Where is the wireless drivers in Ubuntu?


I am trying to connect my fresh new Ubuntu 10.10 to my router. However I am having a bit of difficulty.

This is what I have done so far:

Code:
lspci
My devise is a Broadcom Corporation BCM4311 802.11b/g WLAN (rev 02).

Then:
Code:
sudo ifconfig eth0 up
sudo iwlist eth0 scan
I get eth0 Interface doesn't support scanning.


Any suggestions.....?

Have a look in proprietary drivers for the STA driver - should be available for download. You'll need an active (wired) connection.
11.04 has it on the install CD, so avoids the wired requirement.

I don't believe eth0 is your wireless card, it should be wlan0, eth0 is most likely your ethernet.

Also, that Broadcom card needs firmware that is not allowed do be distributed with Ubuntu. The driver comes in the kernel, it is the b43 driver.

This should tell you everything you need to know.

You are probably correct. eth0 is probably ethernet, but all that is listed in ifconfig is lo and eth0.

I am assuming that the OS is not seeing the wireless nic is because there are no drivers installed for it? The only problem with that is that lspci sees the devise. Confusing?

I will go get the drivers and go from there.

Before anyone asks, yes I am sure the wireless card exists. If it didn't lspci would not have printed it out.

Any help would be great.

true

Nope. Ubuntu choose not to load the driver automagically.

It is probably not showing up because you don't have firmware, the drivers are there, they are part of the kernel. Also, lspci shows everything on the PCI bus whether or not drivers exist for it or not, there is a little ID chip in every piece of modern hardware with number in it to tell the OS what it is. If you run "lspci -nn", you'll see the number it gives.

Post the output of "dmesg|grep -i b43", I think it will show the driver trying to load, then failing because of missing firmware.

Elliot678,

Here is my output:

Code:
sudo dmesg | grep -i b43
[     1.400581] b43-pci-bridge 0000:03:00.0: PCI INT A -> Link[LK1E] -> GSI 19 (level, high) -> IRQ 19
[     1.400602] b43-pci-bridge 0000:03:00.0: setting latency timer to 64
[    16.486217] b43-phy0: Broadcom 4311 WLAN found (core revision 13)
[    16.943481] Registered led devise: b43-phy0::tx
[    16.943541] Registered led devise: b43-phy0::rx
[    16.943591] Registered led devise: b43-phy0::radio
The output for lspci -nn is:

Code:
03:00.0 Network controller [0280]: Broadcom Corporation BCM4311 802.11b/g WLAN [14e4:4311] (rev 02)

I don't understand why this thread is still going.
IMHO you really don't want to be using b43 at all - read (and follow) the instructions in the link in post #3.
Use the STA instructions - simple if you have a wired connection. Pretty painless even if you don't.

Why cant I connect? I am lost, I did all the things I am supposed to as far as I know.



I completed the directions on the Ubuntu site, by doing the following:

System>Admin>Synaptic Package manager>bcmwl-kernal-source and installed it.

Then I did:

System>Admin>Additional Drivers, to activate the driver.

In the Wireless Tab, I configured the following:

SSIS
Mode: Ad-hoc
Band: B/G(2.4 GHz)
Channel: default
BSSID: 00:00:00:00:00:00
MTU: automatic

Omitted the mac address devise/clone

On the IPv4, I configured:
Automatic (DHCP)addresses only
I checked "available to all users"

On the IPv6, I configured:
Automatic, DHCP only
I checked available to all users

Wireless Security uses WPA and WPA2 Personal
and the password is entered.


I would appreciate any help so I can get this thing on the Internet so I can actually use it without a hardline.

Shaun

Why are you using DHCP for addresses only ?.
I don't know, but I'd guess this precludes the router from providing gateway services.

ok, so I tried Automatic(DHCP)on the IPv4 and Automatic on the IPv6. Still no connection.

Do I need to provide the DHCP client ID? Do I need to provide the Devise MAC addresses and/or the Cloned MAC addresses?
