 Posted: Fri Mar 04, 2005 5:30 pm Post subject: wireless with ipw2100 |
 |
|
Hello good people of gentoo,
I installed gentoo using the universal live cd that I had with me which is 2004.3. So my portage tree was not the latest one. I emerged ipw2100 with kernel 2.6.9 r1 (using the appropriate modifications on the kernel). The following command got my wireless at eth0 up and running:
| Quote: | modprobe ipw2100
iwlist eth0 scan
iwconfig eth0 essid "my network name" |
Since I had my network working, I updated my portage tree. I then emerged kernel 2.6.10-r6 (the latest version that was avalable), compiled the kernel. Then I did
| Quote: | | emerge --fetchonly ipw2100 |
Then I rebooted into the new kernel and emerged my downloaded ipw2100.
not modprobe ipw2100 works.
tells me eth0 cannot be scanned. Apparently eth0 does not exist or someting like that.
So I thought my previos kernel might stil work. So i rebooted into 2.6.9 and emerged the new ipw2100 that I had. My wirless gave me the same message when I did iwlist eth0 scan.
what seems to be the problem here? is it that there is a file that I need to modify?
thanks |

Well, there are some specific requirements for getting ipw2100 up and running. First you need these packages:
| Code: | # net-misc/dhcpcd
# net-wireless/hostap-driver
# net-wireless/ipw2100
# net-wireless/wireless-tools
# intel wlan driver for WindowsXP
# ndiswrapper |
And then you need to add support for the Cryptographic API in your kernel, as the ipw2100 driver needs it for WEP support. It can be found here:
| Code: | Cryptographic options --->
[*] Cryptographic API
<*> ARC4 cipher algorithm
<*> CRC32c CRC algorithm |
And then you should be able to modprobe it after a reboot.
If it works you can add "ipw2100" in /etc/modules.autoload.d/kernel-<kernel version> to autoload the module.

all those are installed except for ndiswrapper.
why would i need ndiswrapper and wlan driver for windows xp though?
Isnt ndiswrapper and ipw2100 different methods of connecting to wireless.? |

Well I don't think you HAVE to use it. The first tool that was known to emulate the NDIS structure of the win-drivers for the Intel 2100 Pro was the tool 'ndiswrapper'. But you can use whatever you like afaik.
If they are installed, try:
| Code: | | /etc/init.d/net.eth0 |
Or:
| Code: | ifconfig eth0
dhcpcd eth0 |
Do you have WEP encryption on your router? If yes, then you need to use the command iwconfig to specify it. Read more at:
http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?full=1#wireless

Those are the messages I get with trying to start my wireless device.
what is the [!!] trying to say that there was an error.
is there a conflict somewhere? |

Try:
| Code: | # modprobe ipw2100
# ifconfig eth0 up
# dhcpcd eth0 |
And then use iwconfig to specify your wireless settings.
If you don't use dhcpcd then adjust the DHCP client.

That didn't work.
But after trying to do modprobe ipw2100 and iwconfig eth0. I did dmesg.
it said that the firmware had failed to load.
I went to ipw2100.sourceforge.net
and tried the manual install they had -- didn't work,
There is a lot of differences in the directories where the manual install copies things to and where portage sends things too.
is there any way to load the firmwares? or something like that.
or is there a bug in the firmware? |

Have you enabled all the kernel options properly. CONFIG_FW_LOADER and hotplug support
Also can you post the dmesg error and lspci/lshw output. |

Your firmware is failing to load.
Check the following
1. Kernel Options. make sure you have these enabled in the kernel \.
(CONFIG_FW_LOADER)
| Code: |
Device Drivers ->
Generic Driver Options ->
<*> Hotplug firmware loading support
|
| Code: |
Device Drivers ->
Networking support ->
Wireless LAN (non-hamradio) ->
[*] Wireless LAN drivers (non-hamradio) & Wireless Extensions
|
| Code: |
Cryptographic options ->
<M> ARC4 cipher algorithm
<M> Michael MIC keyed digest algorithm
<M> CRC32c CRC algorithm |
If any of the above is not enabled recompile the kernel (preferably start with a clean one) and reboot into the new kernel.
2. firmware file
/usr/lib/hotplug/firmware/ipw2100-1.3.fw exists and is world readable.
3. You dont need ndiswrapper. Make sure that ndiswrapper is not set to autoload (comment it out in /etc/modules.autoload.d/kernel-2.6), run modules-update and reboot if it is loading automatically at boot.
4. If nothing above works remove the ipw2100 from /etc/modules.autoload.d/kernel-2.6 and try loading it manually after the bootup. |

Load a Module
Unload a Module | Code: | | modprobe -r ipw2100 |
Obviously you must be root to run the commands
the file | Code: | | /etc/modules.autoload.d/kernel-2.6 |
has the list of modules loaded at boot |

I am using gentoo-dev-sources
kernel 2.6.11-r4 and the hotplug option is not there.
| Quote: |
[*] Select only drivers that dont need compile time external firmware
[*] Prevent firmware from being built
--- Hotplug firmware loading support
|
Do I have to deselect the first two options to get a [ ] for the Hotplug option?
Also in terms of /usr/lib/hotplug/firmware/ipw2100-1.3.fw
I do not seem to have the /usr/lib/hotplug directory.
And this is my modules.autoload.d/kernel-2.6 file.
| Quote: |
# /etc/modules.autoload.d/kernel-2.6: kernel modules to load when system boots.
# $Header: /home/cvsroot/gentoo-src/rc-scripts/etc/modules.autoload.d/kernel-2.6,v 1.1 2003/07/16 18:13:45 azarah Exp $
#
# Note that this file is for 2.6 kernels.
#
# Add the names of modules that you'd like to load when the system
# starts into this file, one per line. Comments begin with # and
# are ignored. Read man modules.autoload for additional details.
# For example:
# 3c59x
|
so what do I do |

It is enabled by a dependency. which means that you have selected some component which requires hotplug support. So you cannot disable hotplug unless you remove the dependent application. Just to be sure
| Code: | | cat /usr/src/liux/.config|grep FW_LOADER |
should give
| Quote: | | I do not seem to have the /usr/lib/hotplug directory. |
you have not installed hotplug.
Download firmware image from here http://ipw2100.sourceforge.net/firmware.php?i_agree_to_the_license=yes&f=ipw2100-fw-1.3.tgz and extract all the files in the /usr/lib/hotplug/firmware/ directory
Once you have recompiled the kernel do
and then load the module
if it loads properly add on a separate line in /etc/modules.autoload.d/kernel-2.6
you also need to create a new network connection eth1
| Code: | cd /etc/init.d
ln -s net.eth0 net.eth1
rc-update add net.eth1 default
|
and also update |

i did all that,
I booted into kernel 2.6.9 r4 kernel and did all that.
Untarred my firmware file into the specified directory. but it didnt work. Did a dmesg and found that it was looking for the 1.2 version of the firmware and it looked like even though I had updated ipw2100 it was still using an older version of it.
So I untarred 1.2 version of the firmware in that directory and rebooted into my new kernel as a last resort , and suddenly
IT WORKED.
I don' t quite know which step made it work but it did work. so thats all good
thanks everyone |

| when you emerge ipw2100 it installs for the kernel which is pointed to by /usr/src/linux. If you boot into another kernel the new drivers wont be there. |

I've the same problem, when i do a iwconfig my eth1 doesnt appear...
I have an eth0 interface (wired lan) and i'm running a 2.6.10 kernel.
I've emerged everything you said in the posts and i'm running the modules automatically.
My dmesg only said
ipw2100: Intel(R) PRO/Wireless 2100 Network Driver, 1.0.5
ipw2100: Copyright(c) 2003-2004 Intel Corporation
hostap_crypt: registered algorith 'NULL'
ieee80211_crypt: registered algorith 'NULL'
(with other algorithms for hostap and ieee80211 that i'm autoloading)
The main problem is that in iwconfig the eth1 device doesn't appear, not even a wlan0 device. Whatother info can i provide?
Do i need the baselayout-1.11? my system is setted to only accept x86 packages.
When trying to load /etc/init.d/net.eth1 i get:
SIOCSIFADDR: No such device.
eth1: unknown interfafce: No such device.
I'm not using ndiswrapper because i don't how how to configure it or what to do with it.
BTW, i don't see my card in lspci, and it's working in windows.

Can you post the output of lspci /lshw .
| Quote: | | eth1: unknown interfafce: No such device. |
Are you able to load/unload ipw2100 module. Does lsmod show ipw2100 ?
| Quote: | | (with other algorithms for hostap and ieee80211 that i'm autoloading) |
The new versions of ipw2100 do not require hostap.
| Quote: | | I'm not using ndiswrapper because i don't how how to configure it or what to do with it. |
You dont need ndiswrapper. Just forget such a thing exists. |

lshw is another software like lspci but gives a more detailed output.
You dont have ipw2100 wireless card. You have ipw2200 which has different drivers. remove the ipw2100 drivers (atleast remove them from autloading and reboot) and do
| Code: | emerge ipw2200
emerge ipw2200-firmware
