Ubuntu trouble

[lucid]

I recently created a bootable USB and installed ubuntu 10.04.4 on it. Previously I had ubuntu 11.10 but I hate Unity and the whole thing kept crashing so I reverted back to an older version. I plan on waiting for the next LTS version anyway so heres my question.....
I've been running the live version of 10.4 and it won't connect to the internet. More specifically it can find any connections whatsoever. So I did a hard connection and it couldn't even read that. I've searched google thoroughly and so far can't find much.  Has anyone else had this problem?


P.S. I have a Broadcom 802.11 network adapter. Also an Atheros PCI-E Fast Ethernet Controller(not sure if that part matters)

List hardware device using "lspci" or perhaps "lspci | grep "network"" and "sudo lshw -C". If you see nothing about Broadcom or any network adapter drivers are probably not installed.

Find the exact model of your network adapter (most likely on windows device manager) and find the linux drivers online. Put the drivers on a USB key, boot ubuntu and install drivers.

One thing that sucks is that sometime even if you have a persistent install on your USB key you'll have to install the drivers every time you boot. I had this problem with a 9.10 live USB a while ago and I "fixed it" by making a script that would install the drivers when a user logged in. Lots of fun (not really)

Even with persistence huh. Damn. Well I suppose the next step then would be to install ubuntu. Unfortunately this little USB is my computer for now(I'm on someone elses)

Anyway thanks alot thats quite helpful

if you see it under lspci that means it's connected to the computer if you want to see if the modules that are loaded, lsmod so you can determine if its hardware of software, unless you know its an driver then you can see if the module is loaded or not.

Do I have to disable any WEP WPA or MAC security temporarily?

My god man. Broadcom and Ubuntu is not a very good combination. What Satan is said is true, but it won't work as simply as that with Broadcom.

Lucid is having the same problem I did, and I tried lots and lots of solutions, read a lot and tried those opensource broadcom linux drivers: http://linuxwireless.org/en/users/Drivers/b43
Official broadcom drivers for linux was useless too.

Shit just refused to work every time.

I eventually solved it, and it was very simple - I found the solution somewhere on 50th google page or something
Here's how I did it:

Seems that Ubuntu 10.04 does not support Broadcom fully or something, so it won't initiate the wireless device (ethernet was working fine), event tho lspci detects it. So I booted up my main Ubuntu installation as normal (10.04) and popped in the Ubuntu 10.10 CD, which I had since it came out.
When the CD gets mounted (guess it would work when you mount the image as well), Select (in Gnome menu) System -> Administration -> Hardware drivers.
It will search for drivers and give you to select which to install (for me it only one - broadcom). Then you just press on the red circle, select to use it (can't remember the exact procedure) and it should install all those drivers.
You will have to reboot after this.

Also a side note: I noticed that "Wicd network manager" works better than that default Ubuntu network manager.

Tell me how it will work for you

EDIT: Shizzle, I remembered you wanted to fix for a LiveUSB.
Sorry bro, this is when you install it to the drive.

[lucid]

Thanks But sadly yes all I can do is boot it from my USB. I think I'm just going to have to wait for 12.04. Does it come out right at the beginning of april?

[Kulverstukas]

yes it does. They always release at the first day.

[lucid]

Awesome. I'll be getting that shit the day of....I guess theres only so much one can do on a live boot.....god I need a fucking computer.

[Satan911]

The final release is set to be released on April 26th.

I imagine its going to be running a Unity environment?


Thanks for the advice everyone.

[FuyuKitsune]

Yes but you can always changed that.

[noob]

You can put 11.10 and disable unity if your wireless work well

Since I got my own computer now I can install 10.4. Would this technique work with something other that 10.10? Still a whole month till the final release of 12.04 so I might as well work with this for awhile


EDIT: Damn, made a live usb for 10.10. No network connections on that one either. Maybe I really just have to wait for 12.04

Code: [Select]

Network controller: Broadcom Corporation BCM4318 [AirForce One 54g] 802.11g Wireless LAN Controller (rev 02)
I got that one, as shown by lspci.

Driver that worked for me

Code: [Select]

http://www.multiupload.nl/5DPDIAZCD2I downloaded that to desktop

Code: [Select]

sudo mkdir /lib/firmware/b43
sudo cp Desktop/b43/* /lib/firmware/b43
sudo rmmod -f b43
sudo rmmod -f ssb
sudo modprobe b43
As soon as the last command ran, wireless popped right up. Worth a try if you haven't got it to work yet.
