Ubuntu Networking :: No AP In NetworkManager With Broadcom BCM4306 (B43)?
Apr 24, 2010
I have problems with my Broadcom BCM4306 (rev 03) on my HP nx6110ng Karmic.NetworkManager does not list any AP, even if there should be some. It did work for some days without problems, but suddenly stopped working. I made a kernel update with the update manager, but I am not sure if this caused the probem (I also used the wired connection, so I don't exaclty know when wireless stopped working). Reinstalling fwcutter wasn't successful. So I tried as suggested in https://help.ubuntu.com/community/Wi...oadcom_BCM4306 and added the following lines to /etc/rc.local
modprobe -r b43 b44 ssb
modprobe ieee80211_crypt_tkip
modprobe b44

I am new to Ubuntu and have just installed Ubuntu 10.04 on a Dell D600. My wired network is working perfectly however, my wireless card is unable to detect wireless networks. I am using a Broadcom Corporation BCM4306 wireless card. I have updated the drivers and it is installed correctly as far as I can tell. My card seems to be working, but it doesn't detect any wireless networks. I know that my wireless is functioning, because I can log on successfully with a windows laptop. In addition there are 5 or 6 other networks available, so it should be able to detect something. I am new, so please let me know what information you need and, if possible, how to find it.
Here is the results of "lshw -C network" from the terminal below:
mikee@mikee-laptop:~$ lshw -C network

I've been trying to troubleshoot this myself for the past couple of days, but to no avail so I have come in search of help.
I have a PCI wireless card, it's a Broadcom device using the BCM4306 chipset. I'm running the b43 drivers which were installed using fwcutter.
At my last place the card worked perfectly. There it was connected to an unencrypted network. I've recently moved places and it just refuses to connect to the new network here. The router is set up with a 64-bit WEP key. In Ubuntu, network manager sees the access point and prompts my to enter the password but will not connect, instead continually asking for the login. I have tried using wicd instead of network manager, and that just throws up a "bad password" error.
Signal strength to the access point isn't great, around 50% usually, however the same card connects and works perfectly when I'm booted into Windows Vista. Unfortunately I can't do anything to change the router's configuration and using a cable is not possible.

The Hardware Driversscreen shows that it needs the driver for it and when I click "activate" it tries to download it. This doesn't work because neither my ethernet nor wireless cards work.

i'm running ubuntu 10.04. i've followed these instructions:[URL]that got the light for the wireless on my laptop to light up but it doesn't seem to be able to find any networks.when i click on "connect to hidden wireless network" and enter the details + encryption code. it spends a few minutes trying to connect before asking for my encryption code again but i know that the code i entered is right.i'm using a belkin router with wpa/wpa2 encryption. but i think it's a problem with the wireless on my laptop rather than a problem with my specific network because under windows on other machines in my house i can see some of my Neighbours networks

I recently installed Ubuntu 10.04 (and eventually upgraded to 10.10) on a 6+ year old Gateway Laptop. When I booted Ubuntu up after installing it, I was rather surprised to discover that the wireless card didn't work. I am almost certain that the wireless card is a Broadcom BCM4306, but I am unable to determine what revision it is, if at all. When I look at the network connections widget, it says that the wireless card is not ready, and iwconfig (I think) says that it's disabled.
It's not a problem with the laptop itself, because I was able to get a Linksys usb wireless adapter to work just fine on it, although it was SLOW (about 90 kbs). I am trying to fix this on a FRESH installation of Xubuntu 10.04 with the default packages on it, nothing more. Now, I was able to get the wireless working ONCE on ubuntu, using fwcutter I think, but it went away upon reboot. One last thing, I am running the 32 bit Xubuntu 10.04 on what I think is a 64 bit machine (I think it ran x64 Ubuntu 10.04 before I ditched it), so how to figure out if it is 64 bit.

I was wondering if any of you knew of any linux distro that supported the bcm4306 wireless adapter, or one you could get it working on easily. I have tried Ubuntu, on a 6+year old laptop, which had the afore mentioned wireless adapter, and Ubuntu wouldn't get that miserable piece of hardware to work . I don't really care which distro of linux I put on there, as long as I can get the wireless adapter to work, and it isn't a pain to set up and use. I do hope someone knows of a distro that supports it. If you do know a fix for the wireless card in Ubuntu/Xubuntu, please post it on my other thread, which you should find easily in the wireless and networking section.

P.S. I am so sorry about the poor spelling in the title of the thread, I didn't notice the typos until I hit "post"

I tried using b43-fwcutter in accordance with the Ubuntu Forums and nothing happened, and then I decided to look a little further. According to LinuxWireless.org, the BCM4306/2 actually uses the b43legacy drivers, so I purged all of b43-fwcutter along with firmware-b43-installer and downloaded firmware-b43legacy-installer.
$ sudo apt-get install b43-fwcutter firmware-b43legacy-installer
Nothing happened, so I downloaded b43legacy manually per the instructions listed at LinuxWireless.com, and manually extracted from wl_apsta-3.130.20.0.o to my /lib/firmware folder. Nothing happened again. I made sure to check additional drivers and nothing shows up.
As per the ticket posting instructions, I've included all the info you guys could need. from what I can conclude, the wireless isn't even ON, but it's integrated and I have NO IDEA what I have to do to get it up and running.
At least in OpenSuSE 11.3 LXDE I was able to get the wireless on, although I had some major connection issues, I guess it couldn't resolve the handshake completely, or take my SSID/PSK properly.
Here goes! (God bless 2>&1 | tee -a)

I'm using version 10.04 of Ubuntu and for some reason, when I install a copy of Ubuntu or Ubuntu Server, I get a 'NetworkManager is not running' message in the notification bar where the network icon should be.What could be causing this? This is happening as soon as I finish installing the OS and I've not changed anything at all.I've been wrestling with this for weeks, trying different commands and trying different ways of setting up the OS to begin with, scouring the internet for answers, but nothing

I've set-up a Linksys WPC54G v5 wireless card using ndiswrapper and the appropriate Marvell driver. It seems to work ok. On my other laptop running Kubuntu with built-in wireless the routing all works fine - I just get prompted by Network Manager for the WPA passphrase and I'm away. However, when I try to connect to my wireless router on thix Xubuntu-based laptop I get really odd security options.
When I try to connect I get a security prompt asking me for a bewildering array of information. There are four basic authentication options under "WPA & WPA2 Enterprise": TLS, LEAP, Tunnelled TLS and Protected EAP. None of those offers a simple passphrase, they all have some combination of username & password with certificates and keys. If I try to connect to other networks in my area, some do just ask for a WPA passphrase, not that I know them to check!

Using kubuntu 10.04, I accidentally disabled networkmanager on startup for one of the users of my system. This user now has to manually start networkmanager each time after logging in. How can I make kde run networkmanager automatically again?How this happened: when I started a parallel session as an other user, while already connected via networkmanager in my own profile, kde detected this and asked something along the lines of "There's already a networkmanager running, run networkmanager automatically in the future?" Since I was a little confused, I clicked "no", and that's how things are ever since. I thought there would be some system setting that would allow me to restore this setting, but I haven't found it yet...

Is there a way of wireless networking without using the Gnome NetworkManager Applet? I want to connect to the Internet using a USB 3G modem and connect to wifi without knowing all of the details of every network.Network manager is pretty good but there seems to be no way of using it without starting an X session and it doesn't play nice with any other networking tool and reminds me too much of a Microsoft application.

I installed 10.10 and ran it for a few weeks and then (foolishly) installed Wicd and tried it and it failed. So I had no network connection. Can I re-install NetworkManager from the 10.10 CD? Or is there something else I can try in order to restore wifi access?

The resolv.conf is not written correctly every time i reboot the machine...it seems to ignore all sysconfig configurations !
this is the resoult resolv.conf after every reboot

I'm running ubuntu 9.10 with the latest networkmanager (from ppa)I thought this could be wrong credentials setting, so i've tried a huge amount of setups (user: phonenumber, password: phonenumber, avp:telenor, seems to be the general consensus for how it should be)Is there something I'm missing or is there any way I could tail the output as NetworkManager tries to connect (hopefully seeing something like "wrong password" etc.)

When I start a Kubuntu session, KNetworkManager requires that I type my password to the Wallet before it has permission to connect to the internet. How can I automatically give it permission without entering my password every time?

What I currently do is run this script -
Code:
rfcomm release 0
CHANNEL = `sdptool search --bdaddr=00:21:FE:A5:C9:4A dun | grep Channel | cut -c14`
rfcomm bind 0 00:21:FE:A5:C9:4A ${CHANNEL}
wvdial e71bt
And my /etc/wvdial.conf is configured for AT&T connection here in the US.
Question is, is there anyway I can integrate it with NetworkManager, instead of having to run this script?
There's a "Broadband" option on NetworkManager, but I am not able to get it to recognize my cell phone as a modem. The bluetooth applet only allows for file transfer

Is there any easy way to replace the default Gnome NetworkManager used by Ubuntu with Mandriva Net-Applet? Although I prefer Ubuntu, overall, I have had better luck with video streaming, browser speed, and consistency when using Mandriva (with iPV6 disabled).

I have a tenda W311u wireless with a ra3070sta chipset, i read a lot of tutorials to get it working. I recently had my wireless working but just in NetworkManager. I need to get working in console mode, for example when i make a:
Note: The Essid the same i added in the RT2870sta.dat file.
And therefore if i try a dhclient3 ra0 no dhcp offers received.
Rare, but if i start NetworkManager connected to azcor, and i make a dhclient3 ra0 i get an ip very fast.
I try with cnetworkmanager but is complicated and isnt working for me!

I got it set up in the NetworkManager applet (imported the client.ovpn), but when I connect it sends ALL my traffic through the VPN. I would prefer all accesses to the internet go over my normal default gateway, rather then all the way through to the VPN's default gateway.When I connect through the command line:
Code:
openvpn --config client.ovpn
I don't have this problem, and accesses to the internet still go over my default gateway on

I have no problems seeing the networks available and connecting to a network in KDE. But there is no network manager in GNOME. I might have messed up with the settings earlier. What I can do though is run knetwork manager every time I start up (or add it to start up programs). But that opens up the KDE wallet which would rather avoid.I am thinking I need to install something related to NetowrkManager.

if the NetworkManager uses wpa_supplicant? I normally dont use NetworkManager and decided to try it. I started it and tried it out and it works with WEP and WPA! I cant figure out why using the iwconfig command is not working by itself for WEP. WPA working with NetworkManager is just a bonus though.

I'm an inordinate amount of trouble getting F15 to run without NetworkManager. If I boot with the NetworkManager service enabled, my NIC presents as expected at /dev/eth0 (I'm using biosdevname=0). However, when I stop the NetworkManager service, /dev/eth0 disappears from the filesystem.If I boot without NetworkManager enabled, /dev/eth0 is never created. Reviewing dmesg, udev is loading an ethernet driver.

I'm using CentOS 5.4. I want to set-up a PPTP connection (I'm the client). I installed the NM pptp plugin from EPEL's repository. I have configured my PPTP connection in the NetworkManager applet but now I don't know how to connect to the server, I mean, there's nothing like 'Connect now'.

My networking seems to be OK but when any changes are made the NetworkManager Applet 0.7.996 (I think) in the panel pops up a small window ~ 300*80 pixels which displays some faint coloured lines and dotted lines where, presumably, there should be a message of some form. How can I configure it to get the message?

set the number of retries networkmanager attempts to connect to a network to infinity?
I live in an area of Australia were wired internet dare not tread (or so say the ISPs). My only real choice is 3G wireless broadband, and even that is iffy at times. Often late at night the network towers do "something" (reset, maintenance, etc. - no idea) and the internet drops out, networkmanager tries to reconnect, fails, tries again, (etc. etc.) until it ultimately gives up, requiring human intervention when the towers are done with whatever it is they are doing. This happens frequently, and I'd like to have networkmanager keep trying "forever" until it connects so I don't have to restart the connection each morning.
Where would such a thing be set? How does networkmanager know when to give up?

i have added a vpn connection on my Lucid desktop machine, but every time i try and connect, it fails. I also have the same, identical vpn connection on my karmic install on my laptop. everything works perfectly on Karmic, but Lucid is having problems. I have followed identical steps for creating the vpn connection on both machines: vpn connections can be made in 2 ways, the first is through the network manager, but trying to connect through the nm-applet returns an error about vpn failing to connect and "no valid vpn secrets".
I suspect this is at the root of the problem. The only way for my Lucid machine to successfully connect through the command line is if I run the openvpn command under sudo.
