 Posted: Wed Jul 20, 2005 6:58 am Post subject: Intel PRO/Wireless (ipw2200): Can't get wireless to work |
 |
|
(This has been moved from thread "Wireless just won't go.")
I've got an ACER Travelmate 4101WLMi on which I recently installed Gentoo. However, I can't get my ipw2200-based network card to work. Here are some details:
Modules loaded:
ipw2200
ieee80211
ieee80211_crypt
ieee80211_crypt_wep
According to 'iwconfig' my interface with wireless extensions is 'eth1'. I've also got a wired interface on 'eth0' which is running fine. 'net.eth0' and 'net.eth1' are symlinks to 'net.lo' in /etc/init.d.
My /etc/conf.d/net contains:
# Stuff for wired eth0:
config_eth0=( "192.168.2.189 netmask 255.255.255.0" )
routes_eth0=( "default gw 192.168.2.1" )
# Stuff for wireless eth1 (ipw2200):
config_eth1=( "192.168.2.188 netmask 255.255.255.0" )
routes_eth1=( "default gw 192.168.2.1" )
modules=( "iwconfig" )
essid_eth1="TANGO"
key_TANGO="xxxx-xxxx-xxxx-xxxx-xxxx-xxxx-xx"
preferred_aps=( "TANGO" )
I've set RC_VERBOSE="yes" in /etc/conf.d/rc. When doing a "/etc/init.d/net.eth1 start" I get following output:
* Starting eth1
* Loading networking modules for eth1
* modules: apipa iwconfig essidnet iptunnel ifconfig
* iwconfig provides wireless
* ifconfig provides interface
* Configuring wireless network for eth1
* Connecting to "TANGO" (WEP enabled - open) ... [!!]
* Failed to configure wireless for eth1 [!!]
The failure message appears after aprox. 8 to 10 seconds. Using Ubuntu it works fine - however, I noticed that in Ubuntu the wireless i/f is 'eth0' and the wired i/f is 'eth1', so just vice versa as in Gentoo.
Any hint or advice is very much appreciated!
TIA

Can you do and paste the results?
The obvious error is that it doesn't 'see' the AP... |

Yep, here we go:
| Code: | lo Interface doesn't support scanning.
eth0 Interface doesn't support scanning.
dummy0 Interface doesn't support scanning.
eth1 No scan result |
BTW, when I do a "rmmod ipw2200 && modprobe ipw2200" dmesg shows following strange entries:
| Code: | ipw2200: Intel(R) PRO/Wireless 2200/2915 Network Driver, 1.0.3
ipw2200: Copyright(c) 2003-2004 Intel Corporation
ipw2200: Detected Intel PRO/Wireless 2200BG Network Connection
ipw2200: Radio Frequency Kill Switch is On:
Kill switch must be turned off for wireless networking to work.
ipw2200: No space for Tx
ipw2200: failed to send RTS_THRESHOLD command
ipw2200: No space for Tx
ipw2200: failed to send FRAG_THRESHOLD command
ipw2200: No space for Tx
ipw2200: failed to send POWER_MODE command
ipw2200: No space for Tx
ipw2200: failed to send TX_POWER command
ipw2200: No space for Tx
ipw2200: failed to send RTS_THRESHOLD command
ipw2200: No space for Tx
ipw2200: failed to send FRAG_THRESHOLD command
ipw2200: No space for Tx
ipw2200: failed to send POWER_MODE command
ipw2200: No space for Tx
ipw2200: failed to send TX_POWER command |
This doesn't look too healthy.  What's going wrong here?

I might have identified the problem - your "wireless radio" button on the computer seems to be in a "off" state...
There two lines seem to imply that: | Code: | ipw2200: Radio Frequency Kill Switch is On:
Kill switch must be turned off for wireless networking to work. |
Try pressing it and then run again.
(EDIT) NOTE: I have the same in mine when the wireless Kill Switch is On (or the les is not lit in my case, i have a ipw2200 as well)

Which version of ipw2200 are you using?
Also, there's two scripts included with ipw2200 to load and unload the modules in the correct order. The scripts are meant to be run from within the directory where the modules are built. I've modified them to fit with where gentoo installs the modules.
/usr/local/bin/ipw2200unload: | Code: | #!/bin/sh
if [ `whoami` != "root" ]; then
echo "You must be root to run this script."
return
fi
unset UNLOADED
for i in ipw2200 ieee80211{,_crypt{_{tkip,ccmp,wep},}}; do
if lsmod | grep -q $i; then
UNLOADED="${UNLOADED}${i} "
/sbin/rmmod $i
fi
done
if [ -z "${UNLOADED}" ]; then
echo "No modules unloaded."
else
echo "Unloaded: $UNLOADED"
fi |
/usr/local/bin/ipw2200load: | Code: | #!/bin/sh
# Copyright (C) 2004-2005 Intel Corporation
MODULE=ipw2200
if [ `whoami` != "root" ]; then
echo "You must be root to run this script."
return
fi
. /usr/local/bin/ipw2200unload
unset LOADED
modulesdir="/lib/modules/`uname -r`/net/"
#modulesdir="/lib/modules/`uname -r`/net/ieee80211/"
function load_pre
{
for i in firmware_class; do
if ! (lsmod | grep -q $i) && \
! (modprobe $i > /dev/null 2>&1 && LOADED="${LOADED}${i} ") && \
! (grep -q request_firmware /proc/kallsyms); then
if [ ! -e /proc/kallsyms ]; then
echo "Could not be determine if firmware_class is already loaded."
echo "Attempting to load driver anyway..."
else
echo "Firmware capabilities not found. See INSTALL."
return 0
fi
fi
done
return 1
}
function load_modules
{
IPW_DEBUG=""
I_DEBUG=""
for i in ieee80211_crypt ieee80211_crypt_{wep,tkip,ccmp}; do
if [ -e "${modulesdir}/${i}.ko" ]; then
/sbin/modprobe ${i} && LOADED="${LOADED}${i} "
fi
done
for i in ieee80211; do
if [ -e "${modulesdir}/${i}.ko" ]; then
/sbin/modprobe ${i} ${I_DEBUG} && LOADED="${LOADED}${i} "
fi
done
if [ -z $1 ]; then
/sbin/modprobe ${MODULE} ${IPW_DEBUG} && LOADED="${LOADED}${MODULE} "
else
/sbin/modprobe ${MODULE} $@ && LOADED="${LOADED}${MODULE} "
fi
return 1
}
if ! load_pre && ! load_modules $@; then
if [ -z "${LOADED}" ]; then
echo "No modules loaded."
else
echo "Loaded: ${LOADED}"
fi
else
echo "Load failed."
fi |
If you're using ipw2200-1.0.4 or earlier leave the modulesdir line as it is. If you are using 1.0.5 or later comment out the modulesdir line and uncomment the other one.
Run ipw2200unload to unload all of the modules, then ipw2200load to load them in the correct order.
I've found it's sometimes necessary to unload the ipw firmware as well: | Code: | | rmmod firmware_class |

@elestedt:
I shortly pressed the "wireless lan" switch and ran "iwlist scan" which gave no difference. Then I pressed the switch a bit longer (for about two to three seconds), then I got:
| Code: | | bash_prompt # Disabling IRQ #10 |
on the screen and afterwards an "iwlist scan" shows:
| Code: | lo Interface doesn't support scanning.
eth0 Interface doesn't support scanning.
dummy0 Interface doesn't support scanning.
eth1 Interface doesn't support scanning : Input/output error |
Something seems to have changed but not for the better...

BTW, when booting from the Gentoo Minimal CD the card works, but only after issuing this command (as explained here: http://ipw2200.sourceforge.net/):
| Code: | | echo 100 > /sys/class/firmware/timeout |
It seems that everything is fine when using the hotplug system. Does this info help?

I just compared which modules we have loaded - and I have one loaded which you do not...
which is used by ipw2200.
have you installed net-wireless/ipw2200-firmware properly?
The only module in my modules.autoload.d/kernel-2.6 (relevant to ipw2200) is ipw2200 - the rest are loaded automatically. |

Module 'firmware_class' is indeed missing on my system. Is it supposed to be installed along with 'ipw2200-firmware'? I've got those installed:
| Code: | net-wireless/ipw2200-firmware-2.2
net-wireless/ipw2200-1.0.3 |
However, an "etcat -f ipw2200-firmware" doesn't show any 'firmware_class.o' module and I can't do a "modprobe firmware_class" either. I noticed this module when booting from the Gentoo CD and within Ubuntu.
Would this mean something is corrupt in my installation?

Actually that module *seems* to be part of the kernel - I don't know how I got it though... just went through the config but cannot find it.
equery gives this:
| Code: | # equery b firmware_class
[ Searching for file(s) firmware_class in *... ]
sys-kernel/gentoo-sources-2.6.12-r6 (/usr/src/linux-2.6.12-gentoo-r6/Documentation/firmware_class)
|
| Code: | /lib/modules/2.6.12-gentoo-r6/kernel/drivers/base:
total 12K
-rw-r--r-- 1 root root 11K Jul 19 19:15 firmware_class.ko
|
Hope that helps - i'll try to find the option...
One thing to try: have you enabled " Prevent firmware from being built" in the kernel? |

I've got this in Device Drivers -> Generic Driver Options:
| Code: | [ ] Select only drivers that don't need compile-time external firmware
[ ] Prevent firmware from being built
<*> Hotplug firmware loading support |

Now module 'firmware_class' is loaded (after I have set both a.m. Generic driver options and recompiled kernel plus modules), however, to no avail. The card is still not working, both before and after pressing the "wireless LAN" switch.

Sorry, I forgot to mention that I also changed the "Hotplug firmware loading support" option to be a module. Obviously, "firmware_class" is provided and needed by the hotplug system.

What do you get in dmesg and messages when loading and after you press the button?
Which kernel are you using?
Does the card work if you issue the echo command you mentoined earlier? |

I will answer later this evening as I'm now out.
Thanks anyway for your help and patience so far!

1) Kernel is: gentoo-sources-2.6.12-r4
2) Issuing the echo command would not help.
3) This is the output of dmesg after "modprobe ipw2200":
| Code: | ipw2200: Intel(R) PRO/Wireless 2200/2915 Network Driver, 1.0.3

4) This is "modprobe ipw2200" after pressing the "wireless lan" switch (and after "Disabling IRQ #10" has appeared on the screen):
| Code: | ipw2200: Intel(R) PRO/Wireless 2200/2915 Network Driver, 1.0.3

I Would do the following:
1. Purge ipw2200* from the system
2. Upgrade kernel (or at least recompile with: make && make modules_install) - gentoo-sources-2.6.12-r6 is stable
3. Install ipw again.
Probably won't do any difference - but it's worth a try? |

As a first step I unmerged ipw2200*. Funny enough, after I rebooted the modules "ipw2200" and "ieee80211*" are still there and being loaded! 
I've the impression that something on my system is plain wrong. Since I've just installed a fresh Gentoo a couple of days ago I'm considering just to start all over again...

Sounds like a reinstall could work...
But epgrading the kernel should be enough. |

Okay, upgraded to gentoo-sources-2.6.12-r6, however, same result: Wireless card doesn't work and the same strange error messages in dmesg. However, I know for sure that yesterday evening these error messages were not present although I already had this
| Code: | ipw2200: Radio Frequency Kill Switch is On:
Kill switch must be turned off for wireless networking to work. |
message.
If the hardware was broken the card wouldn't work from the Gentoo CD, so we can exclude that. I'm still thinking to do a re-install. However, this is by far not my first Gentoo installation (it's the first one on a notebook) and I can't see what should have gone wrong this time...

seems to be part of the driver - since I have this and my card works.
Many things seem to be able to go wrong in any number of ways... most of the errors I've had was due to bad USE-flags or optimizations.
I can tell you that gentoo-sources-2.6.12-r6 and ipw2200-1.0.3 and ipw2200-firmware-2.2 since that what I use... |

Maybe looking for acerhk module in portage will help a little. I know that there is support for additional keys in acer laptops.
This error about Radio switch is from HW - it shouldn't be driver issue.

Hi maystorm,
it has indeed to do with the radio on setting and your button on the front of your nice 4101WLMI 
I have the following in /etc/modules.d/ipw2200 | Code: | | options ipw2200 disable=1 led=1 |
After you entered this you have to run
Then you can remove the ipw2200 module and load it again with modprobe and look if you get the red led in the front already burning - try to start net.eth1 and if it does not work press the button and try it again ...
This should work ...
HTH
