LiveCD - Trying to get Wifi on a Dell latitude D620

Post by SprinterDriver »

Hi.

I'm testing Mint on an laptop model "Dell Latitude D620". This time I go with Mint 17.3, Mate 64bit.

I quickly discovered that Wifi wasn't available (now on cable). So I followed the instructions on this site
https://drndivoje.wordpress.com/2011/07 ... x-mint-11/

But no luck - here is partial output from Terminal - the restart procedure:

Code: Select all

mint@mint ~ $ sudo vim /etc/modprobe.d/blacklist.conf
sudo: vim: command not found
mint@mint ~ $ sudo pluma /etc/modprobe.d/blacklist.conf
mint@mint ~ $ sudo modprobe -r b43 ssb
modprobe: FATAL: Module ssb is in use.
mint@mint ~ $ sudo modprobe b43
mint@mint ~ $ 
So according to web site, I should be able to click at network symbol in system tray, and there should be a list of available wireless networks. But no, instead nothing changes:

So I got this bright idea. But when I tried to grab the light bulb, I did not hurt my hands as expected from a warm bulb, because it turned out to be one of those LED bulbs.

Firstly, we need to find out your exact wireless chip. Please use this terminal command, and copy/paste the complete output back here in a reply.

inxi -Nx

PS: That link is for Mint 11 . . a long ways away from Mint 17. Bad idea to use it imho.

Here is the Terminal text output:

Thanks Pjotr, I'll try that.

However - When I have to find a cable every time I want to do a live session on that laptop, the question emerges: Is it possible to make myself a custom Live-CD (ISO-image) where that particular driver is bundled? Alternatively - is there any way to install that driver by having a file on a memory stick and install it without internet access?

Dell Broadcom BRCM94311 DW-1390 WiFi Adapter Driver Install

I have 4 Dell laptops running Linux Mint 18.2 Sonya 64-bit, 2 of them have Broadcom wifi adapters and 2 have IntelPRO/Wireless adapters.
I hope this helps anyone using a Broadcom WiFi adapter.

The Broadcom drivers must be downloaded for the WiFi adapter to work. But, that's not possible until you have an internet connection. Follow Step A or B below. (Step A preferred, but either will work).

A. Install via USB WiFi Adapter:
1. Connect to internet with a USB WiFi adapter.
2. Go to Menu/Adminsitration/Driver Manager.
3. Choose this driver for WiFi to work:
firmware-b43-installer
Version 1:019-2
firmware installer for the b43 driver
NOTE: Do NOT choose the "recommended" driver; it did NOT work (for me).
4. Click "Apply Changes".
5. Click "Restart" when finished.
6. Unplug USB WiFi adapter when Linux shutsdown, before restart.
7. Click on WiFi icon on taskbar.
8. Select your WiFi "SSID name".
9. Enter password.
10. Click "OK".

B. Install via Terminal:
1. Connect to internet with a USB WiFi adapter.
2. sudo apt-get install firmware-b43-installer
3. Follow prompts.

WiFi_LAN Info:
Open Terminal and type:
inxi -Nx

Results:
Network: Card-1: Broadcom BCM4311 802.11b/g WLAN
driver: b43-pci-bridge bus-ID: 05:00.0
Card-2: Broadcom BCM4401-B0 100Base-TX
driver: b44 v: 2.0 bus-ID: 08:00.0
