Ubuntu Networking :: Broadcom 4318 Will Not Connect To Router
Feb 28, 2010
Ok, so spec's on my setup: Ubuntu 9.10 on a Dell Inspiron 530.. Q6600 w/3GB RAM, 500 GB HD w/radion 2600xt and broadcom wlan NIC. My issue is that the broadcom will not connect to my router. I did some searching, found a link from this site detailing how to get my NIC to work on Intrepid, but that's not what I have. I followed that guide anyway, substituting my driver for his (guide is on sampbar.com) and nothing. It's showing now as not ready. I've installed ndiswrapper and grabbed the drivers for my NIC from my Vista install, but when I use ndiswrapper to do that, I get an error saying it can't tell if the hardware is present, then shows me it is present and it still won't connect.

Here is what I have as far as hardware goes:
Compaq Presario V2000
- PROCESSOR: Intel Pentium M 710 -- 1.4 GHz
- RAM 2 GB
- HD 80 GIG
- Duel booting XP Pro with Ultimate Edition 2.8 (I understand this is built from Ubuntu 10.10)
- lspci -vnn | grep 14e4 yields the following:
Code:
03:00.0 Network controller: Broadcom Corporation BCM4318 [AirForce One 54g] 802.11g Wireless LAN Controller (rev 02)
I have followed to the tee this guidance: [URL]
I tried the installing b43 drivers with internet (using ethernet)
I tried installing off the DVD using the no internet option
I even tried installing the STA drivers even though I know the 4318 chipset is not mentioned as a supported chipset.
All of these were loaded/extracted with no errors via terminal following the guidance to the letter. Now here is a problem I have not read that anyone else has run into. (maybe I just missed it). When I go: System > Administration > Additional Drivers the only additional driver that shows up is "Software Modem". I can't for the life of me figure out why the b43 and STA drivers are not showing up to activate. I can install drivers all day long, if I can't activate them, it really does become a moot point.

I've got the b43 driver and firmware installed, and the system comes up fine, but the max throughput on the wlan0 is about 100Kb/s. My laptop and iwl do about 2.5Mbps from the same location in the house. The signal is plenty strong:
wlan0
IEEE 802.11bg ESSID:"sar2"
Mode: Managed Frequency:2.422 GHz Access Point: 00:23:69:22:5C:00
Bit Rate=36 Mb/s Tx-Power=20 dBm
Retry min limit:7 RTS thr:off Fragment thr:off
Power Management:off
Link Quality=61/70 Signal level=-49 dBm Noise level=-57 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0
Is this expected from the b43 driver and a bcm4318? I was hoping for much better throughput. Also, I tried the broadcom-wl driver, but it doesn't seem to recognize the card. It looks like it's not supported from their site, only the 4311,12,21,22 were listed, although I see posts where other people claim they are using it with a 4318?

I have a desktop PC running Ubuntu 9.10 and Windows 7, and a Eee PC 701 laptop running EasyPeasy Ubuntu 9.04. I'd like to connect the desktop to the laptop with a wired connection (eth0), then the laptop to my ADSL router using wireless (ath0).
I have a crossover ethernet cable (I bought on ebay). I have set up my laptop with a static IP address on my LAN and it uses OpenDNS.
I have added this to /etc/sysctl.conf on the laptop:
net.ipv4.ip_forward=1
Then I tried this on the laptop:
sudo iptables --table nat --append POSTROUTING --out-interface ath0 -j MASQUERADE
sudo iptables --append FORWARD --in-interface eth0 -j ACCEPT
This is a variation on what I found on other sites describing how to set up a router. I don't understand iptables very well, but I gather that the above two lines should set up forwarding so that traffic from my router to the laptop will be forwarded to the desktop, and vice versa.
But this doesn't work. The connection doesn't even establish between the laptop and the desktop.

Im having trouble with my hp mini 110, i read abit of information about it on the site and installed a package that gets my wifi working, problem being is that as soon as I go upstairs i lose connection, its not really upstairs if I move more than 5 feet away from my router no internet although the laptop reads full signal.
I believe its a problem with the broadcom drivers, is there anyway to resolve this or do I have to go back to Windows 7 because I really dont wanna do that.

I am trying to setup a dhcp server for my internal network. I have two NICs, a modem, and a wireless router. I have my server connected directly to my modem which is providing me with Internet access on eth1 and is working fine. I have dhcp and dns setup on eth0 which is connected to my router. The router shows that it is connected to the Internet but when the router gives a client computer an IP address, the client is unable to connect to the Internet but can connect to the router. I will post my configuration files below with my current configuration.

My son lost his USB Wireless stick for his Computer. I had thought I heard that if you had a second wireless router, you could use it somehow to detect the wireless router you have already set up in your home (like using a wireless card)? Is this what Ad-Hoc is? Either way, can this be done and if so how? I use a WRT54Gx2 Lynksys router and have a TRENDNET TEW-432BRP wireless router and also a spare D-link DI-514. I use ubuntu 10.04, and also wanted to know if I connected one of the router to his on the LAn port could he connect msaybe through an Ad-Hoc on my local computer here? He uses XP on his. I'm a newbie to linux and networking in general.

I'm having issues with my broadcom BCM4313 wireless adapter. Everything works just fine when connected (with additional drivers & Connman), but it takes about 5 minutes to connect to my network when i just started my computer! When resuming from hibernation it goes very quick though, so just when I boot my pc it's taking forever...This is what I found in the dmesg output:
Code:
[ 16.778057] eth1: Broadcom BCM4727 802.11 Hybrid Wireless Controller 5.60.48.36

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'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 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.

My problem is little different then what I've seen here. I get the same message after inputting network name and password. I click connect and it just pops up again I don't get it. I'm running Ubuntu 8.10 for Ppc (PS3) I get no internet connection what so ever just the same message. The message I get is " authentication required by wireless network " What do I need to do to connect wireless to my router with my PS3 using Ubuntu 8.10? It does connect with a Ethernet Wire. I am new with Linux.

I have a router with 2 IBM Thinkpads connected. One Thinkpad is running Ubuntu, and the other is running XP.
They connect to the router with no problems.
I installed Ubuntu on a Sharp Moebius laptop and plugged in the network cable.
NOTHING.
I have tried pinging the laptop; nothing.
I am not sure where the problem is, because my Thinkpads have no problems connecting to the router, with both Ubuntu and XP

my LAN just suddenly stopped working. we had a power outage, and it just stopped. it will still recognize the network, but it wont connect. i was experimenting with setting up a web server (trying to set it up on the standard distro). i know its not the network card (on board) because i can put in my pci card and it still wont connect. it will connect when in the live environment. i thought that maybe it had updated, so i tried to boot from a different (older) kernel. that still didn't help.
i stopped apache. i was experimenting with portforwarding at the time (i had everything else working on my server), but i could not get it to work. after this happened, i restored the original settings on my router. i had applied the settings only a day before the power outage. everything still works on another computer on the network (also running linux). (all computers run 9.10) its almost like my router won't assign me an ip address.

I have a new belkin N1 router which I tested in somebody else's flat. It worked fine. When I got home I reset it by pushing a paperclip in the hole for 10+ seconds to erase this flat's internet connection settings (username and password and stuff). After this I plugged it the computer and tried to connect to it (wired connection) using 192.168.2.1 (this is correct for that router, it is not 192.168.0.1). But the browser says it is offline and cannot connect. The lights of the router cycle, the "modem router" light blinks continuously and the others briefly come on and go off again, every few seconds. I tried resetting it again, several times, leaving it off for a few hours, leaving it on for a few hours, etc.

I recently just upgraded my operating system to Ubuntu 10.04 LTS and I can't seem to get my wireless card to connect to our new Verizon Actiontec router. I am using an Encore Electronics 802.11n Wireless USB Adapter (model: ENUWI-N), which had worked with an earlier version of Ubuntu and our old router. The adapter recognizes the SSID of the new router but will not connect with the correct WEP key or even with the encryption turned off. I have tried deleting the wireless profiles and manually re-creating them and still no dice. I have also gone to the website of the chipset manufacturer and found the latest drivers (RT2870USB(RT2870/RT2770)) for the adapter, which, according to the Synaptic Package Manager, I do not currently have installed.
Where do I go from here? Do I need to install the new drivers, and if so how do I do that?

I wanted to try Ubuntu again but have gone wayback to an old 8.10 disk because I couldn't get 10.10 to work. The install with 8.10 went fine but the internet will not connect. The network manager shows eth0 grayed out and when going in to manage the connection it says 'never'. I'm using Vista with a broadband modem connected to a netgear router.

Now sometimes it detects my wifi router and shows its ssid in nm-applet. but when I try to connect, it tries for 3 or 4 minutes and then fails. for most of time it even does not finds my router.

I have installed ubuntu 10.10 and am really happy. I want to sort the wireless conection out now. I have been through this forum for hours today and can't get it working. I have a Broadcom wireless card, which seems to be working fine, but I am not 100% convinced.I have attached the output of some of the commands that I have seen referred to on here.
I am using the wired connection on the same router, so the router connects fine.I click on the network icon and I see the skyNNNN router in the list. I have tried connecting to it and it asks me for my password, which I provide then nothing happens until it asks me again.I have removed the security from the router and I then see the same skyNNNN router without a
lock icon. I try to connect and it still fails.I am not using an access list on the router, so there is no issue with the mac address.

I'm running Ubuntu 10.04LTS 64bit. The desktop running it does not connect to my router or the internet. My mac laptop does. When I installed windows on this desktop, it too could connect. But after reinstalling ubuntu, I cannot. I tried upgrading to the latest ubuntu, but that just bricks my computer. Here is my ifconfig:
Code:
