Cant access wifi

[jaimedr]

I am trying to access the wifi using kubuntu 24.04 with an HP All-in-One Computer Pavilion 23-q010 AMD A8-7410 4GB DDR3 1TB HDD 23. I can only access to the internet through the eternet cable, however I can not manage to activate the wifi, it worked well the wifi with windows.

Could you post the output of

lspci

?

[TinyTim]

while ethernet is plugged in look for "additional drivers" in software mgr. There may be a proprietary driver there.

[kc1di]

Need to know what wifi card/chipset is in that machine.in a terminal type lspci and post the results.

For this card, you will need to install a package that will build a kernel module for it, and update it with every kernel release as needed.

You might also need to disable Secure Boot if you are using it.

sudo apt install bcmwl-kernel-source​

[kc1di]

I would install "broadcom-sta-dkms

sudo apt install broadcom-sta-dkms

when finished reboot wifi should be working.
Also make sure that broadcom in not blacklist in

sudo lsmod

(Note: you will have to be connect via cable or via phone.

I already managed to have a wifi access point, however it is intermitent I get the following message: The access point /org/freedesktop/NetworkManager/AccessPoint/357 was not in the scan list.

how do I know broadcom is no in blacklist?

[kc1di]

how do I know broadcom is no in blacklist?

Go to /etc/modeprob.d look for a file broadcom. it will list any mod black listed if sta is listed edit the list with a text editor and delete the sta one.

[claydoh]

Dang, I forgetted that the old package name bcmwl-kernel-source now just installs broadcom-sta-dkms
I do not see any broadcom wifi driver being loaded, unless it is the wl.
Now, with the wifi actually able to be used and seeing SSIDs, we should check to see which driver is actually loaded.

$ sudo lshw -C network

Here is an example:
br

[sudo] password for banana:

I don't think any blacklisting is involved with this, now that the STA is the only (?) driver.

But some common issues with these can be not liking it if both a 5ghz and 2.4ghz SSID have the same name, not liking WPA3, and possibly just general wifi channel shenanigans. Maybe power savings in the driver being too aggressive, or it needs to be turned off in Network Manager for this card.


Edit /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf and changing the 3 to a 2

[connection]
wifi.powersave = 2

And reboot.


I haven't had Broadcom WiFi in many, many years, but I do know I ripped that sucker out and replaced it with an Intel card. Sometimes doing that is my first step, though that is usually with Realtek Wifi. But I know this is not always feasible, though it would not necessarily be very pricey depending on the type of card, and might even gain superior wifi support.

[kc1di]

WL is broadcom. and it is loading. Check the following command also

rfkill list

Post the results here.
