wifi not working

[cubo]

hi,
on my thinkpad T60 i'm using updated opensuse 11.0 with KDE4.1 from obs-KDE4:factory repos and madwifi driver from madwifi.org. I can't get my wireless card working properly. I was trying several ways but with no luck.

1)networkmanager - can't manage wireless connections using knetworkmanager - i don't see any networks (there are no scan results), when added essid manually (and other options) knetwrokmanager creates profile but on click nothing happens

from /var/log/NetworkManager
<info> ath0: driver does not support SSID scans (scan_capa 0x00).
<WARN> real_act_stage2_config(): Activation (ath0/wireless): couldn't send wireless configuration to the supplicant.

2)iwconfig - i'm able to set up connection and succesfully connect but after some time my connection is dropped down. The txpower is automatically falling to 8dBm so i need to manually set up the txpower to 16/17dbm (heh..sometimes works with value 16 else 17).

some info:

hi,
i have installed openSUSE 11.0 on thinkpad R60 (intel 3945abg - driver iwl3945) with gnome. Wireless with gnome nm-applet was working until a have fully updated my system. After restart i found the same problems as described above... so answer to question 1) the problem is in wpa_supplicant. When i exec " wpa_supplicant -Dwext -iath0 -c/etc/wpa_supplicant/wpa_supplicant.conf -u" my knetworkmanager is able to scan networks and succesfully connect to any network (works for gnome nm-applet too).

How can i fix this in some clever way -
is it problem of dbus (as describes Networkmanager/dbus/wpa_supplicant )?

still have problem with txpower (for both cards, intel and atheros too, is falling down to 8dbm automatically

thanks
