it appears that the wireless option is not even being recongized at all in the ifconfig or iwconfig which has me quite worried

i'm using hardy heron on a dell mini inspiron 1210

Hi,

Please first connect your network card to the wireless router using an ethernet cable (also known as a LAN cable).

In order to gather essential troubleshooting information about your wireless card, please follow this procedure:

Step 1: Open Terminal from "Applications->Accessories->Terminal"

Step 2: Please copy-paste the following command from the https://answers.launchpad.net/ubuntu website in Firefox into the Linux Terminal. Do NOT copy-paste from the Email message into the Terminal, as that will only copy PART of the command. The command STARTS with the word sudo and ENDS with the word restart. So please copy-paste the ENTIRE command below from Firefox into a Terminal, press <enter>, then enter password when sudo asks for password, then press enter again.

sudo lshw -C network; sudo iwlist scanning; cat /etc/network/interfaces; cat /etc/lsb-release; lspci -nn; lsusb; sudo lshw -C usb; uname -a; dmesg | grep ound; dmesg | grep b43; dmesg | grep iwl; iwconfig; sudo /etc/init.d/networking restart

Step 3: Please post results (copy/paste terminal output) on this thread

Regards,

Mark

It is definitely strange that the command lshw does not work on your pc. I checked and you did copy-paste the command correctly. This issue may point to a broken Ubuntu install.

Try installing the Ubuntu 9.04 NetBook Remix Image to a USB stick, then boot from the USB stick and send us the output of the following commands during the LiveUSB session:

sudo lshw -C network; sudo iwlist scanning; cat /etc/network/interfaces; cat /etc/lsb-release; lspci -nn; lsusb; sudo lshw -C usb; uname -a; dmesg | grep ound; dmesg | grep b43; dmesg | grep iwl; iwconfig; sudo /etc/init.d/networking restart

See if you can get the command lshw to work in the LiveUSB session.

Here are the installation instructions:

I hope this advice will help.

so i dont have a flash drive at the moment, but was thinking would it be worth while to try to upgrade to intrepid ibex, or jaunty jackalope
or try to do a complete install of the programs instead? i dont care if i lose all my data.

i tried to run my update manager and the following message came up:
W: GPG error: http://ppa.launchpad.net hardy Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 3F2A5EE4B796B6FE

and i have tried to upgrade my system before and the directions are insanely easy but when i open up the software sources, under the updates tab, i dont have an option for release upgrades which is weird
the only thing i see is a part about automatic updates

here is my third party software and authentication

First try this procedure:

If that one does not work, try this one instead:
