My laptop is HP 250 G4 P5T98ES

My OS is: Debian jessie 20160917

While I was installing Debian from live-usb, it told me that it can't connect to the wireless network because it has no non-free drivers. So I decided to install the driver later. I downloaded wireless driver from the debian site (in fact, I downloaded the whole pack of non-free firmware. Then I run the command in terminal in su mode:

dpkg -i firmware-brcm80211_0.43_all.deb

The output tells that it is installed successfully (or something like that). Then I ran:

dpkg -l firmware-brcm80211

And it gave me the following output:

Desired=Unknown/Install/Remove/Purge/Hold | Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend |/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad) ||/ Name Version Architecture Description +++-===============================-====================-====================-==================================================================== ii firmware-brcm80211 0.43 all Binary firmware for Broadcom 802.11 wireless cards

I have reboot the system but in the network settings I still see only two options: wired and network proxy.

After adding this line:

to /etc/apt/sources.list , apt-get update fails :

PROBLEM SOLVED by installing debian from live-cd version which has firmware included. Now I have my wi-fi.

    Your DNS is failing. See your error message, Could not resolve 'httpredir.debian.org'. You need to fix that before you can move on. Commented Sep 30, 2016 at 20:28
  • @roaima how can I fix that? Do I need wired connection to internet? Commented Oct 1, 2016 at 12:09

You are installing the wrong driver for your card.

You have BCM43142 802.11b/g/n [14e4:4365] which uses the wl module.

Read about this in the official Debian documentation.

Where you will find this information as to how to install the (correct) driver:

Add a "non-free" component to /etc/apt/sources.list for your Debian version, for example:

# Debian 8 "Jessie" deb http://httpredir.debian.org/debian/ jessie main contrib non-free

Update the list of available packages. Install the relevant/latest linux-image, linux-headers and broadcom-sta-dkms packages:

# apt-get update # apt-get install linux-image-$(uname -r|sed 's,[^-]*-[^-]*-,,') linux-headers-$(uname -r|sed 's,[^-]*-[^-]*-,,') broadcom-sta-dkms

This will also install the recommended wireless-tools package. DKMS will build the wl module for your system.

Unload conflicting modules:

# modprobe -r b44 b43 b43legacy ssb brcmsmac bcma

Load the wl module:

# modprobe wl

The BCM43142 wifi is buggy under the current kernel version 3.16 , you can read the comment of @Stephen Kitt about the Debian Bug report from here , i suggest to compile the 3.2.82 version then install your driver following the steps described here . Also you can install a new kernel from backports the 4.6 or the 4.7 version.

Edit

Follow this answer to fix your sources.list first .
