Dotaz: Zprovozneni wifi Intel PRO/Wireless 2200BG

[Dave]

Pekny den,

snazim se o $SUBJ pod Linuxem (LFS-6.0, jadro 2.6.11.10, notebook Fujitsu Siemens lifebook e8010). Stahnul a nainstaloval jsem si firmware (ipw2200-fw-2.3) a ipw2200-1.0.4. Po zavedeni modulu:

Module                  Size  Used by
ipw2200               167688  0 
ieee80211              42948  1 ipw2200
ieee80211_crypt_ccmp    6656  0

ipw2200,ieee80211,ieee80211_crypt_ccmp,ieee80211_crypt_tkip,ieee80211_crypt_wep

ovsem dmesg vypise chybu:

ieee80211_crypt: registered algorithm 'NULL'
ieee80211_crypt: registered algorithm 'WEP'
ieee80211_crypt: registered algorithm 'TKIP'
ieee80211_crypt: registered algorithm 'CCMP'

Problem je, ze zminovany soubor ipw-2.3-boot.fw je na svem miste (/usr/lib/hotplug/firmware/). Kde tedy muze byt zakopany pes?

Máš zapnutý hotplug?

nevím, jestli to pomůže, ale hned pod downloadem ovladačů jsem našel toto:

Issues
Firmware files fail to load even if installed
In some kernel configurations (users have most frequently reported the problem only with 2.6.9), the default timeout value for the hotplug subsystem is too low. You may have this problem if you see the following in your kernel log (via dmesg or /var/log/messages):

ipw2200: Intel(R) PRO/Wireless 2200/2915 Network Driver, 1.0.1
ipw2200: Copyright(c) 2003-2004 Intel Corporation
ipw2200: Detected Intel PRO/Wireless 2200BG Network Connection
ipw2200: ipw-2.2-boot.fw load failed: Reason -2
ipw2200: Unable to load firmware: 0xFFFFFFFE
ipw2200: failed to register network device
ipw2200: probe of 0000:00:0b.0 failed with error -5

To work around this, you can increase the default timeout value:

echo 100 > /sys/class/firmware/timeout

and then reload the ipw2200 module. If this corrects your problem, you may wish to add the above line to your system startup scripts prior to the point at which the driver module would be loaded.

The other most common reason for getting the above error is that the firmware files are not installed in the correct location. Please see the INSTALL document for information on installing the firmware files.

Ze zkusenosti vim o dvou problemech. Jednak jiz zminovany problem s hotplugem (je potreba mit podporu pro nahravani firmware v jadre) a jednak jsem se jednou setkal s tim, ze se behem nektere verze prejmenovali ty soubory s firmwarem a tudiz v /usr/lib/hotplug/firmware byli sice spravne soubory, ale jmenovali se jinak.

ahoj,
pokud ti to porad nejede,mas zaply hotplug atd., zkus se podivat jestli ti hotplug firmware agent nehleda firmware v jinym adresari, napriklad ve slackware v /etc/hotplug/firmware.agent je defaultni cesta pro firmware /lib/firmware
