OK, an RF issue. The problem is that I can't tell from here whether
it's the BEFW11S4 or the WPC11. The only way to be sure is to test
each one individually. Invite someone over with a known working
laptop with wireless and have them test your BEFW11S4. Similarly,
take your laptop to the nearest free hot spot or place with a known
working wireless, and do some range testing. That should assign the
blame to one or the other.

Perhaps some aluminium foil backed fiberglass insulation in the walls?
How is the signal strength inside the room? Can you walk around the
room and keep the connection at excellent? If so, then it's possible
that the problem is in the walls. Move the access point temporarily
to some location where you have unobstructed line of sight. Take a
hike with your laptop. See how far you get. 100ft before it starts
to screw up is minimum acceptable. 300ft before you lose connection
is typical.

Leave the CTS/RTS flow control threshold along. With a fairly high
number, CTS/RTS flow control is turned off. That's what you want with
a small indoor system. If you were running the router outdoors, and
were in a location where you have a "hidden transmitter" type problem
(where multiple client radios cannot hear each other), then you might
consider enabling flow control. Otherwise, leave it off, which is the
default. Same with fragmentation limit, which is great for getting
though interference, but that's not the problem here.
Normally, I would say that it's not a software/driver issue. However,
I just had a miserable time with a Dlink DWL-G520vB1 PCI card on a W2K
SP4 system. It would work, but the range was about 5 ft from my known
working access point. I knew the card wasn't broken because I had
just removed it from a working machine as part of a system upgrade.
Eventually, I discovered that the latest driver 3.17 from the web pile
just didn't work. I removed it and installed the driver that came on
the cdrom in the box (1.0 ??) , and everything worked as expected.
I'm not sure what to suggest other than try different WPC11 drivers.
