Hi,

I've set up my notebook with wlan on SuSE 9.3 and this wlan card works, because
if I boot the SuSE 9.3 on gateway with wlan, I have a connection.
When I start the SuSE 10.0 beta1, I can see the incoming ip packets on the
gateway with tcpdump, but I can't see any outgoing packet not even an arp packet.

here some data for better understanding:

Notebook:
SuSE9.3; IP 192.168.254.3/24

gateway:
SuSE 10.0 beta1; IP 192.168.254.1/24

when I ping from my notebook to the normal pc, I see the following tcpdump:
--snip--
gateway:~ # tcpdump -n -i wlan0
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on wlan0, link-type EN10MB (Ethernet), capture size 96 bytes
21:47:46.066313 arp who-has 192.168.254.1 tell 192.168.254.3
21:47:47.066152 arp who-has 192.168.254.1 tell 192.168.254.3
21:47:48.065989 arp who-has 192.168.254.1 tell 192.168.254.3
--snip--

then I added the MAC adresse manual to the arp table, because I thought there
may be some arp filters for security reason.
There are no icmp replay packets

There is no netfilter aktivated:

--snip--
gateway:~ # iptables -L
Chain INPUT (policy ACCEPT)
target     prot opt source               destination

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination
--snip--

I have tried it with the firmware from SuSE 9.3 (atmel-firmware-1.1) and with
the actual ones atmel-firmware-1.3

I will add the yast2 logs, hwinfo and dmesg, maybe it helps you.

I don't know what I can do anymore
