Hi Folks I made considerable progress in my attempt to get the wifi client up and running. I found a simple network definition for wpasupplicant which would sufficiently describe the connection to my WRT54GH
STYX# cat /etc/wpa_supplicant.conf
ctrl_interface=/var/run/wpa_supplicant
update_config=1
network={
ssid="scoobly"
psk="xxxxxxxxxxx"
}
and here is the status
STYX# wpa_cli status
Selected interface 'wlan0'
bssid=00:25:9c:09:aa:12
ssid=scoobly
id=0
pairwise_cipher=CCMP
group_cipher=TKIP
key_mgmt=WPA2-PSK
wpa_state=COMPLETED
ip_address=192.168.217.100
The IP address is obtained using dhcp, so I assume the most basic
connectivity is there.
When I try top ping the AP then all I see on the interface is arp requests
STYX# tcpdump -i wlan0
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on wlan0, link-type EN10MB (Ethernet), capture size 65535 bytes
20:17:07.791504 ARP, Request who-has 192.168.217.1 tell 192.168.217.100,

20:17:08.793505 ARP, Request who-has 192.168.217.1 tell 192.168.217.100,

20:17:10.793533 ARP, Request who-has 192.168.217.1 tell 192.168.217.100,

20:17:11.795505 ARP, Request who-has 192.168.217.1 tell 192.168.217.100,
length 28
^C
4 packets captured
4 packets received by filter
0 packets dropped by kernel
So it appears that packets are passed at a certain moment.
If I disconnect and reassociate the following can be seen
STYX# tcpdump -i wlan0
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on wlan0, link-type EN10MB (Ethernet), capture size 65535 bytes

20:19:37.777122 ARP, Request who-has 192.168.217.100 tell 0.0.0.0, length 28
It appears that the connection comes up fine and dhcp takes place. Still
I cannot reach the AP.
When I enter the arp address manually I can see ICMP echos leaving
through wlan0, but no reply. It feels like the AP does not want to talk
to me.
Using my windoze laptop with the same AP I can ping without a problem :-(
Any ideas?
Thanks
Erich
