iwn0 macht Stress und provoziert timeouts

Themenstarter #1
Hi,

ich habe hier in einem Dell E4300 eine Intel Centrino wlan karte die als iwn0 erkannt wird. Der WLAN Empfang ist extrem schlecht, aber er connected meistens. Allerdings müllt er /var/log/messages mit "Device timeout" zu.

Code:
wlan0: link state changed to DOWN
iwn0: device timeout
iwn0: iwn_read_firmware: ucode rev=0x08530501
iwn0: scan timeout
iwn0: iwn_read_firmware: ucode rev=0x08530501
wlan0: link state changed to UP
wlan0: link state changed to DOWN
iwn0: device timeout
iwn0: iwn_read_firmware: ucode rev=0x08530501
iwn0: scan timeout
iwn0: iwn_read_firmware: ucode rev=0x08530501
wlan0: link state changed to UP
wlan0: link state changed to DOWN
iwn0: device timeout
iwn0: iwn_read_firmware: ucode rev=0x08530501
iwn0: scan timeout
iwn0: iwn_read_firmware: ucode rev=0x08530501
wlan0: link state changed to UP
wlan0: link state changed to DOWN
wlan0: link state changed to UP

Totaler murks. Lädt der iwn Treiber Firmware code in die CPU des WLAN Controllers? Anscheinend panicked der. Ist das ein Defekt der Karte oder schickt der Treiber defekte Kommandos?

Welche FreeBSD Version nutzt du?
Allgemein wuerde ich sonst mal den Standard bei zickigen wlan Karten probieren und ht abstellen:
ifconfig wlan0 -ht
 
#5
Was ist denn dieses -ht für eine Option?
man ifconfig
Enable use of High Throughput (HT) when using 802.11n (default).
The 802.11n specification includes mechanisms for operation on
20MHz and 40MHz wide channels using different signalling mecha-
nisms than specified in 802.11b, 802.11g, and 802.11a. Stations
negotiate use of these facilities, termed HT20 and HT40, when
they associate. To disable all use of 802.11n use -ht. To dis-
able use of HT20 (e.g., to force only HT40 use) use -ht20. To
disable use of HT40 use -ht40.
