Hi there, I've posted this message on the users mailing list but got no answer whatsoever. Please somebody give me at least some acknowledgement, this is all getting very frustrating ! I'm trying to use the HAL from Ticket 1192 <http://madwifi.org/ticket/1192> (both suggested snapshot and latest svn) on a Siemens Amilo Li2727 with Ubuntu 8.04, everything goes fine during compilation and installation however I'm unable to connect. iwconfig -> Access Point: Not-Associated iwlist ath0 scan -> ath0 No scan results athstats 1 -> input output altrate short long xretry crcerr crypt phyerr rssi rate 0 3265 0 0 0 0 0 0 0 0 0M 0 0 0 0 0 0 0 0 0 0 0M 0 4 0 0 0 0 0 0 0 0 0M athstats -> 3277 tx management frames 3277 tx frames with no ack marked Antenna profile: [1] tx 2 rx 0 [2] tx 1 rx 0 It looks like the card receives nothing at all. If everything being equal I reboot under Vista everything works fine. Does anyone here has an idea ? Thanks a lot!

Try monitor and master mode. In master mode, other stations should see the beacons sent by your card. -- Regards, Pavel Roskin |

Hi, which channel does your access point use? Perhaps you're using a channel greater than 11 and your card is restricted to channel from 1 to 11. I have the same problem here. Windows is able to access the channels 1 to 13 while Linux is only able to access channel 1 to 11.

Hi there, I've finally been able to solve my problem, thanks to the hints that I got from the list! Thanks a lot to everyone! As Pavel had correctly sensed, the problem (no transmission at all) was due to a software-only RF switch in the Siemens Amilo Li2727 that needs to be switched on before any transmission can occur. The problem and its solution are described on this page <http://madwifi.org/wiki/UserDocs/MiniPCI>, under paragraph "Fujistsu Siemens Amilo Li1718 with Atheros AR242x 802.11abg PCI-e (rev 01) ". The solution was to download and install the acerhk driver<http://cakey.de/acerhk/> and then add this line to /etc/modprobe.d/madwifi : install ath_pci /sbin/modprobe acerhk; echo on > /proc/driver/acerhk/wirelessled; /sbin/modprobe --ignore-install ath_pci and to /etc/modprobe.d/options : options acerhk autowlan=1 As an added bonus, this also lights up the orange wireless LED on the front of the laptop :-) As a side note, the ath0 interface is entirely managed by the /etc/network/interfaces config file (this is Ubuntu 7.10) . To allow this, I have the following lines in /etc/modprobe.d/options: options ath_pci autocreate=none and the /etc/network/interfaces entry looks like this: auto ath0 iface ath0 inet dhcp pre-up wlanconfig ath0 create wlandev wifi0 wlanmode sta post-down wlanconfig ath0 destroy wpa-driver wext wpa-key-mgmt WPA-PSK wpa-proto WPA2 wpa-ssid xxxxxxxx wpa-psk yyyyyyyyy I'm willing to post a detailed solution on the site if you feel it's worth it. Again thanks a lot to everyone !

Hi Christian. Thanks for the detailed feedback. > I'm willing to post a detailed solution on the site if you feel it's worth > it. Yes, please do so. I suggest to start a new wiki page somewhere under UserDocs and link to it from the UserDocs page. If you need help with this, feel free to contact me offlist. Bye, Mike |

Either that or you need to plug an antenna in. Matthew |
