Connecting to a Wireless Network

Hey, I hate to pester, however I am very new to linux and #! in general. I've installed the newest version of #! on my Optiplex 790 yesterday, and still haven't been able to establish a connection to a wireless network. I've been searching this forum up and down and even the master howto list to no avail. Is there anyone here willing to walk me through this simple task, aha?

Also, I've learned about the whole lspci thing, and noticed I don't have any Network information like some others. Is that irregular or is it simply because I'm not connected? Thanks in advance!

Re: Connecting to a Wireless Network

hello dazzl-o, here is a sticky thread you should read (and act upon), apart from the forum guidelines and some more general how-to-post articles elsewhere.
btw, your problem is very, very common and has most probably already been solved more than once on these very forums. you notice the magnifying glass in the top right corner?

edit: oh, and welcome to the forums! we will sort it out together eventually!

Re: Connecting to a Wireless Network

Thank you, ohnonot! I apologize for not reading the sticky you referred. I'm posting from an alternate machine, so I can't exactly copy/pasta all of my outputs from terminal given that some of them are rather long.
uname -rv

3.2.0-4-amd64 #1 SMP Debian 3.2.41-2

lspci -khn | grep -EiA2 net

00:19.0 Ethernet controller [0200]: Intel Corporation 82579LM Gigabit Network Connection [8086:1502] (rev 04)
Subsystem: Dell Device [1028:047e]
Kernel driver in use: e1000e

Now the dmesh|grep -Ei 'wlan|firmw|dhc' onward is too long for manual copy, but the first line does seem problematic to my green eyes:

[0.484206] [Firmware Bug]: ACPI: BIOS _OSI(Linux) query ignored

I'd also like to apologize if any of this is no-brainer solution stuff, I'm rather new to studying technology and still learning, wanting to add Linux to my plate as well, aha.

Re: Connecting to a Wireless Network

Hello Dazzl-O, welcome to #!
It sounds like you are lacking the firmware for your wireless card.
Was the wireless working in the live environment?
You could try downloading the backported kernel as a .deb file & install it with:

sudo dpkg -i <name of the linux-image.bpo>

You may also need the backported initramfs-tools...
To place the newer kernel at the top of your GRUB menu, run:

sudo update-grub

The newer kernel might support your wireless card smile

Re: Connecting to a Wireless Network

Thank you very much! I'll have to try that when I get a working Ethernet cable for the Optiplex. I'll edit this post, and hopefully the thread title, when I manage some results. Thanks a lot you two!

Re: Connecting to a Wireless Network

ok, we're waiting.

just some explanation:

this is the most important bit!
on my system the output of that command (i guess you meant dmesg, not dmesh) is only 2 lines.
many lines means many warnings and errors!
