Hi... i have a problem with my wifi-card. I don't know why the system do so, i have two ways of problem.

1) When i start the system, my gentoo trys to use dhcp for configuring wlan iface. It scans for wifi APs, and find some. But only protected. But later, in a few sec. it switch off the interface. (wlan0 down). So after it, when i try to connect to my AP, i try to scan for nets, getting if-ace up, and do the #iwlist wlan0 scan, it tells me "no results".. I don't know why ?

Code:
wlan0     IEEE 802.11bg  ESSID:"" 
          Mode:Managed  Frequency:2.412 GHz  Access Point: Not-Associated   
          Tx-Power=off   
          Retry min limit:7   RTS thr:off   Fragment thr=2352 B   
          Encryption key:off
          Power Management:off
          Link Quality:0  Signal level:0  Noise level:0
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0


Later, i try to do this connection manually..and when i do
#iwconfig wlan0 essid "dlink" or #iwconfig wlan0 ap SOME_MAC it just do...nothing... only changed the ESSID: to

Code:
wlan0     IEEE 802.11bg  ESSID:"dlink"


I even tried to do #iwconfig wlan0 txpower 10 (or 20), and #iwconfig wlan0 essid "dlink" ap SOME_MAC but i also had no connection...

Code:
wlan0     IEEE 802.11bg  ESSID:"dlink" 
          Mode:Managed  Frequency:2.412 GHz  Access Point: Not-Associated   
          Tx-Power=10 dBm


so... then i tried ndiswrapper with windows drivers....and it failed too.

2) When i modprobed ndiswrapper module, i have the following:

Code:
wlan0     IEEE 802.11g  ESSID:"default" 
          Mode:Auto  Frequency:2.437 GHz  Access Point: Not-Associated   
          Bit Rate:54 Mb/s   Tx-Power:20 dBm   Sensitivity=-121 dBm 
          RTS thr=2347 B   Fragment thr=2346 B   
          Encryption key:off
          Power Management:off
          Link Quality:0  Signal level:0  Noise level:0
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0


But the scan still gives me no results. I did all the commands i listed before for manual connection, but there what i had...

Code:
wlan0     IEEE 802.11g  ESSID:"default" 
          Mode:Auto  Frequency:2.437 GHz  Access Point: Not-Associated   
          Bit Rate:54 Mb/s   Tx-Power:-2147483648 dBm   Sensitivity=-121 dBm 
          RTS thr=2347 B   Fragment thr=2346 B


I tried to change mode, power, anything....it failed... So any idea what it can be ?

Notes: By the way, the last RT61's RFKILL event i suspect, is a consequence of module-remove procedure. (but i can mistake)

Not sure if this applies to 2.6.29, but please try the following patch:

Ok...seems like i've partially done with problem. So, i excluded rfkill support from kernel (but i think this is not a clue...) and rebuild it. So, i have the problem stand still.. Then i removed this link @net.wlan0 from net.lo script that starts all network devices in gentoo, so the system shouldn't do any influence on my card. And after reboot i have a working card.. Yeah, great! But, iwlist scan gives me only 2 network, but when i scan from my laptop, it gives me over 10... And, my laptop placed far from the window, where the signal to this networks is most! My G510 is placed on a shelf at the bottom of the window... So, i suspect some system incompatibilities to detect that networks. where can i look for ? please help
