Speed STILL Dropping After BT Visit!

[DoctorGore]

So if anyone would like the background to this thread, here's the thread I made to try to find the cause of the problem with my connection speeds;
http://www.skyuser.co.uk/forum/sky-b...d-problem.html
Thanks to everyone who helped btw. I thought we had it sorted, but my luck lasted a mere few days.

After BTs visit we were getting a solid 1604 down, which translated to about 1.3MB. Nothing spectacular, but it was a whole new world compared to the 128kbps I was getting beforehand. I've bin doing daily checks to see if our connection changes, and it has. Yesterday it dropped to around 1400kbps, and today it's dropped to 1347kbps. Here are my current stats;

System Up Time: 145:59:52
Port Status TxPkts RxPkts Collisions Tx B/s Rx B/s Up Time

ADSL Link Downstream Upstream
Connection Speed 1347 kbps 413 kbps
Line Attenuation 69 db 44 db
Noise Margin 9 db 13 db

The download attenuation has only increased by one, would that be why it's dropped? We haven't changed anything in our setup since the BT visit. We have a new wireless laptop, but that was used for the first time today. I know this may seem too small for some people to consider a problem, but with a connection like mine, every kb counts haha. Also, I've noticed that my connection starts to fall off over a few days, so this seems to be doing the same.

Please help!

Your sync hasn't dropped in 90+ hours. Reboot the router and you'll likely see it at 1.6mbps.

Here are the results after your suggestion;

Note that all the second Speedtest.net results were done after only one reboot. I also noticed that even though I eventually got 1.6MB (which is the highest I've ever seen on my live) that the down speed on the stats stayed at the same (1587kbps). After I wrote that last sentence, I took another test. I'm getting 1.3MB again. Was there just a glitch in the amount of overhead or something?

I am getting a bit fed up saying this, speedtest.net is not consistent. The fact that you got a higher download speed than your sync speed proves this. It is just not possible, so ignore it. The tester on this site will give more consistent and truer results.

Did you ask them to try your line on G.DMT? If so did they just fob you off and say it would not matter?

[DoctorGore]

Ah right ok.

I'm on the phone to them atm, just got put through to the higher level of customer service. I asked the woman if she could try my line on G.DMT but she didn't really get what I was saying, hence why I'm waiting to talk to the higher level. I'll update the thread after I'm done.

Well the woman I was speaking to originally picked up the phone and told me she got the people to try my line to G.DMT. I asked if it was possible to increase my upload aswell,.she told me they tried increasing 'everything'.

Here's my stats after the line switch;

System Up Time: 22:24:57

Noise Margin 7 db 14 db

The download speed is the highest I've seen on my line, dunno what it'll translate into actual speeds though, about 1.5MB I'm guessing? But the upload has stayed the same. I noticed my down noise margin is at a consistent 7db now, that's good for Sky right? Actually, there doesn't seem to be any fluctuation in anything now, before there'd be maybe a 1db fluctuation in my noise margin or attenuation. Does this mean my line is more stable on G.DMT?

Connection just randomly dropped to 256kbps...

Maybe my line is less stable on G.DMT? I mentioned that the noise margin wasn't changing any more in my last post, but that was just for the first few hours. It started fluctuating between from 7db, then down to 5db at some points.

Anyone know what I should do? My line started slowing on both ADSL2+ and G.DMT...

[DoctorGore]

I decided to leave the router on to see if the speeds change, here's my stats now;

System Up Time: 40:31:05

ADSL Link Downstream Upstream

Noise Margin 7 db 14 db

It's back up to around 1.7MB, just a few kbps less than it was before. I'll update if things start changing again.

[Isitme]

It looks like your line is suffering from a lot of noise at night. Reboot and see what you get. I think the fact that your line got its best speed with the default noise margin shows that G.DMT is probably the best setting, but the line is just not good enough and like many, suffers from excessive night time noise.

[DoctorGore]

Damn. I just found out about the difference in kilobytes and kilobits, so my maximum transfer rate or whatever, is 212kb. But even then, when I download something the rate varies wildly. Is there any way I can max out the speed at all times?

[DoctorGore]

So the weather has bin bad today which normally effects the 'net, and today it dropped to around 444kbps. So first, I rebooted the router. It had been on about 60 hours. It stayed at the same speed (~444kbps) then sunk to zero, now it's at the highest I've seen it yet;

System Up Time: 00:07:01

ADSL Link Downstream Upstream
Connection Speed 1824 kbps 416 kbps

Noise Margin 7 db 14 db

Is it faster because they're trying to make up for the interruption the weather is causing?

Oh, and would DLM help now? Since my line appears to be more stable on G.DMT?
