I'm trying to get WIFI working on a Fujitsu-Siemens Amilo M7400 laptop.
It doesn't work, and here are the details.
I'm using Linux kernel 2.4.22, with Debian testing. Dual boot to
Windows XP and everything works fine - it scans and finds the network
from my router. The wireless router is configured with no security.
The driver loads apparently fine:
# dldrconfig --info
Linuxant DriverLoader for Wireless LAN devices, version 1.54
Web configurator: listening on 127.0.0.1:18020
Current parameters: ("dldrconfig --info")
Wireless interface name: eth1
MAC address : 00:04:23:74:E0:30
Device instance: PCI-0000:02:06.0-8086:1043-8086:2527
Device driver : w70n51
Description : Intel(R) PRO/Wireless 7100 LAN Card Driver
Adapter model : PRO/Wireless LAN 2100 3B Mini PCI Adapter

I've tried with two versions of the Windows driver w70n51:
07/31/2003,184.108.40.206 (latest intel driver)
03/07/2003,220.127.116.11 (version currently installed when I reboot to Windows)
The wireless ethernet interface appears OK:
# iwconfig eth1
eth1 IEEE 802.11-DS ESSID:"" Nickname:"unknown"
Mode:Managed Channel:0 Bit Rate=11Mb/s
RTS thr=1600 B Fragment thr=0 B
Link Quality:1/1 Signal level:-98 dBm Noise level:-200 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0
At this point things stop working. If I scan for wireless connections,
it doesn't find any. Can you explain what exactly this message means -
does it mean iwlist failed to even connect to the hardware and scan,
or does it mean that it tried scanning but couldn't find anything?
# iwlist eth1 scan
eth1 Failed to read scan data : No data available
I tried configuring the eth1 channel and ESSID and doing "ifup eth1", but the
pump DHCP client never gets a reply to its requests.
In the BIOS I changed a setting to "Enable WIFI". This now means that under
Windows I don't have to press the Wifi button to turn on the connection -
the wifi LED on the laptop lights up as soon as Windows boots. Under
Linux it makes no difference.
Also, under Linux the wifi LED on the laptop has never lit up. I feel as
though the driver isn't initialising right - that the light should light up
when the wifi hardware is powered, before a connection is made.
Anyone have any suggestions? I'm desperate to pay my $20 as soon as this works ;)
