I'm trying to setup the WiFi connection on my Lenovo B590 but I get the following error :
ifdown: interface wlan0 not configured wpa_supplicant: /sbin/wpa_supplicant daemon failed to start run-parts: /etc/network/if-pre-up.d/wpasupplicant exited with return code 1 Internet Systems Consortium DHCP Client 4.2.2 Copyright 2004-2011 Internet Systems Consortium. All rights reserved. For info, please visit https://www.isc.org/software/dhcp/
Cannot find device "wlan0" Bind socket to interface: No such device Failed to bring up work-network
So I looked up which firmware I need so my Debian 7 Wheezy system could find wlan0.
NOTE: the wlan chipset is a Broadcom Corp. BCM43142 and its PCI-ID is 14e4:4365
host@user $ lspci -vnn -d 14e4: |grep Network
02:00.0 Network controller : Broadcom Corporation BCM43142 802.11b/g/n [14e4:4365] (rev 01)
I found this article on the Debian Wiki giving all the steps needed to get it working, I followed them and got no errors anywhere.
I set up the WiFi interface with wpa_supplicant but when I run
$ ifdown wlan0 $ ifup wlan0=work-network
I still get the error Cannot find device "wlan0" Bind socket to interface: No such device
Do you know what is missing for it to work?
EDIT: below is the
