dhcpcd kills wlan0


So i've been running my wireless card just perfectly under Slackware 9.0 for the last 6 months or so. This week I tried to upgrade to Slack 10 only to run into some major problems.

I'm using the linux-wlan-ng drivers for my prism2_usb card.

I issue all of the proper wlanctl-ng commands and can connect to a wireless access point. (for example):

$ modprobe prism2_usb prism2_doreset=1
$ wlanctl-ng wlan0 lnxreq_ifstate ifstate=enable
$ wlanctl-ng wlan0 lnxreq_autojoin ssid=linksys authtype=opensystem

If I then run iwconfig it shows me that i am connected to the access point.
Then I run:
$ dhcpcd wlan0

This much would run PERFECTLY under slack 9.
Now, this command gets an IP address, as I can see with `ifconfig`. HOWEVER, when I now issue an `iwconfig` command shows me that the wireless interface is now DISAPPEARED!! (WTF?!)

Though I have an IP, pinging the router does not work.

Any advice?

A brief update:

I realized that Kismet runs fine, and lets me see all of my neighbor's networks as usual. So I fear the main problem lies in dhcpcd.

All help appreciated.

Another update.
As I stated in another thread.. this, for some reason, works:

1. I bring up wirless interface
2. dhclient wlan0 (or whatever else). this fails with some error about the interface not being found.
3. dhcpcd wlan0 (etc..) should then work fine - gets an IP.

WHY does this work? i don't know...

I really hope there's a better way to do this.. but for now, this works for me.
