Speeds not what they used to be

I have had sky LLU for as long as i can remember, the day it first became available in my area. I originally got 16Mbps and was very stable, then for some reason it dropped to 12Mbps then recently i noticed it had dropped to 4Mbps, so i eamiled them and complained that it wasn't right i believed it should have been higher, they then decided to put it back up to 10Mbps. My questions are :

1) for my line stats is this right ?
2) I believe the exchange is congested, is this possibly why my speed are so slow?

Port Status TxPkts RxPkts Collisions Tx B/s Rx B/s Up Time
WAN PPPoA 7392 7647 0 0 0 0:20:43
LAN 21606 21949 0 0 1375 0:51:03
WLAN 10890 6552 0 1504 137 0:50:36
ADSL Link Downstream Upstream
Connection Speed 10236 kbps 605 kbps
Line Attenuation 32.5 db 17.7 db
Noise Margin 6.0 db 16.9 d

Could be congestion but equaly could just be a higher take up of Broadband on your cabinet. More users equals more noise equals lower speeds.

Your line is capable of 13/14 Megs, unfortunately your noise margin is on the limit. This indicates a noisy line and because you have problems when it rains, it's likely you have a line fault. You may need an Openreach engineer to fix your line.

Do you have a noisy phone?

Is your sky box filtered?

Try the router in the test socket behind the master to see if that improves your stats.

We don't have a phone plugged in, but on the few occasions i might, the line is very noisy, whistling hissing noises. Our SKY boxes aren't connected to any landlines. The only socket i use is the master socket, which has my modem line connected to it.

You really need to try the test socket to ensure you get phone noise to avoid any possibility of being charged. But you should report the noisy phone and get it fixed. This should fix your broadband.

Back into mis information mode are we?

If Sky were remotely able to get you from 4 Meg to 10 Meg then the suggestion is that it is there line capping that is the issue and not actual line performance per se.

The clue is the way the upstream is being held so far back. The speed caps from Sky along with the power back off keep the noise margins down, so it can look to be a poor line.

Congestion on the backhaul should not affect the line connection speed, and crosstalk should NOT affect ADSL to anywhere near this extent, also you cannot remotely reset crosstalk, so the 'decided to put it back up' really does highlight that Sky are limiting your speed.

I don't think this is correct. The noise margin is too low.

Sky is known to back off the power when it caps a line speed, and generally noise would not result in the upstream being so low and leave lots of spare margin.

Power back off makes the SNR look low for the attenuation and sync speed.

The OP has said he has audible noise on the line and problems when it rains. Sounds more like a line fault than a Sky fault tbh.

Are you in denialnm mode. More users equals more noise. Simple basic fact or are you impling a line and cable bumndle generate zero noise.?

For Postcode BN27 2BE

Your exchange is ADSL enabled, and our initial check on your postcode indicates that your line should be able to have an ADSL broadband service that provides a fixed line speed up to 2Mbps.

Our check also indicates that your line currently supports an estimated ADSL Max broadband line speed of 7.5Mbps; typically the line speed would range between 6.5Mbps and 8Mbps.

Our check also indicates that your line currently supports an estimated ADSL2+ broadband line speed of 17Mbps; typically the line speed would range between 10Mbps and 19.5Mbps.

it's the last paragraph that i find important, i emailed sky to say i had a fault with my home telephone line, not sure if they've fixed it or not, but yesterday it wasn't saying typical 17Mbps. Does this possibly mean they may have fixed my line, i'll add todays stats see if anyone will be able to tell or not :

Connection Speed 10238 kbps 605 kbps
Line Attenuation 32.5 db 17.7 db
Noise Margin 8.2 db 16.0 db

What does your Sky control panel say about your speeds?

Look in My Sky > My Broadband > Conection Details

Your Sky Broadband & Speed Estimate

You have Sky Broadband Unlimited.

When you purchased Sky Broadband, we estimated that the maximum download speed for your line was 2.0Mbps - 12.2Mbps.

The actual Access Line Speed could be lower than this estimated speed range. If the speed is significantly lower please contact us.


Your Connection Details

We constantly monitor your line to make sure it has been set to support the fastest speed possible whilst maintaining a stable connection.

Line connection testing completed on 04/10/2012, resulting in the following settings:

Download speed setting
Your connection has been set to a download speed of up to 4.1Mbps .

Upload speed setting
Your connection has been set to an upload speed of up to 0.5Mbps .

That is what it says, which to me seems one doesn't know what the other is doing

I recieved this email today, basically treating me like a idiot, i have told sky now, i will no longer pay my bill, till this is sorted. I even told them to take me to court, i will print every post from here and sky help forum, showing this isn't a isolated issue with just me alone ! My line is no longer in training, so he is talk baloney, straight off the bat !



Dear ****************



Customer Account Number: ****************

I am sorry to hear that your experiencing slow speed issue.

I have checked your account and see that the line optimisation is in progress as the line is unstable due to which the Optimisation is in progress. However, I have made the necessary change on your Broadband speed.

The current down load speed is 10.2Mbps as the line can support only upto 12Mbps. Hence, I have configured the speed to the maximum your line supports.

Please check the speed at which your broadband box is connecting to the internet, follow the outlined steps:

Open a new browser window
Type 192.168.0.1 into the address bar
The username is admin
The password is sky
Under the sub heading Modem you will see your downstream connection speed.
This speed is an indication of what your line is actually capable of on your current package.

I hope this information has helped with your enquiry. If you require any further assistance, you can respond to my email.

Kind regards

Harish R

The joys of a DLM system that works around setting a speed cap, rather than a target noise margin I am afraid

Is your phone line still noisy?

I am the first to complain when things are not working well, I woke up this morning to check my email and noticed my line seemed quicker, i checked my stats and it now says :

ADSL Link Downstream Upstream
Connection Speed 11445 kbps 945 kbps
Line Attenuation 32.5 db 17.8 db
Noise Margin 9.3 db 12.5 db

I guess it just goes to show, i was being capped, I think this all changed when i went on the official sky forum, told them I am notg paying another penny, take me to court, I'll print off every complaint of slow speed i can find to take to court. I got a PM on the official forum asking me for my details, I guess moaning positively sometimes helps

I got an email telling me they're going to sort it out, so until i hear different i guess, my line is still noisy

That's what is causing your problems.

Has it stopped raining?

It certainly has LOL also just got another email of sky and now have these speeds :

Connection Speed 12147 kbps 767 kbps
Line Attenuation 32.5 db 18.0 db
Noise Margin 7.8 db 16.7 db

So i guess what everyone has said here, I was purposely being capped, and they have arranged for my phone line to be fixed within the 72 hours
