[EN] Cannot connect to wifi using BCM43142

[jjjrrr3]

I can see the available wireless networks but not connect.  network-manager asks for the password over and over again but never connects. Ceni runs but has no effect. It seems that I am not receiving any DHCPOFFERS, but I do not know what that means.

It took me a long time and many Web pages to get this far.  I could not even detect the wireless until the instructions that I found from the Dubious Disc. Maybe there is more configuration that needs to be done, but I am frustrated and do not know where to look next. Any suggestions or ideas?

My wireless chip set:

Hello jjjrrr3,

i got this info from the #debian-next channel on irc.oftc.net:

The Broadcom BCM43142 is a hybrid 802.11n and Bluetooth 4.0 device.  Its wireless LAN component (PCI ID 14e4:4365, incorrectly identified as BCM4365 by Broadcom's proprietary driver) is currently only supported by Broadcom's proprietary driver since version 6.30.223.126 (packaged in Debian testing as broadcom-sta, version 6.30.223.141-1 available in debian unstable/non-free).

Broadcom's proprietary wireless LAN driver (wl, aka broadcom-sta) supports devices based on the BCM4312 LP-PHY and BCM4313/4321/4322/43224/43225/43227/43228 chips.  To install (amd64 and i386 only), see http://wiki.debian.org/wl .  Since Debian 7 "Wheezy", this driver creates wireless interfaces with the 'wlan' prefix (see NEWS.Debian.gz).  Most chips are also supported by the open source b43 and brcmsmac drivers.


I think besides the unstable repo the instructions for wheezy will work also for debian unstable:

1) add "contrib non-free" to your debian source and "apt-get update".
2) install broadcom-sta-dkms
3) modprobe -r b44 b43 b43legacy ssb brcmsmac
4) modprobe wl

you can do step 2) by "apt-get installbroadcom-sta-dkms"     with an ethernetcable
or even offline with downloading from https://packages.debian.org/sid/all/broadcom-sta-dkms
and dpkg -i broadcom-sta-dkms_6.30.223.141-1_all.deb  ; continue with step 3) and 4) 

I hope this will work out for you as i don't own such device. Feel free to ask more.

greetings

you are just great in Support!

Thank you, Musca.  Your response was faster than mine, but I have the same problem after following the four-step instructions.  I'll try out the instructions on the wiki too sometime this weekend.
