Can't get a wireless internet connection with a F@st 3464 modem

I'm having trouble getting access to the internet with my ArchLinux laptop and a F@st 3464 router via wireless (WEP). On the other hand, a winxp laptop and the n900 running maemo 5 have no problem to problem to get an internet connection.

My ArchLinux laptop is configured to connect to my home wireless network:

# /etc/rc.conf - Main Configuration for Arch Linux
#
[...]
wlan_eth1="eth1 essid MyWifi key s:XXXXXXXXXXX"
eth1="dhcp"
INTERFACES=(eth1)
gateway="default gw 192.168.0.1"
ROUTES=(!gateway)
[...]
 
DAEMONS=(slim syslog-ng network ntpdate netfs crond cpufreq ntpd @alsa @hal @laptop-mode)
### END /etc/rc.conf ###

This works fine.

But now in this other place, there's a F@st 3464 modem/router which is giving me headaches:

$ iwlist scanning
lo        Interface doesn't support scanning.

eth0      Interface doesn't support scanning.

eth1      Scan completed :
          Cell 01 - Address: 00:19:70:29:89:54

The router ip is 192.168.1.1, and subnet mask is 255.255.255.0
Dhcp server is active.
Now I try to configure a new wireless connection manually:

$ sudo iwconfig eth1 essid MyOtherWifi key s:XXXXXXXXX
$ iwconfig
lo        no wireless extensions.

eth0      no wireless extensions.

eth1      IEEE 802.11g  ESSID:"MyOtherWifi"  
          Mode:Managed  Frequency:2.412 GHz  Access Point: 00:19:70:29:89:54

          Retry limit:7   RTS thr:off   Fragment thr:off
          Power Management:off

          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:98

So far so good. I can see on the F@st 3464 router that the laptop is connected (its mac address is listed).

What the heck? I seem to have gotten the wished IP, why can't I connect?

Out of ideas, I try via a dhcp request:

$ sudo dhcpcd -d -t 140 eth1
Password: 
dhcpcd: version 5.2.1 starting
dhcpcd: eth1: executing `/usr/lib/dhcpcd/dhcpcd-run-hooks', reason PREINIT

Any suggestions? (I guess that this must be something stupid, but I'm not knowledgeable enough to have a feeling of what's wrong).
