udvozletem,

mar regota kuzdok egy problemaval a wireless halozatomon.
adott egy d-link dwl-g520+-os halokartya a gepben es egy d-link di-614+ 
router adsl-el a masik vegeben. a halokartyat acx111-es driver mozgatja, 
amit a (link!) alapjan lottem be (forgattam uj drivert). a halozat 
wep-pel van vedve.
a problema az hogy szamomra megmagyarazhatatlan okokbol neha gondol 
egyet a halozat es megszakad hosszabb rovidebb idore.
neten kutatva osszehoztam egy "scriptet" ami igy nez ki:

#!/bin/bash
cd /lib/firmware/$(uname -r)/acx/default
mv tiacx111c16 tiacx111c16.bak
ln -s ../1.2.0.30/tiacx111c16
invoke-rc.d networking stop
rmmod acx
modprobe acx
invoke-rc.d networking start

erre van hogy indul a net, gondolom azert is mert ujrainditja a halozati 
konfot. probalkoztam invoke-rc.d networking restart paranccsal aminek ez 
volt a kimenete:

root at linux:/home/gergely# invoke-rc.d networking restart

egyreszt nem ertem mit akar ezzel mondani, masreszt meg ami gondolom 
nyilvanvalo hogy nem akar netet csni :)
minekozben futott egy iwevent is:

18:15:24.443096   wlan0    New Access Point/Cell address:Not-Associated

18:15:31.055526   wlan0    New Access Point/Cell address:Not-Associated

es folyamatosan ezeket a "Not-Associated"  sorokat dobalja nekem.
logban is televagyok szamomra erthetetlen uzenetekkel:

nem is tudom mit kene meg irni hogy pontosabb legyek, azert meg alljon 
itt hogy a rendszer egy dapper napi frissitessel, es meg van egy laptop 
amivel linux es win alol is siman fel tudok csatlakozni a halozatra 
akkor amikor ezzel a pc-vel nem, es meg egy "iwconfig wlan0" is:
(perpill nem csatlakozva a nethez:)

wlan0     IEEE 802.11b+/g+  ESSID:"Philcom"  Nickname:"acx v0.3.21"
          Mode:Managed  Frequency:2.442 GHz  Access Point: Not-Associated
          Bit Rate:54 Mb/s   Tx-Power=15 dBm   Sensitivity=1/3
          Retry min limit:7   RTS thr:off
          Power Management:off
          Link Quality=36/100  Signal level=10/100  Noise level=0/100
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:881  Invalid misc:0   Missed beacon:0


es csatlakozva:

wlan0     IEEE 802.11b+/g+  ESSID:"Philcom"  Nickname:"acx v0.3.21"
          Mode:Managed  Frequency:2.442 GHz  Access Point: Not-Associated

          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0

a valaszokat elore is koszonom!
