Just a thought, wireless entails encryption, wired is a straight through
connection. That takes overhead, and reduces your throughput.

Another thing is that wireless also take additional processing power
from the router. Again slowing the speed.

I had the same thing happen to me on a dlink unit. I switched to a new
unit with a faster processor and my speed went up. It is still slower
than wired, but much better.

i am using a dsl speed report but i can also see what my speed is via
downloads

i had a blekin wireless g adaptor it dosnt even install on windows xp
sp3 but i have removed all the information from that adaptor from my
computer i have also noted when trying to find another adaptor to
replace that one that other people have had problems with other
wireless usb adaptors on windows xp sp3

the router is D-Link DI-624 Air Extreme Plus it has the latest
firmware updated it when i brought it. as for the security i just
used the first one i selected i will try to set up wpa. i know
different security models have different overheads and i know these
overheads do take up some bandwidth. i notice when i disable my
security my down rate it goes up by 100-200 kbps but again it is
still quite low compared to my wired connection. and i do concede
that i will not get all that power on my down rate bout i would at
least like 2/3 the rate so 10000kbps.

as for the hardware revision i will have to check when i get home.

nope using usb 2.0 as stated above my speed increases to ~7000kbps
with no encryption. my asus program show i am getting 48 - 54Mbps
stable. but that dosnt matter as i can be sitting right next to the
router through wireless and it makes no difference.

pity i dont have another computer not anyway to obtain one for this
test.

but woudl that note why my up connection to the wireless is 700kbps
and my down is 400kbps. or is it that there is no encryption on the
up connection only on the down connection.

I have two Belkin F5D7050 54G adapters on WinXP SP3 machines.
There have been no problems with drivers. One was installed on the PC
before SP3 came out, the other was installed this week, with SP3 already in
place.

As another poster mentioned, the cable that was supplied with the first
Belkin was thin, and I had problems with lockups that went away when I
substituted a commodity USB cable.

Belkin no longer supplies the little stand and wimpy cable. The
new adapter is plugged directly into a port on the back of the PC.

I installed the Belkin package, but elected to use Wireless Zero Config.
f5d7050v3_ww_03.00.07_w2.exe was downloaded from the Belkin site.
<http://en-us-support.belkin.com/app/product/list/q/network-adapters>

OS Name Microsoft Windows XP Home Edition
Version 5.1.2600 Service Pack 3 Build 2600
Product Type Belkin 54g Wireless USB Network Adapter

There are several variants of the same named adapter, with different
downloads for each. They might be completely different chipsets, requiring
different drivers, but that wouldn't be specific to SP3.

Decent wireless USB adapters work fine on Windows XP, Blekin (pun
intended) notwithstanding.

A common problem is buying on price alone: fast, cheap, good --
pick (at most) two.
