Laptop can't acquire network address

Hi - I'm trying to hook up my lap top and my desktop - my desktop is wired to a linksys router, and the laptop is supposed to get on wirelessly.  However it can't get past the "Acquiring network address" stage.  I am trying to use WPA Pre-shared key.  I ran ipconfig on my desktop and my laptop.  The desktop has a subnet mask of and default gateway of  My lap top has a subnet mask of and just shows a blank on Default Gateway.  This is while it is trying to acquire the network address.

Anyhelp getting this to work would be greatly appreciated.  Thanks.

So your desktop is working but laptop is not, assuming you have Windows XP.  There could be many reasons for this behaviour, will try to address few of them.

Did you try to repair the Wireless connection, it is Support Tab of Wireless properties page, click on the repair and see if it helps.

If not, can you verify the WPA Pre-shared key, enter it again on the router and laptop, run the Network wizard again and see if resolves the issue.

If it still doesn't resolve the issue, follow the troubleshooting steps listed in following articles and post your results;

If the problem is still not fixed, if you have ehternet port on your laptop, try to connect it directly with the network and see if get an IP Address.

If it doesn't with wire (or you tried all above steps but still are able to connect without IP Address), follow the instructions in following article and post your results;

Hi.  Thanks naveedb.  It seems I might have had the preshared key slightly different on both computers.  The problem is solved now.  I'm surprised the laptop didn't just tell me the keys didn't match instead of getting locked up like that.  Anyway it seems to be working now so thanks.
It won't tell you that the key is wrong, but rather just deny you access. Makes it harder for the average user to guess that way.
Glad it worked.  As masnrock mentioned, it is a security measure in new protocols to counter brute force attacks, since brute force attacks depend on keep trying different keys untill they get access, by accepting any key and not giving an error message, it makes brute force attacks very difficult to work.
