Wireless connection failing

Archlinux fresh installation.
Laptop: HP Compaq 6720s with Broadcom 4312 wireless adapter with proprietary driver:

$ lspci -vnn -d 14e4
lspci: -d: ':' expected
[archio@laportabile ~]$ lspci -vnn -d 14e4:
10:00.0 Network controller [0280]: Broadcom Corporation BCM4312 802.11b/g LP-PHY [14e4:4315] (rev 01)
	Subsystem: Hewlett-Packard Company BCM4312 802.11b/g Wireless LAN Controller [103c:137d]
	Flags: bus master, fast devsel, latency 0, IRQ 17
	Memory at e4000000 (64-bit, non-prefetchable) [size=16K]
	Capabilities: <access denied>
	Kernel driver in use: wl
$ lsmod | grep -i wl

cfg80211              433688  1 wl

Wired connection works fine.
I've a WPA2 wireless connection at home which I can't connect to.
Both wicd and network manager GUI fails on authentication.
Wireless networking has always worked fine in the past using "wl" driver.

I've tried:

$ sudo systemctl start dhcpcd@wlp16s0

Re: Wireless connection failing

Where are you putting in your WPA passphrase? Do you have wpa_supplicant running?  I think you need it to associate with an encrypted network.  Have you tried using wifi-menu from netcfg[1]? Alternatively, you could use netctl[2] from [testing] because it's going to take over for netcfg once it hits the stable repos.

Re: Wireless connection failing

I have the same card but I use b43 with b43-firmware.Works like a charm.

Re: Wireless connection failing

I have the same card you have on my Inspiron1525 and sometimes wpa_supplicant/netcfg give me some headaches, I don't know why.

My personal recommendation is that you use NetworManager and nm-applet along with the b43 driver, as PinkPanther  noted.

EDIT1: Also check that b43 and wl modules are not loaded at the same time, b43 module might be loaded automatically.

1) Put it in NetworkManager and wicd applet (obviously I don't use both at the same time)
2) How do I see if wpa_supplicant is running?

I've tried to connect manually to a non protected wifi but it's not doing anything:

b43 NEVER worked good to me, since I was Using Ubuntu 5 years ago. (this computer has seen Ubuntu, debian, openSUSE, debian, arch and none of them worked good with b43).
I'll try them again.

EDIT: Ok b43 installed and loaded by lsmod and still not working, it doesn't event try to connect, it flash for a millisecond and nothing more.
Do i have to extract b43 firmware with b43-fwcutter as explained here? http://linuxwireless.org/en/users/Drive … ed_devices
archwiki doesn't mention doing anything like it.
Does installing b43-fwcutter execute it?

EDIT 2: b43 up and running, but still can't connect. I've tried wpa_supplicant also.

$ sudo wpa_supplicant -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf

Re: Wireless connection failing

Yes, you do need the firmwares, but you can also get them from the b43-firmware AUR package. More info here https://wiki.archlinux.org/index.php/Br … Fb43legacy

Also, here is someone who had a simmilar problem and a simmilar log: https://bbs.archlinux.org/viewtopic.php?id=145756

And finally, if I were you, I'd run a live CD to rule out hardware issues last Ubuntu should work, since we now have libre drivers...

Up what?

What have you tried since your last post? What have you read since your last post?
Do the error messages give you any clues? (something about security maybe?)
How are you configuring NetworkManager?

Sorry but in the rules from a localized archforum there's no mention about bumping.

I've tried to connect to an open wifi (my smartphone's hotspot/tethering) without success.
I've tried to configure it manually with the same settings as my desktop, except for the IP which is +1.
Wouldn't be better to get rid of NM/wicd and just concentrate on very low level tools like wpa_supplicant?

Sure.  I use netctl.  There is a tool a came across last weekend with which I was most impressed -- for dealing with wpa_supplicant, wpa_gui is simply amazing.  wpa_cli also works, but is a lot more manual.

I guess the real question I had is not to which devices are you attaching, but rather what commands are you using to set up your system.


Edit:  Or, you might try wifi-menu.
Edit:  No worries over the bumping.  It is actually okay to create a post to bring life back to a thread iff (if and only if) there is more light brought to bear on the subject.  Like I said, just tell us what you learned, where you've looked, what you've tried.  Often, it helps us shake the cobwebs out.

Re: Wireless connection failing

I've already tried wpa_gui but it doesn't show any adapter or network, any idea?

Now I'm installing netctl, anyway isn't it just a tools-suite? I already have some of its components.

I'll try wifi-menu as well. Well I've forgotten that wifi-menu is provided by netcfg which I've wiped out in favor of netctl.

I have the same card but I use b43 with b43-firmware.Works like a charm.

I've decided to try with b43, so I've wiped wl driver.

- installed b43-firmware
- installed b43-fwcutter

At boot I get:

giu 25 01:29:02 laportabile kernel: b43-phy0: Broadcom 4312 WLAN found (core revision 15)

giu 25 01:29:02 laportabile kernel: Broadcom 43xx driver loaded [ Features: PMNLS ]

"pacman -Ql b43" shows that all files are correctly extracted in /usr/lib/firmware/b43, included ucode15.fw.
Permissions for /usr/lib/firmware/b43 are set at 755.

I don't get why it doesn't find the firmware at boot.
