Issues with broadcom 4313 wifi card on a samsung NP305

Tuxer · 2012-01-13 14:28:17

Hi
I'm currently having issues with getting the wifi to work on my broadcom 4313 wifi card on a Samsung NP305U1A. The command

lspci -vnn | grep 14e4

returns 14e4:4727, so according to the wiki, I chose the "brcmsmac" driver. I blacklisted correctly b43, bcma in the /etc/modprobe.d/modprobe.conf file, rebuilded the mkinitpcio image, so when I type lsmod now, the only wifi modules loaded in my kernel are :

brcmsmac 569864 0
mac80211 221981 1 brcmsmac
brcmutil 6912 1 brcmsmac
cfg80211 165796 2 brcmsmac, mac80211

I still don't see the wlan0 appearing when I type ifconfig though.
Would you have any advices?
Thank you very much,
Tuxer

What if you type

ifconfig -a

And if that doesn't help

dmesg

(and paste the output here)

I'm so stupid, the interface was down. Thanks

However, even after my ifconfig wlan0 up (that now displays wlan0 when I ifconfig), wicd doesn't show any wireless networks when I refresh

Do you see any APs when you scan manually using

iwlist wlan0 scan

Again, if there is any problem, paste the dmesg output here.

Tuxer · 2012-01-13 18:27:07

No, I don't see any APs, but I get absolutely no errors in the dmesg, it's weird.

Are you using the testing repo? I am also having issues with my 4313 related to testing/kmod replacing module-init-tools. When I revert back, to module-init-tools from core, all is well with my wireless again.

Thank you very very much for the tip!

I'm using [testing] and hadn't been able to get wifi to work again for several days.

Replacing kmod with module-init-tools and downgrading udev and mkinitcpio to the [core] versions did the trick for me.

Hi
I'm not using the [testing] repos at all, and I still have the same problem : even if wlan0 shows up on ifconfig, when I type iwlist scan, I get;

wlan0 Failed to read scan data : Resource temporarily unavailable

as an answer. Dmesg returns :

[ 70.774862] ADDRCONF(NETDEV_UP): wlan0: link is not ready

Thanks for any help you might provide :-'

Hi
I have a problem with a b4313 devise in a Notebook Samsung NP305 too.

The networkmanager list all APs, but It does not connect after input the network key. The same form, (without networkmanager)... "iwlist wlan0 scan" list all APs, but "iwconfig wlan0 essid <mynet> key <network_key>" no connect with Access Point.

The driver is "brcmsmac" and the system has blacklisted bcma module.

Any Idea???

Thanks

Hi !
I have the same problem with a samsung series 3 305u1a...
I tested also with windows 7 64 bits... and this the same ... Maybe a hardware problem ?

Hi!

I have a samsung Series 3 305U1A with the same problem.

The driver is "brcmsmac", blacklisted "bcma" module.

I tested also with Opensuse, Ubuntu, Fedora, Debian in their last version and I had the same problem.

Any idea?
Someone had the same samsung without this problem?

Sorry for my english, is a bit limited

Hi,
i have exactely the same problem as mjaimes. I tried all the drivers possible for the bcm4313 chip. I tried the wl, brcmsmac (with blacklisted modules) and the ndiswrapper windows driver. None of the driver is working. The main problem is that i cannot register with the access point. Sometimes after restart it can authenticate and i have a signal to the access point, but a VERY poor speed. Finally the connection drops again and i cannot get a connection no more. I tried to disable the bluetooth module, since it is coexisting on the same chip. I tried the 2.6.38 kernel the new 3.1 kernel -> no success. I tried in addition debian testing/ stable and ubuntu. All with the same result. The chip works on the preinstalled Windows 7 :-(. I don't know what to test next, maybe somebody else has a good idea.

Hi everybody!

I've found a solution for this problem (at LinLap, see pierre comment on Feb-24-2012) and it worked for my Linux Mint installation. On " /etc/modprobe.d/blacklist.conf" I didn't have the "blacklist b43" line, it was only on a previous comment line, but I commented the next line (it was similar) and added the same blacklist at end of file.

Uninstall the 'Broadcom Sta' driver
Open the file /etc/modprobe.d/blacklist.conf
Delete the line:
blacklist b43
Add these two lines at the end of the file:
blacklist bcma
blacklist brcmsmac
Save and exit
Type:
sudo apt-get remove –purge bcmwl-kernel-source
Reboot
Type:
sudo apt-get update
sudo apt-get install bcmwl-kernel-source
Reboot
Select the 'Broadcom Sta' driver

Best regards and I hope this works for you too

I had exactly the same problem as honio running xubuntu 11.10 (sorry for not using Arch yet). I tried the Covelus instructions and it seems to be better. The wireless now connects faster and it stays connected. It has done so for about 15 minutes now. But the speed is very bad. I only get 0.5 to 2 Mb/s (different from time to time) using www.bredbandskollen.se compared to 19-20 Mb/s when using wired connection. On Windows 7 the wireless the corresponding figures are 6Mb/s and 16Mb/s respectively. Isn't that bad too? I have tried to disconnect/connect the wireless, but with the same result. After rebooting the wireless connected fast but then started to disconnect and had problem to reconnect again, asking for WPA2 password several times.

I think I solved my problem. It was the Avahi daemon that disturbed the wifi. I disabled it by changing AVAHI_DAEMON_DETECT_LOCAL=1 to 0 in /etc/default/avahi-daemon and reboot. This also removed the anoying message "Network service discovered disabled" at login. Oh, and my wifi speed on W7 is now up to 12-13 Mb/s. I moved closer to the wireless router. The wifi speed on Linux (still xubuntu) is now 15-16Mb/s.

My samsung 305u1a not connect to the wireless network.
I did everything humanly possible.
Install the proprietary driver 'broadcom-wl "without success.
So I thought of buying a new wireless card.

One day, note that some lap-tops had no black cable connected, if only the white wire.

And I opened my notebook.

Remove the white wire and black, and it worked, detected and connected to the network.
After several tests, just let the white wire, and so far still working.

A little ironic, because linux-mint probe in its live DVD, and run my wireless card on another computer, but mine did not.

So I inquire me that within the laptop there is a short-circuit, now I'm writing from the wireless connection.
Obviously I'm using the open-sourse driver
