associated to AP (WEP mode) && no IP addr via DHCP

[Matthias Apitz]

Hello,

I'm going frequently to a Greek restaurant in my town to have dinner
there or some red wine, and reading stuff;

the owner of the restaurant has a Wifi zone and gave me, as its best
client, the WEP-key to connect to Internet; the problem is that he does
not have the admin password of the AP (some else configured it) and so I
can't have a look into the config of the AP;

my /etc/wpa_supplicant.conf for the AP is:

# Restaurante Odyssey (2007-11-18)
#
network={
        ssid="ConnectionPoint"
        scan_ssid=0
        key_mgmt=NONE
        wep_tx_keyidx=0
        wep_key0=xxxxxxxxxxxxxxxxxxxxxx
}

and the interface associates fine:

# ifconfig ath0
ath0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
	ether 00:15:af:b2:ae:e6
	inet 0.0.0.0 netmask 0xff000000 broadcast 255.255.255.255
	media: IEEE 802.11 Wireless Ethernet autoselect (OFDM/36Mbps)
	status: associated
	ssid ConnectionPoint channel 11 (2462 Mhz 11g) bssid 00:01:e3:0e:97:99
	authmode OPEN privacy ON deftxkey 1 wepkey 1:104-bit txpower 31.5
	bmiss 7 scanvalid 60 protmode CTS burst roaming MANUAL

but a DHCP request does not give me any IP addr; with 

# tcpdump -n -i ath0 

it says:

19:01:01.603869 IP 0.0.0.0.68 > 255.255.255.255.67: BOOTP/DHCP, Request from 00:15:af:b2:ae:e6, length 300

this situation is already for monthes and I gave up and always use UMTS
if I want connect to Internet; until yesterday I was thinking in some
kind of MAC addr filter in the AP, but ....

yesterday I was there with a friend who has a Nokia mobile E51 device; I
gave him the key, he associated like me and got in the next second IP,
DNS and all was fine;

what is that for a problem? it is not ath0 related because my other
laptop with iwi0 does not get IP either;

what can I provide as information to nail this down?

Thx
