Linux Lite Forums

I am a newbie to the world of Linux. I installed Linux Lite 7.6 on my old laptop Dell Latitude D830. During the installation, the wifi driver was recognized and installed, as well as my network. However, the wifi network won't connect. I checked the password several times and after 3 tried, it disconnected. Using inxi -N from the tutorial, I received the information below:
Device-1: Broadcom and subsidiaries NetXtreme BCM57755M Gigabit Ethernet PCI Express
driver: tg3
Device-2: Broadcom and subsidiaries BCM4311 802.11a/b/g
driver: b43-pci-bridge
Device-3: Dell Wireless 360 Bluetooth type: USB driver: btusb

The wifi was working in windows 7 before I wiped it to install Linux Lite 7.6. Any help to get the wifi working will greatly be appreciated it.

Welcome Tom
Debugging wifi issue over the forum can be frustrating but given your description we stand a good chance of getting it working.

Which tutorial did you follow ?

Please can you confirm my understanding of your description is correct, if incorrect, please provide more details.

1) While booted from the live media (before installation), the wifi was detected, connected to your network and worked.
2) During the installation, between setting the keyboard and choosing whether or not to apply updates, the wifi was detected, connected to your network and worked.
3) After installation completed, the wifi hardware can 'see' your network, but fails to establish a working connection.

Quote:I checked the password several times and after 3 tried, it disconnected.

Can you clarify what this means please ?

Once we have a mutual understanding I'll provide some commands to run.

Hello,
Please allow me to clarify.

My wifi was working when the computer was on Windows 7. I created the linux installation USB using Rufus and downloaded the ISO copy of Linux Lite 7.6. During the boot up to install Linux Lite, a dialog box asked me to pick my network from all the detected networks. I picked mine and it asked me for the password. I entered it and clicked Connect. I checked "Show Password" to make sure I entered it correctly. It took several minutes, then the dialog box asking for the network password came up again, the second time. I entered the password again (same one) and clicked connect. It took several minutes, then the dialog box asking for the network password came up again, the third time. I entered the password again and clicked connect again, then it took several minutes and a dialog box came up saying network disconnected. The installation continued and was successful.

After rebooted, Linux Lite came up, but no wifi. I tried to connect following the Linux Lite Help Manual (https://www.linuxliteos.com/manual/) to no avail.

To answer your questions
1) While booted from the live media (before installation), the wifi was detected, connected to your network and worked.
TNB: When I booted from the USB, I got option 1 to go to live media or option 2 to direct install. I chose option 2 to direct install.
2) During the installation, between setting the keyboard and choosing whether or not to apply updates, the wifi was detected, connected to your network and worked.
TNB: During installation, the wifi network was detected and asked for password (I entered the password, it tried, then it asked for the password again, then it tried, then it asked for the password again, then it disconnected), but it didn't connect to my network and it didn't work.
3) After installation completed, the wifi hardware can 'see' your network, but fails to establish a working connection.
TNB: After installation completed and rebooted, I saw my network, but it kept asking for password and after 3 tried, it said disconnected. I tried to connect to the network 3 times (entered and checked the password 9 times).

I found the command inxi -N via the tutorial and from searching the web. I also clicked on the Install Drivers GUI and it didn't show anything and it said something like no proprietary or third party drivers found.

Appreciate your help! Thank you!
Tom

Does your wifi password - the wpa authentication key - contain any characters that are not either numbers or letters ?

Test the typing by using a text editor.
Click 'Menu' and begin typing 'text editor' into the search box
When you see 'Text Editor' offered as a choice, click on it to open the Mousepad application.

Type your wifi password into the Mousepad window and carefully check that what appears on screen in the editor matches the key presses.
