Ubuntu Networking :: Broadcom Bcm4306 Won't Find/connect To Wireless Networks?
Oct 16, 2010
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 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:

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've been running Karmic since it was officially released on my Dell Studio 17 (specs are in my signature) with a Broadcom wireless half mini wireless card.hen I installed Karmic, it gave me the option to install proprietary drivers for my video card as well as 2 Broadcom drivers, STA and one of the BC43 drivers. I installed all of these, and the only problems I had were with the audio. I spent a few days troubleshooting the audio and finally got PulseAudio set up for my card.
Almost 3 months later, I was making use of my wireless network at home, as I had done plenty of times over the previous 3 months, when I closed the lid (thus putting the computer into sleep mode) and took it to the hospital to stay with my fiancé¥ after her surgery. When I got to the hospital, I couldn't get their network to show up. Network Manager didn't even recognize the network. We had also brought my fianc饧s laptop (same machine with a slightly less powerful CPU and only 4 GB of RAM). She is running Windows 7, which detected the hospital's network with no problems.After trying to ad-hoc the hospital network with no success, I finally just gave up and played Sudoku and toyed with some graphics stuff in GIMP until we came home. Upon returning home, however, I was shocked that my card didn't even detect our home network.
I have been unsuccessful for the past 3 days in getting Network Manager to identify our wireless network. The wired network connects without issue and I am able to make use of a USB Belkin adapter, which identifies all 7 of the various wireless networks in my neighborhood, including our home network.While I would be able to simply carry my Belkin adapter with me in order to make use of wireless networks, I would really like to solve this problem with my Broadcom adapter. I've gone through the Ubuntu Wireless Network Troubleshooting guide, but I still can't get it to workOutput of lshw -C network:

I'm running Puppy Linux from a SD card on a netbook and there wasn't any drivers for the wireless adapter so I went online and found a module for my Broadcom B4312. The module is already installed and when I go to check for available networks I'm able to see my network and a neighbour's network. The problem: I can't connect to my network, which has a WPA2 Passphrase protection. Theoretically this driver won't allow Puppy to link with WPA2 protected networks so I changed the protection to a WEP one and even like this it won't connect.

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 made the mistake of creating a new user account and deleting the old one in Ubuntu. Now I can't connect to my wireless network. I think that I have the correct drivers installed, but I am unable to see (discover?) wireless networks and don't even have any wireless options in the upper right corner. I am pretty frustrated with this.
Laptop: Dell Inspiron 1721
Ubuntu 11.04
Network Controller: Broadcom BCM4311 802.11b/g WLAN
How do I set up the ability to see wireless networks?
Is there a way to verify that I have the correct network device drivers installed?

For some reason, ubuntu cannot find local wireless networks. In fact, the Broadcom wireless card Ralink RT5390 802.11b/g/n seems to be incompatible with ubuntu. I've tried numerous 'solutions' on the Internet, but none of them seem to work on my computer. Tutorials I've visited have recommended downloading the b43 drivers from the Synaptic package manager and also the bcmwl-kernal-source package. Nevertheless, the wireless never turns on and Additional Drivers never shows anything at all. After several exasperating hours of trying to get my wireless running I've decided to turn to the forum for help. I'm sure there's probably more information I should supply, but I'm honestly not sure what that would be.

I went out and purchased a Sabrent PCI wireless 802.11n card with the RT2860 chipset because it was on the ubunutu compatibility list and has linux driver available from the manufacturer. I was impressed that the card worked in wireless G mode out of the box, which is a great start....
However, I can't find any wireless N networks. Dual booting I can find/use my N network, but in ubuntu I can only find my G network. This is somewhat frustrating because I bought this card and a new (read: expensive) Linksys E3000 router specifically to run a nice new N network...
I have downloaded, made, and installed (reboot) the latest driver from the manufacturer, but it still won't find any N networks. I found a few posts by searching here and google that alluded to changing this line: "HT_OpMode=1" (from 0 to 1) in the config file RT2860STA.dat located in /etc/Wireless/RT2860STA/ and a reboot. It didn't work for me.
Frankly all this rebooting is starting to **** me off ... I have spent most of last night trying to setup my 180$ wireless network and its still no better than the freebie DDWRT54g based wifi it replaced. I am frustrated, perhaps someone wiser in the ways of ubuntu and wireless N can shed some light on the situation....
I forgot to mention I am on Karmic Kola, amd64 with the standard gnome.

I have a machine running Xubuntu [2.6.22-14-generic]. I have been trying to get this machine connected to wireless for ages, and I'm having another stab at it. So far I have install ndiswrapper and loaded the driver for a Linksys wireless adapter. The output of 'ndiswrapper -l' reports:
Code:
wusb11v4 : driver installed
devoce (13B1: 000B) present
So as far as my newbie knowledge goes, I believe that step to be completed, correct?When I turn on the machine is type in
Code:
sudo sh
modprobe ndiswrapper
to get the card running to where it will appear in the iwconfig dialog.The commands 'iwlist wlan0 scan' will list all the wireless networks around me, but I have been un-able to connect to any network, even unencrypted ones. I have tried to connect both through Wicd and command-line to no avail. For command-line I have used:
Code:
sudo ifconfig wlan0 down
sudo dhclient -r wlan0
sudo ifconfig wlan0 up
[code]....
With the final 'dhclient wlan0' commands, the following is returned:
Code:
There is already a pid file /var/run/dhclient.pid with pid 134519120
Internet Systems Consortium DHCP Client V3.0.5
Copyright 2004-2006 Internet Systems Consortium
[code].....
I have attempted to go ahead a step further and connect to an encrypted wireless network, however, I receive the same message, as well as another error message upon trying to enter the key, with the following code:
Code:
iwconfig wlan0 key s:"thekey"
Error for wireless request "Set Encode" (8B2A) : SET failed on device wlan0 ; Invalid argument.

I have an Atheros AR242x card. It can see my wireless network (WPA2). When i attempt to connect to the network it asks for the WPA2 passphrase. After entering the password it begins connecting but hangs up for about 3 minutes before saying wireless disconnected. The wireless worked for one day on a fresh install (Ubuntu 10.04)and then started doing this.

I have a WLAN Driver Azure Wave AW-NU222 Wireless LAN Card in my Medion computer.
After installing Ubuntu it seems to detect the wireless networks in my area. However, when I try to connect to my network, it tries for several minutes and then times out with no error message. I have set up the credentials and also tried removing the encryption (WPA-PSK) from the network itself, but it still doesn't connect.
Connect via an Ethernet cable is fine, and I know that the network is good because I can connect via my Windows Laptop and various other wireless devices.
I suspect it's due to drivers, but I'm having trouble downloading a driver which I can try and install using Ndiswrapper. The Medion website just a windows executable when I try and download the driver specific to my machine when I really need the .inf file.

Here is a situation I have never come across (though I have only been using linux since 2004).I am running ubuntu 10.04 and using Wicd Network Manager.I can connect to my WPA encrypted home network, but if I go to my coffee shop to use their unencrypted wifi - I cannot.Even using the terminal. I think it is the way the device sees the network - but I don't know how to fix it.I have a screenshot with wicd here:And one with connecting to the essid here:Afterwhich, dhclient was unable to obtain an ipaddress - just like wicd above.
My iphone connected to this network easily without encryption or needing to use the browser to authenticate, etc.Any ideas on how to fix this?Specs:Samsung NC10lspci:

So I was the one who couldn't get their ethernet port to function properly. Most likely, this was the result of bad hardware since none of the community's suggestions for software fixes did anything. I believe this is probably true.Indeed, when I bought a cheap $10 wireless USB dongle, it immediately worked better than all the previous things. It detected networks, displayed network strength and even allowed me to attempt login.
The only problem now seems to be that it cannot login. I've rechecked the password countless times, but it just shows the 'connecting to wireless' animation for a minute or two and then poops out and says, 'disconnected'.I assume if everything is getting me this far, the driver is not the problem with the device. Is this a safe assumption?

I'm new to Ubuntu. Today, I took my old Compaq Presario V3010US and gave it life with Ubuntu 10.04. The hard drive was erased and replaced with the Linux OS stuff. Ubuntu recognizes most of the hardware except my Broadcom wireless card. I find this to be a pain because i'm a newbie to linux stuff. Anyway, can anyone help me fix this? I thank you for your time reading this.

I've installed it no problems on my desktop and I really love it. Now I'm trying to install it on my Satellite and I'm having a couple of problems. When trying to connect to my wireless network, I can see my network, but it will just keep asking me for my WEP. I've confirmed that there is nothing wrong with the network or the password I've provided. Sometimes when I boot up, the network manager just says that the wireless networks are disconnected and can't find any. The wired connection always works just fine.
Here are the system specs:
Toshiba Satellite M45 S169
Ubuntu 10.04 Lucid Lynx LTS Fresh Install
Ethernet controller: Atheros Communications Inc. AR2413 802.11bg NIC (rev 01)
Kernel driver in use: ath5k

so my wireless isn't working. My netbook wireless detects the available networks but when I try to connect it doesn't. The box that asks me to put in the password occasionally shows up but it still doesn't load. I even tried re-installing Ubuntu and didn't fix anything.I'm using kernel version 2.6.35-22-generic and

New Ubuntu user here, and I'm having difficulties connecting to my router at home. I've searched around the forum for a couple of hours now, to no avail. My router was originally not broadcasting ssid, so I turned broadcasting on. Now I can see the router, but when I enter a password (which I know is correct) nothing gets connected.

Basically, I just installed Fedora in my desktop (use it on my laptop), and have a big problem, which is that Fedora (13), detects my wireless card (Edimax nMAX EW-7728IN), but when I try to connect to my wireless networks (WEP & WPA) it hangs and asks again for the password. I know the problem isn't from my routers,since I'm right now connected via Fedora 13 in my laptop.

I just installed 9.10 and I can't detect any wireless networks. Is the card compatible with 9.10? Do I need to install any drivers? If the card isn't compatible with 9.10 is it compatible with later versions of Ubuntu? Marking this as somewhat urgent as I need to get internet access for some coursework soon, and also because my parents will kill me if they find out I've done anything unusual with the laptop because it's new and they think anything non -MS is a virus.

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.
