Hi there.
I have just got a d link dwa 140 wirless N usb adapter for my pc running windows XP. i'm trying to connect to a d link dir 635 wireless N router which is connected to our cable modem. When i click connect using either the d link or winxp utility, the status remains on acquiring network address indefinitely, and packets are sent by not received. i have not put any security on the network for simplicity - hopefully try to get the internet working with no security and then go from there.
now, a few things that i've tried. I've tried setting the IP address manually and reserving that address on the router – it says that it's connected, but still no packets are being received, thus no internet. windows firewall is off on my computer, and i've just reinstalled windows and formatted, so there is no antivirus software. I have MAC address filtering on on the router, and the correct MAC address is entered.
ipconfig/all looks like this:

connection-specific DNS suffix:
description : d link dwa 140 rangebooster N usb adapter
physical address: 00-1E-8-B0-C8-68
autoconfiguration enabled: yes
ip addres: 0.0.0.0
subnet mask: 0.0.0.0
default gateway:
DHCP server:255.255.255.255

there are three other Mac running OS X 10.4.11 connected to this network, and they all receive internet perfectly.
i've tried uninstalling and reinstalled the adapter, and restarting wireless zero configuration.

this problem has stumped me quite a bit and any help would be greatly appreciated
