Apology: I'm trying to pass a kidney stone and feeling a bit better
than lousy. Brain, logic, and spelling may not be too wonderful.
There are several ways to do this. I strongly suggest you stay with
DD-WRT v23 sp2. In order of my preferences:
1. Install a better antenna or reflector on the WHR-HP-G54 in the
back. Aiming more RF in the direction of the house, instead of
directions where it doesn't need to go will be a big help. For
reflectors see:
<http://www.freeantennas.com>
132 ft should work, but not if it has to go through walls. You might
also consider something else instead of the current client radio. To
see if a replacement might help, try walking around the house with a
known working laptop and determine the signal levels with Netstumbler.
If the laptop shows good signal, a different client radio is in order.
2. Relocate the existing WLIU2KG54AI with a longer USB cable to offer
better line of sight to the back WHR-HP-G54.
<http://www.buffalotech.com/products/wireless/wireless-g/wireless-g-keychain-usb-20-adapter-with-auto-installation/>
Officially, you can use a total of 5 meters of USB cables, but I've
gone much farther without problems. USB hubs and amplified USB cables
will also work. This USB radio has a very small low gain antenna in
order to fit inside the small package. Something with a bigger
antenna will work much better.
2. Setup a 2nd WHR-HP-G54 as a wireless client. Remove the existing
USB WLIU2KG54AI and run a CAT5 cable to the new WHR-HP-G54.
3. Setup a 2nd WHR-HP-G54 as a WDS bridge somewhere in the house. It
would need good line of sight to both the back router and the client
computer. With WDS, the new WHR-HP-G54 will act as both a bridge to
the back radio, and as an access point for client connections. In
effect, it's a repeater and a client at the same time.
However, with WDS and all repeaters, there is a 50% maximum speed
reduction for all wireless connections to the 2nd WHR-HP-G54. If you
run CAT5 from the computer instead of using the WLIU2KG54AI, you don't
have this loss. It's also important for this to be a 2nd WHR-HP-G54
with DD-WRT as this is the only combination that does WPA with WDS.
Other WDS implimentations only do WEP.
4. If you have a common phone line or power line between the two
buildings, think about using power line or phone line networking:

Also, you can piggyback 10baseT on a CATV coax cable.
<http://www.multilet.com>
Is there a common coax cable between buildings?
5. Setup the WHR-HP-G54 as a repeater. I hate repeaters.
6. Whatever else I forgot.

The setup varies depending on whether you configure the 2nd router as
a client ethernet bridge, WDS bridge, or simple repeater. Can I be
lazy and not go into all these setups? The WDS bridge is the most
complicated. See the DD-WRT wiki at:
<http://www.dd-wrt.com/wiki/index.php/Main_Page>
For WDS setup, see:
<http://www.dd-wrt.com/wiki/index.php/WDS_Linked_router_network>
<http://www.dd-wrt.com/wiki/index.php/WDS_Point_To_Point_%28P2P%29>
For client mode, see:
<http://www.dd-wrt.com/wiki/index.php/Client_Mode_Wireless>
etc...

Close. Try:
WLI-U2-KG54-AI

Yep. The number of walls and construction that the signal needs to
penetrate would be helpful. Also if there is anything in the window
that might cause problems (metal screening, aluminized mylar heat
refelctors, metal glass pane frames, etc). In general, I like to see
numbers, not descriptions. I would never have guessed your problem or
setup from the original posting. More generally:
1. What are you trying to accomplish?
2. What do you have to work with?

Good.

Oh, now you mention 3 walls. At 132 ft, I don't think you have a
chance to make this work directly. A repeater or 2nd WHR-HP-G54 will
probably necessary. However, I would still run some experiments to
see if a better client radio or better antennas will work.
Now, I'm going to roll over and play dead for a while.
