmmod ssb
rmmod bcma

Load these modules:

modprobe -r wl
modprobe wl

Add the following to /etc/modules if you don’t have it there yet:

lib80211
lib80211_crypt_tkip

[Halcek]

@Halcek

Install yay -S broadcom-wl-dkms
