Hi all,
I have Asus laptop with Intel Pro/Wireless card 3945ABG network card running the latest drivers and I am connecto to a Netgear router.
My problem is that I have a 20MB internet connection and when I run a speed test (www.speedtest.net) I get very odd results.
If i am wired directly to Modem - 19800MB
IF I am wired to the router - 15500MB
If my I use my wireless connection - 5400MB very very little.

I did the same test with a Dell Inspiron 6400 and I got same results but on the wireless test I got 15000MB. So something is wrong with my wireless connection but i dont know what. I unistalled the wireless card and drivers and Intel applications. reboot computer and it auto detect new hardware and installed using windows XP tool and still i get the same results. I have bring my router to factory defaults if case problem was with any IP routing but still I have no results. I tried with antivirus and firewall off anf the results are the same.

What can this be? Will I have to format my OS?

Any comments are appreciated.
Thanks alot.
Larbac

You are misunderstanding the capabilities of wireless connections.

Any wireless connection is only as fast as the prevailing environment around it will allow.

Also the rating of 54Mbps is what the MAXIMUM capability is, not what it will usually perform at.

For a start, you have to heed the difference between Megabytes and Kilobits - each of your quoted speeds should be Kb, not MB. You have posted with speeds that are instantly 10x^3x8 above reality. ;)

Personally, I am sitting in the Scottish Highlands on a supposed 8MB connection, and my Speedtest.net result has just come back as: [b]6,197Kbps download / 304Kbps upload[/b] - I am content with that, given the local time and my geographical location. If I were located in Glasgow or London I might complain with this speed result, [i]then again I'd probably not [b]unless it really mattered.[/i][/b]

My Speedtest.net score of 6,197 is for Kbps, so to figure out my MBps score I divide it by 800, which comes out at [b]7.74MBps[/b]

Your score of 19,800Kbps comes out at [b]24.75MBps![/b]

[b]THAT is why I don't believe your figures - you are getting 25% MORE speed than you are quoting you SHOULD be getting - and you're still complaining! [/b] :^0

Your Speedtest results should be checked again.

[u]You have effectively just shot yourself in the foot![/u] ;)

What are you using your system for?
Why are you SO concerned about the figures coming back from Speedtest.net?
Were you concerned BEFORE you knew the figures? ;)

Remember - a little knowledge is a very dangerous thing. ;)

And never forget that there are EIGHT bits in a byte, a thousand bytes in a kilobyte, a thousand kilobytes in a megabyte.

Some educational links for you:

You would do well to learn the subject of wireless and transmission speeds in general, before you go off at a tangent again.

Thanks alot for your answer. You are right I made mistake when I posted 19800MB while should be read Kbps. Anyway I have two laptops one sitting beside the other and using the same websites I get very diferent results.We are talking about when im wireless not wired.
Anyway i am on a suppose 20MB connection. And better then words here are some images.
Here is my speedtest result while WIRELESS

Here is my speedtest results while WIRED

On my other Dell PC i have more constant test where wireless i get 14000kb/s

All this makes me to believe is something with my laptop no?

I've just tested again at Speedtest.net and this time my result is [b]6,910Kbps / 366Kbps[/b]

This time it comes out at [b]8.63MB[/b]

Just shows - you can't complain about one set of results. But it does help if you know how to interpret them. ;)

i totally understand but my results have a trend and i have been testing it evryday since past week and more and less the results are the same... Still huge diference between my Laptop and the Dell one.

With the g Standards in WiFi Networking it's top speed is 54 MEG per second which is what it is showing you have.

Wireless networking is always considerably slower than a Wired Connection. There is an old saying here that goes along the lines of [b]You can't have your Cake & eat it too.[/b] So if you want the flexibility of Wireless you have to expect slower Networking Speeds.

Of course the speeds that you are seeing are at best Projected speeds not the actual Real Speeds that will be realized. WiFi will be slower as there is Security to be included in all Network Traffic that isn't necessary in Wired Connections as well so WiFi will remain considerably slower connections.

Thanks for your reply and I do understand what you say. But my surprise is why such diference betwwen both wireless laptop test.
Is it someting I could configure in one of the laptop to achive same results as the other?

The slower one just isn't a G Type Adapter it's an earlier type one that will not reach the 54 MBS Speeds that are currently the Stated Goal of the G Series Adapters.

If you have a 802.11 b WiFi card it's slower than a 802.11 g Card and so on with the current [b]G[/b] being the fastest possible. Then even if it was a G Standard Adapter there is no saying that the Interface tot he NB's M'Board is as fast as it needs to be to support the G Standard. Some NB Makers just don't correctly setup the hardware that they supply and may include the faster WiFi Card to sell product but not provide a way for it to reach it's full Potential. Just the same as supplying a Dual Chanel RAM M'Board with 1 Stick of RAM will never reach 100% of the capability of the Hardware but it's cheaper than selling the correct hardware to do the job. :D

And people thought that MS protocols were "chatty". Take another 25% off the top?
