hi a have a really strange network problem ...

i got a gentoo wireless-router with hostapd set up

everything went fine till i changed from x86 to x86_64, then the problem occurred

Router-IP : XXX.XXX.XXX.254 static configured
running dhcpd

I can connect with client1 to the router, get an ip and surf the internet

as soon as i connect client2 to the router, the connection on client1 breaks down
but is working beautiful on client2 8O

then
- i cant ping client1 from client2
- i cant ping the router from client1
- the wireless connection on client1 shows up as established
(no errors in the logs of the router or of then client)
- dhcpd is serving different ips to the clients
- there is a "pyhsical" connection from client1 to the router
(as i see arp requests with tcpdump on the router, when i ping something)

if i disconnect client2 from wlan, and reconnect client1
(reset, as it never was down)
everything is fine on client1 and vice versa

can someone point me into the right direction?
as i really dont know where the problem could be ...

i tracked down the problem to hostapd,

if i use wpa, i am unable to connect to the AP with more then one client,
(no problems if i use no encryption or wep)
thats really stranged, because i had it running before a migrated to 64bit

and it leaves hostapd rather useless :(

for now i use wep and tunnel all connections through openvpn,
till i find the root-cause and a solution :cry:
