Wireless network mystery

I have a real mystery on my home LAN. I can set up the network just fine
without encryption - the client requests an address, everything happens
just right:

Aug 17 19:12:48 hydra dhcpd: DHCPDISCOVER from 00:30:bd:64:a8:c8 via eth0

Aug 17 19:12:49 hydra dhcpd: DHCPOFFER on 192.168.128.148 to
00:30:bd:64:a8:c8 via eth0

Aug 17 19:12:49 hydra dhcpd: if IN A hermes2.seiner.lan domain doesn't
exist add 300 IN A hermes2.seiner.lan 192.168.128.148 add 300 IN TXT
hermes2.seiner.lan "008a2b4599d19b6482f1b8cdcb1156ad19": success.

Aug 17 19:12:49 hydra dhcpd: delete IN PTR 148.128.168.192.in-addr.arpa.
add 300 IN PTR 148.128.168.192.in-addr.arpa. hermes2.seiner.lan: success.

Aug 17 19:12:50 hydra dhcpd: DHCPREQUEST for 192.168.128.148
(192.168.128.1) from 00:30:bd:64:a8:c8 via eth0

But as soon as I turn on encryption, the client stops receiving all
information, and here's what I get in the logs:

Aug 17 19:09:33 hydra dhcpd: DHCPDISCOVER from 00:30:bd:64:a8:c8 via eth0

Aug 17 19:09:34 hydra dhcpd: DHCPOFFER on 192.168.128.148 to
00:30:bd:64:a8:c8 via eth0

Aug 17 19:09:39 hydra dhcpd: DHCPDISCOVER from 00:30:bd:64:a8:c8 via eth0

Aug 17 19:09:39 hydra dhcpd: DHCPOFFER on 192.168.128.148 to
00:30:bd:64:a8:c8 via eth0

Aug 17 19:10:00 hydra dhcpd: DHCPDISCOVER from 00:30:bd:64:a8:c8 via eth0

Aug 17 19:10:00 hydra dhcpd: DHCPOFFER on 192.168.128.148 to
00:30:bd:64:a8:c8 via eth0

Aug 17 19:10:54 hydra dhcpd: DHCPDISCOVER from 00:30:bd:62:7e:29 via eth0

In other words, the client is sending packets, the server is receing them,
and responding. But the client acts as if it's not seeing any DHCP
servers at all (thus the multiple DHCPDISCOVER lines).

Any idea on where to begin figuring this out? I'm not really experienced
with wireless, so I'm a bit clueless here. I've always thought the
encryption is symmetrical, so if it works one way, it should work the
other way... No? What am I missing here?

Both systems are RH 8, the AP is a Belkin F5D6130 configured with
ap-config, and the client is a Belkin USB F5D6050, with the atmel drivers.

TIA,

Can't help directly, but are you sure your keys are the same case and you
have the same key selected on the AP and on the client? Same for ESSID?
