Unable to obtain IP

I have this problem with certain networks where I can't obtain an IP address. I'm using wicd-client, brcm80211

Network controller: Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller (rev 01)

A strange workaround that I use involves using airodump-ng. Does anyone know what could be causing this? I know the network is fine since I can connect to it when I'm using another laptop. This happens on an open network and one with WEP.

Re: Unable to obtain IP

Try increasing your DHCP timeout, sometimes works if for some reason the reply isn't coming back fast enough. Still a bug, but at least that way you get connectivity.

Re: Unable to obtain IP

How exactly would I do that? Other sites are telling me to edit /etc/conf.d/net, but I don't have this file.

Edit: I think I might have found it, is it /etc/conf.d/dhcpcd then I just add DHCPCD_ARGS="-t #"

Re: Unable to obtain IP

Although I added -t 0 to it, it doesn't wait forever like the man pages said it would. I'm still having trouble obtaining an IP.

Re: Unable to obtain IP

Same here, DHCP times out at wireless card (lan works, I'm just installing gnome ), static ip (with wireless, didnt tested with lan) doesnt work too.
Wlan connection is successfull, thats what wpa_supplicant in debug mode and iwconfig says.

edit: I may even scan with iwlist, so wireless driver seems to work fine, but i just cant get an ip
