No network connection

[Alxl]

Installed Ubuntu 9.04 on an older Dell laptop. Everything seems fine except that I cannot get online.
I am new to Linux but tried to read about this problem and entered lspci and also lshw -C network as was suggested and here is what I got.
Hope somebody can help (I am writing this on another laptop)

[Iowan]

How are you trying to connect - wired, wireless (either)? Attempting to get address via DHCP?

[Alxl]

this laptop has dual boot XP and Ubuntu 9.04. No problem getting online in windows.

I can that something is disabled:

*-network:0 DISABLED -network:1 DISABLED

but how do I enable one?

Thanks

[Alxl]

sorry Iowan - I did not see your post before I posted again.

I am trying to get online wireless . I have cable for the main computer and a router which works for another laptop .

what is DHCP ?

[Iowan]

DHCP (http://en.wikipedia.org/wiki/Dynamic_Host_Configuration_Protocol) is Dynamic Host Configuration Protocol. In essence, it means your computer gets an IP address by asking for one - you don't need to manually enter the information. In many (most?) home networks, the router is also a DHCP server.

[calrogman]

Can you post the output of `lsmod` and `dmesg | grep b43`?

[Alxl]

To run a command as administrator (user "root"), use "sudo <command>".
See "man sudo_root" for details.

[calrogman]

Please run
sudo aptitude install b43-fwcutterWhen prompted whether or not to fetch and install the firmware, enter Yes.

[Alxl]

b43-fwcutter installed with no problems.
I rebooted and still no connection to the router

[calrogman]

Post the output of `lspci -vnn | grep -i 14E4` please.

calrogman (http://ubuntuforums.org/member.php?u=674525),

I looked at the thread but it refers to version 8.10 and specifically says that it will not work for other versions (I have 9.04 installed on this laptop).

I also have Ubuntu 8.04 on a USB stick and started the laptop with this USB without installing - works good but still no internet.


Do you think I should try the latest version of Ubuntu still in beta?

Hope that somebody can help

I

[Alxl]

still no internet.
I was wandering if Ubuntu 9.10 may have new drivers to get online easier.
Any help appreciated.
Thanks

[Alxl]

As a follow-up, all that was needed was a driver: " Broadcom B43 wireless driver ".


I installed Ubuntu 9.10 and it promptly said that the driver is missing. After downloading same, machine works fine.


Thank you all for your input
