Intel Wifi 5100 AGN does not work

[Steelstorm]

Hello,

I am newbie in Linux, and I am using Debian of course and here is my problem.
I have notebook Acer Extensa 5635g, with Intel Wifi 5100 AGN, and it doesnt work.

I googled last two days about it, but I cant get it work.

My Debian version: 6.0.1 Squeeze
Kernel ver.: 2.6.32-5-686

Code: Select all

I have been downloaded ,,new" drivers (of course for my Wifi card) from http://intellinuxwireless.org/ , and I copied iwlwifi-5000-5.ucode to /bin/firmware and reboot, but nothing changed, still doesnt work, ethernet working very well. But I need wifi to work, Network Manager Applet showing Wireless Networks: Disconnected.

Please, write me only commands to Terminal, If u will sned that I need to find, start, or edit some module, I wont know how to do that, all these which I tried (including that Terminal command) I googled, because I am really newbie, but Im techable I know that Debian isnt distro for newbies, but I like it most of all distros.

Thanks for help!

Undo everything you've done there and follow this:
http://wiki.debian.org/iwlagn

[emariz]

As dmesg states, the system misses the appropriate firmware (1). So, remove "driver" that you downloaded, enable the non-free section of the Debian archive, install the package firmware-iwlwifi (2) and restart.

1. http://www.debian.org/releases/stable/i ... 02.html.en
2. http://packages.debian.org/squeeze/firmware-iwlwifi

You seem to have found the right firmware but I am suspicious that your installation has not been successful, based on this:

[ 17.081832] iwlagn 0000:07:00.0: firmware: requesting iwlwifi-5000-2.ucode

[ 17.334257] iwlagn 0000:07:00.0: iwlwifi-5000-1.ucode firmware file req failed: -2

If I am right then we need to reinstall the needed firmware, which is in the Debian repositories. So let's try this:

apt-get update && apt-get install firmware-iwlwifi

That should get you the needed firmware and it should install it properly.

At that point if your wireless still does not work then we at least know you have some other issue.

BTW if you are working at the command-line one of the easiest ways to configure a new Debian system is to use the smxi scripts developed by h2. Visit smxi.org and take a look.

I also delted that driver, which I copied to /lib/firmware.

What is wrong?

[emariz]

Your sources are wrong. Post the contents of /etc/apt/sources.list
For Squeeze, at least three sources should be there, the Debian archive, the security repository and the updates one.

[Steelstorm]

Ok thanks, it works now, I installed that driver normally, like I tried before but now succesfully. I made mistake and edit some other sources.list file, when I added that repo to right sources.list, it was ok. But it is strange, I installed that driver, rebooted Debian, and voilá, my Wifi card working and scaning, but when I connected to my wireless network, filled password, it connected me, but web doesnt work, DNS error said Chrome, ok, I tried reconnect to network, again, again, restart router, connect, again, and nothing, I was connected to my network, but I couldnt go on any web site, and also to local IP of my router!! Really strange, and ethernet connection also stopped working, or works only sometimes, and it isnt in Wired connections, there is: Wired connection: device not managed in NetworkManager Applet. But it was there also before, when Wifi werent working totally (now at least can scan networks, and ,,connect" ) and web via ethernet worked.

So:
if I have eth connected and disabled Wireless -> web doesnt working
when I have eth connected, but after connection of Wifi to my wireless network -> web doesnt working
when I have no eth connected, and Wifi connection to my wir. net -> web doesnt working

And my router is 100% working, I am paralelly connected on my desktop with Windows, without problems.
I have suspicion that problem is now with LAN card driver. But Im not sure.

Look attachments, I uploaded screenshots from admin panel of my router, and from connection information, for sure, if Im not doing something wrong.

And here is some command which I found:

Please recommend me some good repos, please full link, no only ,,u should add experimental", yea I can google, but it is better when Im sure that it is right. I want to have GNOME 3 when I will solve my WIFI problem, so repos where actually GNOME 3 is.

Many users here help those who help themselves. Thus if you don't care to search, read and try, you may not get answers. Debian works if you read.

About your sources list, read this
http://www.debian.org/doc/manuals/debia ... ive_basics
Understand it before editing your list.

About Gnome 3, had you cared to read a little bit about Debian releases, you would know that such an update could never be implemented in Stable.

I know, Im using forum support as last option, when Im lost, and when I searched. But many commands which I found through net last days didnt worked for me (I mean globally, no only for this problem with Wifi card), and when some1 write me to make something in terminal, I dont know what he means, and google doesnt know all, or sometimes I simply dont know what to search. I know some basic commands, and im learning every day No problem for me.

Thanks for links.

But when I will add experimental/unstable repos, I can get G3, right? I know, that stability of system will be less, but it never mind for me. However, Im ex-Windows user, so Im acustomed

This have low priority, highest prioriti is to get my wifi card working. Im totally lost in this area.

Ok problem solved.

BIOS update helped. For those, with same problem:
1. download latest BIOS from ACER website
2. run it in Windows (it is one click)
3. restart PC
4. install Debian
5. install firmware-iwlwifi
