Download Speed Question

I have three XP computers connected in a home network to a Linksys WRT54GS
router through Linksys WUSB54G (ver 4) wireless adaptors. For each computer
I downloaded the same 60 MB file from Garmin.com and got very different
download speeds.

Computer 1, a 2.6 GHz clone with an Intel mobo usually connected to the
router at 48 to 54 mbps, downloaded at 755 kB/sec.

Computer 2, a Dell 2.4 GHz 4600 desktop usually connected to the router
between 24 to 54 mbps, downloaded at 75 kB/sec.

Computer 3, a Dell 3.4 GHz 4700 desktop usually connected to the router
between 18 to 54 mbps, downloaded at 37 kB/sec

While Computer 1 seems to often have a better connection to the router,
would this alone explain the faster download speed? If not, what might I do
to speed up the two Dells?

I would turn off Computer 1 and see if that changes speed result. Also
do all three have same amount of memory?

Was this a valid comparison ?
Was each PC tested while the others were off ?
Where they all in the exact same location while testing ?
Was this all done at the same time of day ?

I redid the test for Computers 1 and 3 which are in the same room. This
time Computer 1 downloaded at a little above 1,000 kB/sec. Computer 3
downloaded at about 39 kB/sec so pretty close to the first test.


I'll redo the test. It's not possible to move all the computers to the same
place but I'll do the download one at a time. I suspect I'll get much the
same answer. After I did the test, I tried it on my Sony laptop running
Vista and I got around 1,000 kB/sec.

Are all three computers connected via wireless connection?

Kinda looks like you're measuring the speed of your unspecified
boradband connection. I can't tell for sure because I don't know if
kB/sec means KBytes or Kbits/sec.

Find a copy of iperf or jperf. (JPerf is easier to use).
Put it your fastest machine, using a *WIRED* ethernet connection to
the WRT54GS. Set it up as a server.

Run the iperf or Jperf client on the other machines and see what
happens to the speed. This way, you're measuring the speed of a
single wireless connection, not the speed through your broadband
connection.

Run the test with various wired and wireless combinations and record
the results. My guess(tm) is that you have widely varying physical
locations for the various machines, resulting in widely varying signal
strengths, which are resulting in widely varying performance. However,
I note that you say "usually connected" between something and
54Mbits/sec. That may be the initial connection speed. However, once
you start moving data, and the system starts seeing errors, the speed
will drop. As soon as you stop, it will climb back up to 54Mbit/sec.
Not all wireless clients do this, but I'm fairly sure that the WUSB54G
does it this way. Just watch the connection speed while it's moving
data, not while it's stopped.
