Subject: How to get wifi working (SOLVED)
« on: March 02, 2015, 12:32:52 pm »
Just installed Peppermint 5 on a Dell Latitude D360 laptop. I don't know how to get my wifi working. After reading on the forum here I found a little about this. I tried in a terminal  lspci -nn -d 14e4: /lib/firmware/. This is part of what came up regarding wireless:

NETWORK CONTROLLER: BROADCOM CORP. BCM 4311 802.11 b/g WLAN (rev 01)
SUBSYSTEM: DELL WIRELESS 1390 WLAN MINI-CARD
KERNEL DRIVER IN USE :b43-pci-bridge

I'm guessing I need to install b43 drivers. I can access internet on my Linux Mint installation on the same hard drive. Can anyone help me as to how to install the correct driver and get my wifi working in Peppermint?

Thanks in advance for any help.

Whilst connected to your router via an ethernet cable, try running:
Code: [Select]
sudo apt-get install firmware-b43-installer
then see if wireless works (possibly after a reboot)

If not, can you post the output from:
Code: [Select]
lspci -vnn | grep -i net
and
Code: [Select]
sudo lshw -C network
and
Code: [Select]
sudo iwlist scan
and
Code: [Select]
rfkill list

I should have mentioned in my first post my internet access is wireless only. Also my laptop's a Latitude D630, not 360.

Any way did the commands in a terminal you asked for:

douglas@douglas-Latitude-D630 ~ $ lspci -vnn | grep -i net
0c:00.0 Network controller [0280]: Broadcom Corporation BCM4311 802.11b/g WLAN [14e4:4311] (rev 01)
douglas@douglas-Latitude-D630 ~ $ sudo lshw -C network
[sudo] password for douglas:
  *-network               
       description: Network controller
       product: BCM4311 802.11b/g WLAN
       vendor: Broadcom Corporation
       physical id: 0
       bus info: pci@0000:0c:00.0
       version: 01
       width: 32 bits
       clock: 33MHz
       capabilities: pm msi pciexpress bus_master cap_list
       configuration: driver=b43-pci-bridge latency=0
       resources: irq:17 memory:f1ffc000-f1ffffff
douglas@douglas-Latitude-D630 ~ $ sudo iwlist scan
lo        Interface doesn't support scanning.

douglas@douglas-Latitude-D630 ~ $ rfkill list
0: dell-wifi: Wireless LAN
   Soft blocked: no
   Hard blocked: no
douglas@douglas-Latitude-D630 ~ $

I have Linux Mint on another partition with internet access. I could download and then transfer files from Mint to Peppermint and if I can install from there.
Also during boot up there's a message about downloading the correct firmware for wireless. The message goes by so fast I have a hard time reading the whole thing.

Thanks again.

OK an offline install is going to be harder .. what's the output from:
Code: [Select]
uname -a

Create a folder on your Peppermint 5 32bit  desktop called offline_firmware-b43-installer

download theses 2 files on another PC (or in Mint):
http://cz.archive.ubuntu.com/ubuntu/pool/main/b/b43-fwcutter/b43-fwcutter_018-2_i386.deb
and
http://www.lwfinger.com/b43-firmware/broadcom-wl-5.100.138.tar.bz2
and place them in the folder you just created on your desktop called offline_firmware-b43-installer

now open a terminal and run these commands in sequence:
Code: [Select]
cd /lib/firmware
then
Code: [Select]
if test -d b43; then echo "Deleting old b43 firmware directory...";  sudo rm -rf b43; fi
(if prompted, enter your password then hit enter again)
then
Code: [Select]
cd ~/Desktop/offline_firmware-b43-installer
then
Code: [Select]
sudo dpkg -i b43-fwcutter_018-2_i386.deb
then
Code: [Select]
tar xvjf broadcom-wl-5.100.138.tar.bz2
then
Code: [Select]
cd ~/Desktop/offline_firmware-b43-installer/broadcom-wl-5.100.138/linux
then
Code: [Select]
sudo b43-fwcutter -w /lib/firmware wl_apsta.o
then
Code: [Select]
sudo chmod 755 /lib/firmware/b43
then REBOOT

Now check if wireless is working ?

Worked like a charm!  :D Thanks so much for the help. I keep wondering how you all remember all those commands to run in a terminal. Again, thanks.

I have an AcerOne that had the same problem after I installed Peppermint 5.  I followed the instructions but my results did not work and it shows SOFT BLOCKED:  NO and HARD BLOCKED:  YES  after the "rf kill list" command line.  I rebooted and still no Wi Fi option.
