What happens when they're working separately? Near 50 on each? And what is the configuration now so that we have it one place for looking at the new question?

[jason4656]

what configuration would you like to know?

i obviously dont run the tests at the same time? lol

here is on the vaio


and directly after it on the mac, sat next to each other in same room

btw changing to use the same servers ie bham coventry gives slightly different reading but not enough to make it worth noting

ok, in the settings on the vaio, i have enabled throughput enhancement in the settings, which is within the device manager properties of the wireless card, which seems to have made a big difference, am getting = speeds on them both now, there are alot of settings on the vaio hardware, but I dont know where they are on a mac

OK - as you've got equal speeds on the two PCs we don't need to go into the settings. I think the final piece in the jigsaw is to run simultaneous speed tests to see how it all behaves. If you got downloads going simultaneously, you'd have a definitive outcome IMI.

A speed test preferably using http://www.virginmedia.com/testmyspeed/manual.php.

ok downloading this file

http://gamefiles.virginmedia.com/blu...eandb_demo.exe

both using the same setup firefox latest version and dta set to download on max segments which is how i always use it.

the mac goes straight to 5.4 mb/s and stays there solid

the sony goes to 600kb stays there, slowly creeps up to 3.37mb/s by half way through the 1gb file and thats the best it got

so there is a difference

thanks

For accuracy, let's get the bps and BPS right.

Assuming they were running at the same time:

MAC = 5.4 MB/s
PC = 0.6 MB/s rising to 3.4 MB/s

I take it that the 3.4 MB/s occurred when the Mac had finished its download.

The 5.4 + 0.6 is exactl;y what a fully performing downstream would deliver.

So, do we need to look at the PC and it's wireless settings?

[jason4656]

yes those are correct, i ran them separately of course. I am presuming 50mb is available on 1 pc at a time, not both of course, so I wouldnt try to get simultaneous 50mb connections

The card in the vaio is intel 5100 AGN

There are 13 properties in the hardware settings each with a value

in relation to 802.11n there are

802.11n channel width for band 2.4 / value = auto / choice = 20mhz only or auto
802.11n channel width for band 5.2 / value = auto / choice = 20mhz only or auto
802.11n mode / value = enabled / choice = enabled or disabled

I was trying to get you to run them simultaneously. But you say you ran them separately. Can you confirm what you actually did? Then we'll return to the Vaio question.

[jason4656]

downloaded on mac waited till finished then ran same test on other pc

[Sephiroth]

You've never told us the router you have. (Nonody'd asked!). Now need to know.

I would suggest doing the downloads simultaneously. I think also we've got quite a way to go to bottom this out.

When you've done the downloads with the laptops in the current position, can you swap them round and report. Even if the Vaio speed increases slightly, it'll speak to the effect of the PC that's nearest to the wireless router getting better service (because the signal is slightly stronger).

Then there's the 5100 AGN and its configuration. There's a lot of stuff about on this. Have a look at these two links and compare against your configuration. As we're focusing now on the Vaio, simultaneous tests won't be necessary for the next stages.
