My connection stats

[ShadeX]

ADSL Link Downstream Upstream
Connection Speed 6016 kbps 768 kbps
Line Attenuation 35.0 db 19.5 db
Noise Margin 11.1 db 13.0 db

I phoned sky letting them know that im on the max package. They did a few checks on there system. They then told me that my line can only handle 256kbps. So are my router stats above wrong or has sky got something wrong. I told the sky engineer on the phone that my router is showing these stats he told me thats a bit wierd and theres nothing he can do to increase my speed.
So basically im a bit confused on how fast my internet speed is. I ve tried a few internet speed websites the test results were around 2.5mbps - 3.2mbps.

Jinx! We have the same attenuation!

ADSL Link Downstream Upstream
Connection Speed 12793 kbps 950 kbps
Line Attenuation 35.0 db 19.5 db
Noise Margin 7.1 db 8.0 db

So based on attenuation, It shows you could be able to go faster? So, You could try testing with your mastersockets test socket?

@Shadex Your Noise margin seems rather high, perhaps reducing that with the utility available via this forum may help your speeds. Set it to around 7db.

It may be that Sky have capped you?

@FibreOptic ive pluged it in the master test socket and there was no change in the connection speed, the line Line Attenuation stayed the same, the noise margin had increased a bit.

@ Disillusioned my noise margin has recently gone down to about 7.5db for some reason.


The only thing i still do not understand is that sky told me that my line can only handle 256kbps but my router shows that im getting a consistent 6meg connection

The fact that your connection speed stayed the same and your noise margin increased strongly suggests that your connection has been capped by Sky for some reason.

To get an understanding of the relationship between attenuation, speed and noise see here.

If you are getting significantly slower download speeds than your router connection speed then it could be your TCP/IP settings need adjustment. See here.

I'm afraid your experience has shown that sometimes you get pure nonsense from Sky - cynically you'd almost think they make things up for a joke. Your line can clearly handle more than 256kbps as can 99.9% of lines that are ADSL capable. In fact, providing you do a little work to improve your line noise, with your attenuation 14000kbps could be achievable.

Read through the links I've suggested, make any changes you see fit to improve your connection then get back to Sky and ask them what's going on and that you want your connection uncapped.

My noise margin is at 7db doesnt that mean i have a low noise margin so therefore my connection speed would be faster or have i got this noise margin all wrong?

[Saturday]

No 7db is not a low noise margin. The Sky router, in most circumstances will always negotiate the highest possible speed at a noise margin of 6.9db. So the vast majority of people will find their noise margin to be ~7db whenever they reboot or power up their router.

You do however need to ensure that your noise margin doesn't drop too much lower than this though.

As I suggested before, read this for more info.

My noise margin seems to be improving

6016 kbps 768 kbps
Line Attenuation 35.0 db 19.5 db
Noise Margin 12.4 db 14.0 db

I phoned sky to tell them to take the cap of my broadband. They said i have to give it a few weeks as ive only had sky bb for about 5days.

It would be really helpful if you'd read the link given (2 times now) then you might understand why noise margin changes.
