wireless network adapter not connecting to any wifi network

hello! I have a problem. I have my wireless network adapter connected to my laptop but it doesn't connect to any wifi network. My laptop has wifi working but the signal is so weak (I think the wifi antenna is broken) so I always have to use my phone's mobile hotspot to connect to the internet and I have to put my phone so close to my laptop. But this isn't my problem. This is the reason why I'm using a wirless network adapter. I used windows 10 in this laptop but it was so slow so I switched to Manjaro XFCE and it performs well. When I was in Windows, I didn't have this problem that my wireless network adapter doesn't connect to any wifi network. It shows the wifi networks. Please help! Thank you.

Hello,

Just passed by to mention that your description is not providing any wireless model, no detail about your hardware, kernel.

Most of us do not start with the premise there is an hardware issue. The mentions like "works in Windows" might have a negative recoil effect ... This is how we consider starting a good help request:


Welcome to Manjaro! :slight_smile:

Also, sorry because I'm not really good in English and I didn't understand all the things said in that tutorials but I will try.

This is the info of my wireless network adapter:

Thank you!

You will have to follow this:


Still in english, but should be straight forward as is providing all the commands to run.

You may be able to get your internal Broadcom wifi adapter working simply by disabling MAC Address randomization. Looking at your outputs the internal adapter is working. Search the terms "disable MAC Address randomization" on the forum for directions.
