Hey Mojo,
thankx for your answer! Here you are:
Linux secureweb 2.6.37-slitaz #2 SMP Sat May 21 19:25:28 CEST 2011 i686 GNU/Linux
00:0d.0 Ethernet controller: Atheros Communications Inc. AR2413 802.11bg NIC (rev 01)
wlan0 IEEE 802.11bg ESSID:off/any
Mode:Managed Access Point: Not-Associated Tx-Power=20 dBm
Retry long limit:7 RTS thr:off Fragment thr:off
Power Management:off
I think i tried desperate measures by setting up a value for the TX-Power :-)
But i noticed a very strange thing: I find wireless LANs in the neighbourhood, but not mine (and that is only 2,5 m away from me). And if i use another Linux Distro like OpenSuse or Ubuntu i have nearly a full signal for my router.... It looks like with slitaz my wlan-card has less power....
By the way, how can i set another password for the slitaz panel?
Thank you in advance!
