mepis1 · 01-29-2010, 10:57 AM

Hi LQ community,

I Just Upgraded my Laptop from Ubuntu 9.04 to Ubuntu 9.10 and Before I upgraded to 9.10, My Network Was Working Fine, But i've tried installing/upgrading to Ubuntu 9.10 and no such luck.

thanx in advance,

MEPIS1

*Edit* I Upgraded to 10.04 last sunday. it found my network and I now need to figure out how to connect to my network

So that we can better understand your problem, please post the output of the following commands:

Code:

lspci | grep -i net
ifconfig -a
iwconfig

The "lspci | grep -i net" seems to have missed the wireless device. Can you please post the full output of lspci?

eg

Code:

lspci

Evo2.

Your machine doesn't seem to have a wireless chip. So, I did some googling... is this a removable PCMCIA device? Was it plugged in to the slot? Does dmesg report anything after you plug it in?

I think mepis1 is trying to use ethernet, not wireless.
[Edit] No, from the thread title, he wants wireless, but the following might be helpful anyway[/Edit]

You have an IPV6 address. Most people are not using this yet.

Try disabling ipv6. In 9.10 ipv6 is built into the kernel, so you can't just disable the ipv6 module like you used to be able to do. Also 9.10 uses grub2 so things are a little different:

Add the following line to the file /etc/default/grub
Note there is no "#" at the start of this line. Be careful to get it exactly right.

Code:

GRUB_CMDLINE_LINUX="ipv6.disable=1"

Then sudo update-grub
Reboot.

Any better?

Yes It is a PCMCIA card. But I Don't know if dmesg reports anything.

Install the package pcmciautils

Then try this command: lspcmcia

umm tredegar.

Is pcmiautils a local package

minrich · 02-01-2010, 11:23 AM

pcmciautils is on my kubuntu DVD

minrich says it's on his CD, so it's probably on yours.

Anyway, in post #3 it looks like your ethernet cable is connected to something and has an IP address. It might work a bit better if you disabled ipv6 [see above] so then you could at least get connected, fetch the updates (which might of itself help), and any further utilities you need to diagnose and fix your wireless problem.

Please confirm that you have checked that your PCMCIA card is properly plugged in, and the "Disable" switch (if any) is not set.

Does the PCMCIA card work in another computer?

For some diagnostic information, try this:
Boot without the card being plugged in.
Plug it in when you get to your desktop.
Look at the last few lines of the file /var/log/messages
Does it say anything that looks as if it could be relevant ?

Hey tredegar

I tried it....GRUB loads faster but no beans.
