nl80211 not found

Chanthearith HUON — 2008-12-01T21:25:17

Hello everyone, I recently installed command "iw" in order to use mesh capability in my wireless card. iw itself and its required library were installed successfully. But whenever I run the command "iw", this message appears "nl80211 not found." My linux is ubuntu 8.10 Intrepid Ibex with kernel 2.6.27 My wireless card: Pro/wireless 2200BG Network connection with ipw2200 driver. Can you give me some suggestions? Thank very much in advance.

[PATCH] iwlwifi: disable AP mode

Johannes Berg — 2008-12-01T17:50:27

iwlwifi does not support AP mode in any way. For one, it doesn't even buffer multicast/broadcast frames properly. We didn't allow zd1211rw AP mode to be enabled without this, so iwlwifi shouldn't be allowed to advertise AP mode either. It also doesn't work at all, it doesn't even answer to probe requests, I'm guessing the packet injection code was disabled again.

Hello I'm using the latest revision of compat wireless on a Debian Lenny with a 2.6.27.7 kernel downloaded from kernel.org. uname -ra Linux notebook 2.6.27.7 #1 SMP Thu Nov 27 15:12:29 ARST 2008 i686 GNU/Linux My notebook is fabricated in Argentina by Banghó. It has a rtl8187 usb wireless card. lsusb | grep Realtek Bus 001 Device 003: ID 0bda:8187 Realtek Semiconductor Corp.

I've search in the syslogs, messages and daemon.log and I can't find anything unusual. At least form me. When the connection stops I've to reload the driver with rmmod rtl8187 modprobe rtl8187 I'm a little far from de AP but it becames stable at 11Mb/s and it only falls with the bit torrent client.

iwlwifi - rfkill only works if the interface is up

Helmut Schaa — 2008-12-01T12:11:17

Hi, Since the patch "iwlwifi: delay firmware loading from pci_probe to network interface open" was merged, the driver's killswitch does not work anymore when the interface is down. The patch comment contains two arguments for that behaviour: 1) ... Because kernel initializes network devices subsystem before hard disk and SATA subsystem, it is impossible to get the firmware image from hard disk in the PCI probe handler. ... 2) For better power saving ... The current driver behavior is as follows: - iwl_pci_probe initializes the driver but disables the device, at this point changing the killswitch state will not be noticed by the driver and thus the killswitch state in sysfs will not reflect the real state - iwl_mac_start (which is called when at least one interface goes up) starts the device and loads the firmware if the killswitch is disabled. Otherwise the driver will just enable the interrupts and allows the interface to go up. However, if the device fires the interrupt CSR_INT_BIT_RF_KIL

This patch is based on Kalle's initial RFC patches on dynamic power save. Since ath9k/ath5k,stlc45xx and b43 need the driver to send the null frame, it is appropriate to do it from mac80211.

Ivo van Doorn — 2008-11-30T16:19:31

IV and EIV belong to eachother and don't require 2 seperate fields. Instead they can logically be merged into a single array with size 2. With this approach we can simplify the code in rt2x00crypto.c by using a single memcpy() when copying the iv/eiv data. Additionally we can move some code out of if-statements because the if-statement would always be true.
