Very slow connection on wireless network

I am getting a very slow throughput on my wireless network and I'm
having other general issues with it.

My network consists of a desktop and a laptop. On my desktop computer
I have a wireless PCI card (Edimax Wireless LAN PCI Card EW-7126) with
an external antenna. The computer shares its wired connection to the
Internet. It is running Windows XP Pro.

On my laptop I have a wireless PCMCIA card (Edimax Wireless LAN
Cardbus Adapter EW-7106PC). The laptop is running Windows XP Home.

I don't use a Wireless Access Point, so the two computers connect to
each other in Adhoc mode.

I have installed the latest drivers from the manufacturer's Web site,
yet the wireless connection is very, very slow. On the laptop, when I
access the Internet, the speed doesn't get much higher than 2-3
kB/sec, even when the two machines are in the same room. Windows
reports both the signal quality and stregth to be excellent and the
connection speed is reported on both computers as 11MBs/sec.
Furthermore, if I try to transfer files much bigger than 100 KB
locally from one computer to the other, the file transfer cancels
before the file transfer is over.

How come I have such a slow throughput? What are the specific settings
I should have on my computers? Enabling or disabling WEP doesn't seem
to make much difference.

On another issue, on my laptop some network connections seem to be
bridged. Should I bridge connections on the desktop computer as well?
Right now on the desktop computer, in the Network Connections panel,
my Internet connection appears under Broadband, and it is Shared.
Under LAN or High-Speed Internet I've got Local Area Connection (the
HomePNA card that connects to the Internet) and the Wireless Network
Connection. Should I bridge the two latter?

Any assistance would be highly appreciated.

run something like NetPerSec this will show exact throughput
Just because you are running a 11Mbps doesnt mean that is what you will get,
through put will be about 5.5 - 6 at best

Sure but you must be talking about MEGAbits here. I just downloaded a
file over the wireless network and the file transferred at about 3
KILObytes per sec. Surely that's way too slow, right?! That's slower
than what I get with dial-up.

Entity Arthur Dent spoke thus:

One thing you can do is PING the other machine from both ends. This simply
sends a message that says "can you hear me now". A typical ping session
sends 20 requests and if you have 70% packet loss on either end your
throughput will be nil.

If you are running Windows bring up a DOS Terminal and type PING followed by
the IP# of the other end.

Mr. Dent,

In addition to the other suggest people have posted, you may want to
consider reflectivity. Wireless adapters transmit at extremely high
frequencies and can be influenced by hard smooth surfaces, such as windows
or mirrors. Try moving your laptop around to different locations to see if
you get better, clearer signal.
