long start-up while wlan0 is enabled

Hi
I have Gentoo installed on my Powerbook for a while.
I had many problems as I'm not very experienced linux user. But I really =
like Gentoo.
One of my latest problem is long start-up while my wlan0 is active.
I've got 2 net cards (eth0 and wlan0). Both seem to work OK. Most of the =
time I use wlan0.
When system is booting and it's just about the login procedure there's a =
long delay. I just need to wait about 30 secs before I can log in. Similar =
problem is when I try to start X (startx command). And yet again it =
appears when I start the browser (seamonkey) - then I have to wait about a =
minute or longer. But when I disable the network (wlan0, eth0 is usually =
inactive) the problems disappears.
I've tried many ways to resolve it. I've emerged portmap thinking it can =
halp - no succes.
Can anybody halp?
Regards
JM
