Pflanze2: /* LED doesn't turn on */ patch to solve that blink

* [[Gentoo]]
** I got the same problem with this card as below. I need to remove driver (rmmod iwl4965) and load it once more to make new connection. Sometimes I also need to turn wireless off and on via hardware switch then reload driver modules and then KNetworkManager finds wireless networks and I can connect. Quite irritating thing, but when it make connection it has high power and low latency.

* [[Kubuntu Feisty]]
** I can only get the adapter to make one wireless connection per boot. If I get kicked off wireless or I try to change AP's I have to reboot. The restricted IPW driver tends to destabalize the system. The IWL driver is much more stable but still has the same connection problem. Any thoughts?? Lenovo R61i.

** [quote]Works out of the box in edgy. Requires restricted repository.[/quote]
Are you sure? I installed Networkmanager (from main - I have a WPA enabled router) and WiFi worked immediately. No need for any additional tasks.

** With Edgy, all you have to do is install the linux-restricted-modules-generic package.
It works out-of the box in edgy (on a {{Z61m}}) without the need to install any additional packages, so I changed this info.

*{{Ubuntu}}
** Ubuntu Dapper has already built in this drivers; it works out from the box.

Ubuntu (neither Dapper nor Edgy) have the ipw3945 drivers, so I've deleted the info.

According to this:
http://www.digitalvampire.org/blog/articles/2006/09/29/ubuntu-edgy-eft-on-a-thinkpad-x60s-how-to-make-ipw3945-work

All you have to do is to install the linux-restricted-modules-generic package. I've tested this using Edgy - it worked out of the box on a T60.

== Sharing experience ==

I understand that considerations below might not necessary be of importance for everybody, however since I owe this card I thought I share few of my own experiences with it.
Card:
1) lacks promiscuous mode sniffing capability in Windows (which I feel is must for most network techs and security oriented people).
2) does not work with aircrack tools
3) in order to see what is current signal strength it is necessary to hover mouse over icon on taskbar and read info from pop-up baloon (bit irritating). Strengths are shown as “Good”, “Fair”, “Poor” etc. I feel much preferable way of displaying signal strength is to present users with dynamically changing visual meter in card utility, which show signal in decibels as oppose to say “Fair” - God knows what and how many db.
4) to see what type of encryption network use (as visible in all networks view) in cards utility, it is necessary to hover mouse over a network name and read info from pop-up balloon (irritating again).
5) values from network properties as MAC for instance cannot be copied to clipboard.
6) to my knowledge it is not possible once card is installed, to disable cards connection managing utility and allow Windows to manage wireless connections.

* Most of the above points seem dependent on the software you use, not the card or driver. Using "iwconfig wlan0" I can see "signal level" in dBm (and it seems precise). The aircrack tools work for me too except for aireplay-ng (but then maybe I'm doing something wrong). --[[User:Pflanze2|Pflanze2]] 12:36, 11 October 2009 (UTC)

== My wireless works on Ubuntu 8.04, but I cannot connect to wireless N ==

In windows in order to connect to my Wireless N network (WTG300N) I need to setup my auth as WPA2 with AES. This is the only way it will work. I've tried to configure that manually with linux and automagically with wicd, but neither of them allow me to connect to my network. I keep getting "wlan0: AP denied association (code=18)" errors in my syslog. Any ideas on what I can do?

In /etc/network/interfaces i have
<pre>
auto wlan0
#iface wlan0 inet dhcp
iface wlan0 inet static
address 10.0.0.110
gateway 10.0.0.1
dns-nameservers 10.0.0.1
netmask 255.255.255.0
wpa-driver wext
wpa-ssid <MYNETWORK ESSID>
wpa-ap-scan 1
wpa-proto RSN
wpa-pairwise CCMP
wpa-group CCMP
wpa-key-mgmt WPA-PSK
wpa-psk <MYKEY>
</pre>

== 802.11n support as of kernel 2.6.25 ==

I managed to get 802.11N to work work with my [http://www.dlink.com/products/?pid=565 D-Link DIR-615] AP by building my own kernel on Ubuntu 8.04, and with the stock 2.6.25 kernel driver on Debian unstable.

The wireless tools do not yet (July 2008) support N. If you're seeing a bit rate of 0 Mbit/s with iwconfig, you're hooked up correctly. :-)

== LED doesn't turn on ==
Wireless works fine, but the wireless LED indicator get never turned on

* I've got another problem, it turns on for me but with wpa_supplicant the LED is always blinking. I'm using this to switch it to constant light (but the blinking reappears after a couple hours):
echo 255 > /sys/class/leds/iwl-phy2::radio/brightness
--[[User:Pflanze2|Pflanze2]] 12:39, 11 October 2009 (UTC)

I've now solved it by patching the driver, see http://paste.debian.net/48771/

== Finding out which adapter you have ==
For MiniPCI or Cardbus adapters run the command:
:{{cmdroot|lspci -n <nowiki>|</nowiki> grep "Class 0200"}}
If that produces no output, run this command instead:
:{{cmdroot|lspci -n <nowiki>|</nowiki> grep "0200"}}

Alternatively, grep for "0280" which identifies "Network" controllers, as opposed to "0200" which identifies "Ethernet" controllers.

And compare the PCI IDS with the ones below.

In case the PCI IDs are not listed here, "lspci|grep -i wireless" could be helpful.

{{NOTE| This will also return the PCI IDS of any Ethernet adapters, as Ethernet adapters and Wireless adapters share the same PCI Class ID.}}

=== Error 1802 - "Unauthorized" MiniPCI network card ===
Attempts to install an unsupported card will result in the following message:

1802: Unauthorized network card is plugged in - Power off and remove the miniPCI network card.

For a resolution, see the [[Problem with unauthorized MiniPCI network card]] page.

=== Hardware Transmitter Switch ===

Operating a radio transmitter is not permitted in aircraft, and there are times where security requires that your wireless connection be shut down. Some ThinkPads with internal MiniPCI wireless cards have a hardware switch that disables the wireless network. Here it is on the '''on''' position:

[[Image:Wireless-switch.png|(ThinkPad R60 radio switch in the ON position)]]

To be certain that your wireless connection is not transmitting, turn the switch '''off'''. Just remember to turn it back '''on''' when you once again need wireless access. If the switch is '''off''', you might encounter a message like the following Log-Message on Startup:
ipw3945: Radio Frequency Kill Switch is On:
Kill switch must be turned off for wireless networking to work.

Also, when you try to activate (iwconfig) your wireless connection with the switch '''off''' you may see the error,
Error for wireless request "Set Mode" (8B06)
The number 8B06 merely represents the wireless mode (auto, ad-hoc, managed, master), none of which will work with the wireless switch '''off'''.

== Cardbus adapters ==
Cardbus is a 32bits bus that runs at 33MHz, and is in many ways simular to the PCI bus. In fact under Linux Cardbus adapters are handled by the PCI subsystem. 
You can differentiate a PC Card adapter from a Cardbus adapter as the later has a gold coloured grounding strip
