[SOLVED] Can't Connect to WLAN with BCM43228

tony5429 · 2014-03-14 02:38:36

Hi. I just got an Acer Aspire V5-171-6860 and everything works great except WiFi. This is the WLAN chip I've got...

[karam@yuri ~]$ lspci -vnn | grep 802.11
03:00.0 Network controller [0280]: Broadcom Corporation BCM43228 802.11a/b/g/n [14e4:4359]

According to the links on the wiki, brcmsmac and b43 don't support BCM43228 so I have tried using broadcom-wl and broadcom-wl-dkms. However, in each case, after installing and rebooting, I am unable to see any wireless networks. Per the wiki, I have also checked for b43 and ssb with lsmod (neither is running), and have tried blacklisting cfg80211 (also to no avail).

If it's helpful, I'm using wicd, and here's the output of ip addr:

[karam@yuri ~]$ ip addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default 
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo

2: enp4s0f0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000

    inet6 fe80::ba88:e3ff:fe4f:38cf/64 scope link 
       valid_lft forever preferred_lft forever
3: wlp3s0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000
    link/ether 08:ed:b9:f9:bc:f9 brd ff:ff:ff:ff:ff:ff

Any ideas? Thanks in advance!

I have this card and it works fine for me with the broadcom-wl package. Is your system up to date? Does the version of linux-headers match the version of the linux package? How are you trying to connect to the network?

Edit: BTW, all the necessary blacklisting is included in the braodcom-wl package. It gets installed as /usr/lib/modprobe.d/broadcom-wl.conf. I'm not sure about the DKMS package, as I have tried using DKMS for a few things and have never been too big of a fan of it.

Very odd... The system is now up-to-date, I installed your broadcom-wl version 5, restarted, and still am unable to see any networks (in WICD)...

[karam@yuri ~]$ pacman -Q linux
linux 3.13.6-1
[karam@yuri ~]$ pacman -Q linux-headers
linux-headers 3.13.6-1
[karam@yuri ~]$ pacman -Q broadcom-wl5
broadcom-wl5 5.100.82.112-13.1

For what it's worth, ip addr still returns the text shown in the first post.

Additionally, as far as I can tell, the module is loading fine....

[karam@yuri ~]$ lsmod | grep wl
wl                   2558772  0 
lib80211                3821  2 wl,lib80211_crypt_tkip
cfg80211              408199  1 wl

What about if you just use the basic tools directly? Try scanning with iw:

# iw wlp3s0 scan

tony5429 · 2014-03-14 10:43:14

So at first, when I ran this, it just told me that the network was down (-100). So I ran "ifconfig wlp3s0 up", and then ran "iw wlp3s0 scan" and it showed me all the networks perfectly. However, WICD still showed nothing. So then I restarted the computer, and found that wlp3s0 was "down" again.... Any ideas?

From the first post wlp3s0 was listed by `ip addr` - so this is not a driver issue. The interface is created and working.

The issue is simply connecting with wicd. If you want to stick with wicd, you should refocus your searches there - in other words, this is a wicd problem, not a broadcom problem. This can be further confirmed by following the manual connection steps in the wireless wiki. Unfortunately I can't help with wicd - it never was reliable for me (though it was some time ago that I last tried to use it).

tony5429 · 2014-03-15 13:37:16

Ha, silly me. I forgot that since I installed WICD before installing the wifi driver, I would need to update the WICD settings to use the wlp3s0 interface. Problem solved. Thanks, all!
