Wireless Seems Slow !

New Belkin 54g PCMCIA Card & 54g Access Point.

transfering 2.5GB File from pc to laptop took 18Mins.

Throughput is measured @ 20MB is that right ?

I thought with 54g I should get faster !!

Thanks

802.11g is 54 Mbits per second - bits not bytes.

So divide by 8 (although it is more like 9 or 10 counting admin
overhead) and you should be getting 6 MB/s at best.

I make it that you are getting just over 2 MB/s (2500 MB /18/60) so
maybe you are not connecting at full speed. That is entirely possible
unless the two systems/access point are next to each other.

did you download the latest drivers from belkin? I just bought a 54 Mb
pcmcia card myself and the driver on cd is not capable of connecting to my g
standard access point. I downloaded the latest software and then and only
then did the card establish a 54 Mb connection

Main thing I have noticed so far with my WiFi (Netgear 802.11g) is
that it does ** not ** do what it says on the tin.

I think the 54mbps is very optimistic.

I've had my AP and two adapter cards all within feet of each other and
got nowhere near 54mbps.

Belkin 54g Access Point is on the table next to the laptop !! Less than 3
foot apart

According to the Belkin software, the connection is @ 54MB and is
Excellent..

The access point is set @
54G-ONLY
Turbo Mode ON
Protected Mode OFF

The Belkin PCMCIA 54g Card is set @
54g-Performance
Protected Modem AUTO

I have 128-Bit WEP Enabled..

Is this correct, how do I get the best out of them..

Many Thanks

Tom

you aint kidding...

I have USR 22mbps kit and get nowhere near that rate, more like 8mbps
even at close range (1m).
a 644mb file took just over 10minutes to transfer

I think you probably have the best you'll get.

I have an 802.11b setup (does "a" as well but I haven't tested that for
speed) which reports a 22 Mbps connection turbo mode). It took 33
seconds to transfer 20 MB. Unless my math is mixed up that's 0.6 MB per
second which is a quarter of what you were getting. That's regardless
of range (2 feet or 20 feet and two concrete walls) or signal strength
(from very good to very low as XP so helpfully reports).

As some else pointed out, G is 54Mbps (Megabits/sec). My calculator says:

2.5GB * 8 = 20Gb = 20*10^9 bits
18min * 60 = 1080 seconds

20*10^9/1080 = .0185*10^9 = 18.5*10^6 = 18.5Mpbs

Many studies have been done on real-world B and G networks, and the numbers
I have seen (you can find them for yourself by doing a net search) are in
the range of 18 - 22 Mbps for G, and for B (which is nominally 11Mpbs) 4 - 6
Mpbs.

I think your performance is well within ordinary bounds.

802.11b - max 550 kilobytes peer second
802.11g - max 2 megabytes peer second

tested with Windows Commander

I've just tried copying the same 2.5G file from my PC to my server, using
CAT5 not wireless.

That's averaging 24 / 25 Mbits

Not much difference between that and the wireless. The wireless was about
20Mbits

I'm using an ADSL Router with built in 4 port 10/100 switch to connect 3
PC's via CAT5 and have the belkin access point connected to this also.

Thanks for all the help and advice !
