Cannot access internet via ethernet or wireless (HP dv6500)

I installed Ubuntu 9.10 on my Samsung netbook with success (I'm using it to post now). However, I just finished installing it on my HP dv6500, and now I cannot access the internet (either through wireless or via the ethernet cable).

Wireless access would be nice, but it's not crucial, as I use this computer mostly at my desk anyway. However, ethernet access is very important, and I'm confused by why it's not working (the same cable works on my netbook as soon as I plug it in). Any advice?

Are you using DHCP? Post your /etc/resolv.conf file.
Post the result of /sbin/ifconfig and /sbin/route.
Can you ping a LAN address such as the netbook? Can you ping the router? Can you ping an Internet address such as 8.8.8.8?

Try to resolve an address:
getent hosts www.google.com

Post the output of

Code:

lspci | grep -i net

lsmod

Whoops, my mistake. It turns out that the ethernet connection is, after all, working. Wireless is still a no, though.

Code:

lspci | grep -i net

gives me

Code:



00:0a.0 Ethernet controller: nVidia Corporation MCP67 Ethernet (rev a2)

03:00.0 Network controller: Broadcom Corporation BCM4311 802.11b/g WLAN (rev 02)

and

Code:

lsmod

gives me

As for getent hosts www.google.com, I get

I imagine that this might be a driver issue - when I check under Hardware Drivers, I see two for my graphics card, and then both Broadcom STA wireless driver and Broadcom B43 wireless driver. For my graphics card, one of the two is recommended, but neither one is marked for the wireless card. Could this be the issue?

Yes. You want the b43 driver. Well, to be accurate, you are loading the b43 driver currently, but it needs extra non-free firmware. You can enable it from the Hardware Drivers GUI, or from a terminal do

Code:

sudo apt-get install b43-fwcutter

Alright, thanks for that. However, I'm having problems accessing the Hardware Drivers GUI. First, it takes a ridiculously long time to search for available drivers. Then, if I am able to view the list, when I tried to install the graphics card driver, it stops at about 30%. Doesn't freeze, but doesn't progress.

I tried the above command in the terminal, and I get

Use 'apt-get autoremove' to remove them.

This would indicate there is another instance of the package manager running. Make sure you do not have Synpatic open, or the update manager, or anything like that.

No, I closed everything (even Firefox) and tried it, and I still get the same problem/output...

Can you post the output of

Code:

lsof | grep /var/cache/apt/archives/lock

When I do

lsof | grep /var/cache/apt/archives/lock

the cursor blinks and it looks like it's processing something for a while, but then I just get back to the prompt (with no output).

Ok. Hrm, been awhile since I used a Debian based system, but I believe you can just remove the file.

Code:

rm /var/cache/apt/archives/lock

And try again

Code:

sudo apt-get update && sudo apt-get install b43-fwcutter

Success! Thanks for the help - now I was able to install both the wireless driver and the graphics driver. For the record, what exactly was I trying to remove with the rm command?
