Laptop fails to connect to broadband router

I have a very simply plain-vanilla DSL set up at home. The DSL modem
plugs into the WAN socket of my wireless router and one of the 4 open
ports from the router connects to the Ethernet adapter endpoint on my
desktop computer.

With this setup I am able to access the Internet from my desktop
computer.

My laptop on the other hand isn't connecting properly to the router.
It says its connected to my wireless network (signal strength is
*excellent* and all that) but when I try to repair the connection the
"Renewing your IP address" activity either fails or goes on non-stop.
Trying

ipconfig /renew *wireless*

on the command prompt times out after a while saying "Unable to contact
DHCP server".
I also tried everything like ipconfig /flushdns, ipconfig /release etc
(followed by ipconfig /renew) to no avail.

Is there anything obvious I am missing?

The funny thing is when I configured the router (on my desktop using
http://IP_addr), even though I have a DSL connection at home I actually
had to set the connection mode to
Cable Modem under the router configuration to get the internet
connection to work. Leaving it as DSL doesn't work! Doh! The
broadband router support guy tells me that you just have to perform
some trial & error to choose the correct connection mode.

Here are some details from ipconfig /all on my laptop:

Autoconfiguration IP: 169.254.197.191
Subnet mask: 255.255.0.0
Gateway: <blank>

Hi
That IP that you get means that the Laptop can not connect to the DHCP
server on the Router and get an IP.
May be this can Help.
