Unhappy Cant connect to wifi networks


I was using kali linux.. I couldnt connect to any wifi network.. After researching in many forums, I reinstalled kali linux. Even after that I couldnt connect to wifi. So i tried installing zorin os and ubuntu too. Still on both the OS i couldnt connect to wifi network.. Before installing kali linux i was able to coonect to wifi in Ubuntu..

I also tried using an USB Wifi adaptor TP-LInk TL-WN721N too.
Still i cant connect.

Please help..

Hi...

Welcome to the forum

We'll need information on your adapter before we can possibly help you with this. Please open a terminal and post the results of the following command (no screenshots, please)...

Code:
lspci -nnk | grep -i net -A2
If need be, we can look into your USB adapter later. Also, is this a laptop or desktop system? What is the brand and model (and model number) of it?

Regards...

Your English is fine, no problem. If you want to try Zorin, you should be able to install and/or activate the driver for your Broadcom adapter by going to "System Settings --> Hardware --> Additional Drivers" upon installation of the operating system.

If it's not in that location, look under "Synaptic --> Settings --> Repositories --> Additional Drivers." More information here.

I'm not sure how the driver would be installed in Kali, I would have to research that.

Regards...

I'm going to take a guess here but if you have an ethernet connection to your system and you've enabled networking in Kali, you can try using the following two commands in order, one at a time...

Code:
sudo apt-get update
Code:
sudo apt-get install bcmwl-kernel-source
There is more information here.

After it gets done installing, reboot your system. Let us know how it goes.

Regards...

These links may help too.

https://wiki.debian.org/brcm80211
http://askubuntu.com/questions/55868...reless-drivers
https://help.ubuntu.com/community/Wi...Driver/bcm43xx

Another thing is try to find the Linux driver for your Wifi adaptor TP-LInk TL-WN721N and install it.

If you want the usb WiFi Adaptor to work I think you will have to disable (in the BIOS) the on board wireless card.

Hi...

Also, if the above advice advice doesn't work, can you tell us what exactly happened in both OS's? What error messages did you receive, if applicable? Did you install Zorin to your hard drive? Please open a terminal and post the entire results of...

Code:
dmesg
This might give us a clue as to what's going on.

Regards...
