Is my wireless card being recognised?
I have got Ubuntu 10.10 on a Dell Inspiron Laptop. Can't get anywhere with wireless network.
Tried a few bits of poking it blindly with a stick: matthew@ubuntu:~$ lshw -C network WARNING: you should run this program as super-user. *-network description: Network controller product: BCM4312 802.11b/g LP-PHY vendor: Broadcom Corporation physical id: 0 bus info: pci@0000:0c:00.0 version: 01 width: 64 bits clock: 33MHz capabilities: bus_master cap_list configuration: driver=b43-pci-bridge latency=0 resources: irq:17 memory:f69fc000-f69fffff *-network description: Ethernet interface product: 88E8040 PCI-E Fast Ethernet Controller vendor: Marvell Technology Group Ltd. physical id: 0 bus info: pci@0000:09:00.0 logical name: eth0 version: 13 serial: 00:23:ae:32:d4:be width: 64 bits clock: 33MHz capabilities: bus_master cap_list ethernet physical configuration: broadcast=yes driver=sky2 driverversion=1.28 firmware=N/A latency=0 multicast=yes resources: irq:44 memory:f68fc000-f68fffff ioport:de00(size=256) *-network DISABLED description: Wireless interface physical id: 2 logical name: wlan0 serial: 00:24:2c:3d:cf:dc capabilities: ethernet physical wireless configuration: broadcast=yes driver=b43 driverversion=2.6.35-22-generic firmware=N/A multicast=yes wireless=IEEE 802.11bg matthew@ubuntu:~$ I reckon *-network DISABLED is a problem, I tried sudo ifconfig wlan0 up but that didn't work. The output of that and lspci are on the ubuntu side of my machine. I have also tried pressing my wireless on/off key (F2) but that doesn't work either. Any ideas please? |
Because of license restrictions Ubuntu can't integrate the necessary firmware for your wireless card into the distribution, so you have to install it with either your hardware helper program, or from the command-line with
Code:
sudo apt-get install firmware-b43-lpphy-installer |
Thanks Tobi.
I tried what you said and got Code:
matthew@ubuntu:~$ sudo apt-get install firmware-b43-lpphy-installer |
OK, you have to connect with a wired network first, and then run
Code:
sudo apt-get update |
The built in wireless card gets recognised now and works, I can see several wireless networks. When I try to connect to mine, I'm unable to get the network to recognise my password....
With a plugged in connection: Code:
matthew@ubuntu:~$ ifconfig |
Sorry, don't know anything about IPv6. Did you try to connect without a wired connection?

Yes, it works fine when I used wired internet (eth0). The code I posted was the ifconfig output when I had it plugged into the wired ethernet. It looked the same when I unplugged the ethernet cable, except eth0 wasn't there. Using the wireless network manager, I was able to change to another wireless network and put in the password for that network, and it worked. But that was breaking the law, strictly speaking, as it wasn't my wireless network and I just guessed the password.
When I put in the password for my wireless network, the network manager icon flickers up and down, then I get asked again; I can never get an internet connection. ifconfig never shows a private IP4 address (e.g. 192.168.0.2); just an ip6 address. |
I have seen where the DHCP6 client caused a problem with a wireless router. (This was on Vista) You could try disabling IPv6 support or at least the DHCP6 client.
The DHCP negotiation occurs after authentication. Check your logs to see if you authenticated successfully. If you have, then it may be an IPv6 issue. If you haven't, then it doesn't get to the DHCP phase, which is why you don't get an address. |
You also can try to disable IPv6 in your router.
