Perhaps a fresh inxi -F might help to confirm you’ve got the latest versions of compatible kernel + drivers installed?

maybe maybe lets seeeee

i tried to connect to my phone by making the phone a mobile hotspot, when i ran ip a it didnt detect the phone’s hotspot, is that normal, do i need drivers for this type of connection too? cuz ill mostly be using my phone for internet in the next days.

Other than the fact that you’re running xfce and I’m running KDE Plasma, both our kernels and wifi drivers are identical - so I don’t suspect there’s a compatibility issue with what’s installed.

As for why yours is DORMANT I cannot immediately figure. Trying to research further, perhaps a systemctl related issue.

RE: Phone as wifi … no, the problem is your wifi adapter isn’t “UP” and running, so whether the wifi signal is coming from your home wireless router or your phone send the signal, your Dell laptop can’t receive the signal. That’s why your ethernet hardwire connection is the only connection you’ve got right now.

yeh, tbh i aint knowledgeable enough to do much anymore at this point, ima wait for the others to login to the forum, maybe they know how to deal with this.

Well, that’s a better plan than anything I can think up at this point! Sorry I couldn’t get you to the finish line. I think you’re closer … but more expertise will be required. Best wishes.

Thanks for keeping with me up to this point, and sorry for bothering, have a nice day.

At first a side note. You had installed the “RT”-kernel. RT stands for “real time”. And these rt-kernel should be used only when its needed. For example for special audio tasks or for PLCs.
I suggest to run a non-rt kernel on a normal used pc.

Please change to the normal kernel first before we go futher.

Please read up on Broadcom wireless

U see my kernel is weird, the reason i didnt do a system upgrade in long time is because i couldnt do it before, whenever i tried to, it would tell me that there are no updates, thats because, on my last system upgrade before the one of yesterday, the laptop turned off during the upgrade, when i tried to turn it back on, an error showed up saying it cannot find the linuz boot, which lead to me having to run the system update by booting into a manjaro on a USB.
maybe this info would be useful to u guys

first rerun the update again:
sudo pacman-mirrors --fasttrack 5 && sudo pacman -Syyu
if there are no errors, post output from:
mhwd-kernel -li
pacman -Qs 'wl|broadcom|dkms|headers'

the first command didnt output any errors:

[djamel@djamel ~]$ 

install the headers for the 5.19rt kernel:
pamac install linux519-rt-headers
reboot and test wifi

nothing changed much, its detecting the device but there is not drop down on the SIDD option, also the ip a command still shows state DORMANT

lets try to reinstall it, so first remove it:

pamac remove linux519-rt-broadcom-wl linux515-broadcom-wl linux510-broadcom-wl linux510-broadcom-wl

reboot and switch to the 5,15 kernel, then uninstall the rt one:
pamac remove linux519-rt-headers linux519-rt
and provide output from:
inxi -N

how do i switch to the kernel 515 tho?

dont you have grub menu shown during boot?
open this file:
sudo nano /etc/default/grub
and edit this line to look like this:
GRUB_TIMEOUT_STYLE=menu
save it with: ctrl+x
update grub:
sudo update-grub
reboot and in the grub menu/advanced options select the 5.15 - not the fallback one, the normal one

thank you

here is the output of the command inxi -N

[djamel@djamel ~]$ inxi -N
Network:
  Device-1: Realtek RTL810xE PCI Express Fast Ethernet driver: r8169
  Device-2: Broadcom BCM43142 802.11b/g/n driver: bcma-pci-bridge

do keep in mind that i did not reboot before executing this command, i only rebooted to switch to kernel 515 and then i removed the linux519 header and then i executed inxi -N
