See this first




I do. I see no problem with that.
While screenshots might be relevant to you, here is a description on what information you should provide (mentioned it already in the other topic you commented):

Not all wifi models work by default and in many cases the laptop model is also important as it might require custom kernel boot parameters. See some related broadcom-wl driver here:

Thank you for reply but my laptop is dell & when i use ubuntu or mx linux or knoppix there is already a wifi icon below & i just have to click it & select my router name & enter password & the internet works fine but in this os no Matter what i am doing it just dont show the wifi icon on taskbar

Is the problem occuring because i am using it on a live usb pen drive without installing?

Well, no worries. I know this inconvenient can be frustrating, but lets focus on the technical part. Make sure you provide this:

Then i can look if that model of wifi is or not one that requires manual intervention, then i could answer this

without speculating or going on the wrong track.
Regardless the issue, i'm sure is possible to fix it :slight_smile:

Thank you brother you know i was frustated

Wait i will give the information you asked.sorry if i insulted you unknowingly

Please read about how to use Android USB phone tethering to get a working internet connection to upload outputs. It is impossible to offer advice until you have provided your hardware specs.

Once you have provided the required information someone may be able to help you.



That is not helpful, you must upload outputs as text not pictures.


Disable MAC Address Randomization.

Enter this command in the terminal to automatically generate the required file:

echo -e "[device]\nwifi.scan-rand-mac-address=no" | sudo tee /etc/NetworkManager/conf.d/disable-random-mac.conf

After creating the new conf file, reboot both your router and your computer.

Install both of the newest kernels and test your wifi on different kernels. The newer kernels have been working better for some Broadcom adapters.

Enter these commands in the terminal to install the newest kernels:

sudo mhwd-kernel -i linux52
sudo mhwd-kernel -i linux53

Please post:

rfkill list all

Please follow my above advice to hopefully get your adapter working. You have a very problematic broadcom adapter that many have problems getting working with Manjaro. If my above advice does not fix things for you there is little that can be done for you.

ok brother i will follow your advise but for your information i am using this linux on a bootable usb pendrive as a live image as of now

[manjaro@manjaro ~]$ rfkill list all
0: hci0: Bluetooth
Soft blocked: no
Hard blocked: no
[manjaro@manjaro ~]$

Without installing there is little that can be done for you. The fix requires the newest kernels which cannot be installed in a live environment. Any change that requires a reboot such as kernel installs are wiped at a reboot. Changes are non-persistent in the live environment.

My recommendations will be of little use until you install.
