Quick query about ADSL speed

A full 24,574 kbps sync on ADSL2+ would translate into something closer to 2.61 MB/s (2.55 MB/s in Windows as the file manager misuses SI notation), non?

/pedant

Not with overheads and ISP side throttling its unlikely he will hit the maximum, even on my BE connection im syncing at just over 18mbps and on newsgroups I can only get around 1.65MB/s
 
Running speed tests connects me at about 19mb, this is on wired, switching to wireless sees the speed drop to about 11mb. I literally have the laptop about 1ft away from the router when running the wireless speed test so I am pretty sure the wireless cannot be getting a load of interference which would cause it to drop 8mb.

I rang up Sky, not expecting much, they advised me that wireless is never as fast as wired and it is usual to drop so much speed. I pointed out my last network was had a Cable 20mb connection and I would receive 20mb over the wireless. Sky 'tech guy' suggested changing the chanel, I have tried 4 or 5 different channels, all yield the same results.

It is a Sky Router that only supports G mode but even that should be plenty for a 20mb connection, is it a case of the router being seriously rubbish or is there some massive interference? The wireless signal is full bars aka Excellent.

Any help would be appreciated!
 
I'm on Sky BB and get the full on 20 meg connection. The fastest i've ever had a download was about 1.9MB a second so I doubt you'll hit 2MB. my line can apparently support 23.5 Meg but Sky tops that at 20Meg. And that's wireless.

If G wireless supports up to 54meg and your BB is running at 20meg, which is faster? Sure you add on a few overheads on wireless but I've run two consecutive line tests, one wired, one wireless and there was little to no real difference. I'm not in my test socket but only have a single socket and my exchange is over 700m away according to Sky. The fastest I've ever got from speedtest.net was around 17meg but Sky won't take that as any indication of the speed you're getting and will always go by the Router sync speed.

My stats right this second are:

ADSL Link Downstream Upstream
Connection Speed 19953 kbps 1157 kbps
Line Attenuation 15.5 db 10.2 db
Noise Margin 7.1 db 9.0 db

Directly from the Router.
