No Option for wireless connection

[JayDub]

So I am trying to figure out how to use wireless with linux mint.

When I right click on the network manager the only options that I have are "Enable Networking" (checked), "Connection Information" and "About". I am able to connect to the internet via a wired connection but I have not been able to find out how to connect wirelessly.

Currently my /etc/network/interface file has the following in it:

auto lo
iface lo inet loopback

And I tried following the steps suggested in viewtopic.php?f=90&t=2577 but it did not help.

Running mintWifi.py gives me this output:

Undoubtedly you had the wired connection connected when you ran mintWifi...
Follow the wiki
http://www.linuxmint.com/wiki/index.php/MintWifi
If you read french a solution here (I think you can make something of it even without understanding french)

The first place I tried was the mintWiki but it didn't help me problem.

When running miniWifi.py without being plugged into the internet it returned these results:

Of course - how could I forget http://www.intellinuxwireless.org/
Thanks MagnusB

Well, Husse, I have had some troubles with the iwl module, so I will not forget it You are very much forgiven, we do not expect you to remember every solution to every problem
As for for the trouble at hand, iwl module is included in the kernel, so it should work at boot, so somehow Mint screwed that up, it could happen for no appear ant reason.
The module is called ipw3945 (I use iwl4965, that is why I screwed that up).
First, it depends on two modules, iwlwifi and mac80211. First you need to see if the microcode is present:

Code: Select all

% sudo updatedb
% locate iwlwifi-3945.ucode

It should be located at /lib/firmware/2.6.22-14-generic (in Daryna without an updated kernel), if it isn't:

Code: Select all

% wget http://intellinuxwireless.org/iwlwifi/downloads/iwlwifi-3945-ucode-2.14.4.tgz
% tar xvf iwlwifi-3945-ucode-2.14.4.tgz
% sudo cp  iwlwifi-3945-ucode-2.14.4/iwlwifi-3945.ucode /lib/firmware/2.6.22-14-generic

Then see if iwlwifi is loaded:

Code: Select all

lsmod | grep iwl

if that returns squilch, try:

Code: Select all

sudo modprobe iwlwifi

Then check for mac80211:

Code: Select all

lsmod | grep mac

Again, if that returns zero:

Code: Select all

sudo modprobe mac80211

If everything went successful, reboot and you should have wifi If not, and you have some troubles compiling the modules, please feel free to ask
