So, I installed Gutsy last night with the alternate install cd (I tried first with the live cd, but it didn't seem to work). And now I can't get wired or wireless internet.

By default, it's trying to use ath0:avahi, but it says that something's missing in /proc/net/something.

And it won't recognize my wireless card either. This was also the case in Feisty, but I solved it with madwifi, using the instructions here http://forum.thinkpads.com/viewtopic.ph ... highlight=. I downloaded both those files onto a thumbdrive and brought them into Gutsy, but I can't untar the madwifi file. I downloaded the latest release from madwifi.org, but got a number of errors when trying to make it.

The wireless card is an Intel Pro 3945ABG, if that helps at all.

Also, for some reason, I can't select any resolutions that are widescreen. It only gives me options for 4:3 resolutions. If you know how I can fix that, I'd also appreciate it.

Thanks for the help

Can you please post the error messages you're getting plus the output from

Code: Select all

ifconfig -a

?

To get wired internet working, if you're connecting over a network with a dhcp server (e.g. a dsl router provides dhcp usually) try the following:

Code: Select all

sudo ifup eth0
sudo dhclient eth0

You shouldn't be using the madwifi with an Intel 3945.

The correct driver would be ipw3945 (can be activated using the “Restricted Drivers”-applet in control panel or iwlwifi if you want to go oss-only.

The restricted drivers manager doesn't show anything other than the ati drivers. Is there something I need to download first?

I'm getting wired internet at my neighbors, but for some reason not at my place. when I get back to my place, I'll try ifup and let you know how it goes.

according to what you posted there, you won't need ifup and dhclient since you are already connected to the local network and have an IP.

Let's have a look at your route:

Code: Select all

route

make sure the default route is set to your router (if you are using one) or company gateway or whatever is connected to the internet.

if that's correct, try

Code: Select all

traceroute google.com

if google.com can't be resolved, have a look at your /etc/resolv.conf

Is this for my wired connection? I don't think there's any problem there. I tried connecting directly from my modem at home to my computer in windows and couldn't get any internet either. It only works if I go through my router for some reason. But when I connect through my neighbor's router, I get internet fine.

The problem is that it's not recognizing my wireless card.

ah ok then I misunderstood, i thought there was an issue with both

about the wireless, make sure you got "universe" in your repositories.
Also found this thread, maybe it's of some help: http://ubuntuforums.org/showthread.php? ... ht=ipw3945

Maybe something went wrong during your install? Did you check the MD5sum of your ISO's before burning them?
You can install with the regular CD but you have to boot into "Safe Video Mode" Then install.
Installing the restricted video drivers should help your resolution issues.

Posted: **Mon Oct 22, 2007 10:37 am**

I fixed my video resolution by using the restricted graphics drivers. But still have no wireless drivers.

I've reinstalled a couple times with no success. But I haven't check the MD5sum. Everything works fine except the lack of wireless drivers. Could a corrupted iso be the cause of that?

How do I check the MD5sum? And how do I boot into save video mode? Thanks.

Posted: **Mon Oct 22, 2007 11:51 am**

To check the md5sum in Linux, open a terminal/konsole type

Code: Select all

md5sum

hit the spacebar and drag and drop the ISO file onto the terminal, hit enter. It will grind for a while and produce a number. This number should match the md5 number posted on the ubuntu download site. If not the download is corrupted and could cause any imaginable installation issue.

When booting from the live cd there may be a selection to check the integrity of the cd. If so try that too.

To boot to safe video mode, put in the regular ubuntu cd, boot to it, at the first menu arrow down one selection to "Safe Video Mode" and hit enter. Then it will boot to the live cd where you can click the "install" icon on the desktop. This will install ubuntu from the regular cd.

I tried to install using the live cd, but even in safe mode it didn't properly display. I'm going to try reinstalling feisty and then upgrading, but if you have any other things to try, I'd really appreciate it.

Posted: **Mon Oct 22, 2007 5:22 pm**

try calling the restricted manager with the check (-c) and update (-u) parameters.

sadly i don't have an ubuntu here right now but I think i still got an install on some pc at home, will take a look at that restricted manager.

But at least you get a display. It is still running vesa at that point so it won't be 100% right but it will allow you to see what you are doing to get ubuntu installed. Once it is installed you go to the "K" menu/System Settings/Advanced tab and click the "Restricted Drivers" icon. Then you can install the video drivers so it displays correctly.
I haven't tried installing ubuntu on a Thinkpad with a 3945 card yet, maybe later this week, but I have installed it on a R61 with the 4965 card and it works right out of the box. The 4965 is much more difficult to get working than the 3945 is.

Posted: **Mon Oct 22, 2007 8:43 pm**

Well, I couldn't install through the live cd. It just gave me a command prompt then black screen then back to a blown up command prompt. Then said the video driver wasn't working.

I'm back in gutsy now, though.

Here's the output of lspci -v for the network card, if that helps at all.
