Speed getting slower

Hi there,

I've always been with BT and we used to always have over 3mb but then speed started to drop and we ended up with 2mb.

So, I ended up replacing my BT home hub 2.0 with a billion bipac 7300 and then got my profile reset and after the 24/h settling progress leaving the router on I've ended up with a speed of 6.50mb/DL & 0.90/Upload.

But, now after about 2weeks it's starting to drop slowly in speed and upload. :(

So, I'm just wondering if they is any thing else I can do to get it to stay at 6MB or any way to get it faster?

Here is some images to help.

Thanks

Your downstream snr margin is quite low and maybe slightly unstable. If the connection drops it may be reporting as a failed connection and dropping your connection speed to raise the snr and gain some stability.

Not sure about other ISP but mine sets snr at 7db.

You should be syncing at full 8meg, do you have your ring wire removed?

Not sure why you think that a line with a downstream attenuation of 51.5db could sync at full 8 mbit. Lines that sync at full 8mbit on ADSL will generally be less than 30db on Attenuation and those that get full 20mbit on ADSL2+ will be less than 20db.

According to the Kitz Max Speed estimator you should be kicking around 4.6-4.7mbit with both ADSL and ADSL2+.

There are a few ways to improve attenuation:-

1) Improve your wiring. (I saw a 3 db improvement over 15m of flat telephone extension wiring)
2) Site your modem right next to the master socket.
3) Move closer to the exchange.
 
Thanks guys.

Well a far as I know if it ain't over 6.0DP then it's good.

Ye, I'll never get 8mb I'm 1.61km from the exchange that's in a straight line.

Well I've already fitted new faceplates, and not sure about how to do the wiring in the socket.

The router is already next to it and is connected to the master socket.

Cant move closer the the exchange.

EDIT: I did go onto http://192.168.1.254/snr.cgi and set it to 200 after the router being on for about 2days.

Not sure if 200 was good number to enter or not though.

Thanks.

TBH a 7.2 sync on a 51.5dB attenuation line is fantastic, frankly I'm amazed you got that high. I'm struggling along with a 2.5Mb sync / 2Mb BT profile on a 50dB line (noisy electronics and crappy wiring so can't get my SNR under 10, but even with decent internal wiring I don't think i'd get much more than 4Mb)

Thanks, well on BT site the estimated speed for my line is 3.5max so getting way more.

Here are the value things
200 = +6dB
150 = +3dB
100 = +0dB
50 = -3dB
25 = -4.5db
1 = -5.5dB

I got told if I set it below 200 I'll get a faster seed, but when I did it would not connect, so had to put back too 200.

Have you tried any of this Zarf

(1) Replace faceplates (if not buy I-plate)
(2) If you have long line then have look at router that is made for long one like mine
(3) Remove bell wire
(4) Get profile reset then leave router connected for 48h

Yes, done them all. Problem is that the internal phone cable from where it enters the house to the master socket travels quite a long way through the walls, and seems to follow the same path as some power cable. I've monitored my SNR margin and get fairly frequent dips that would drop my line if the margin wasn't so high.
I'd like to move the master socket close to where the telephone cable enters the house, but it's all classed as part of BT's network so I can't tamper with it myself and would have to pay hundreds to get an engineer to move it.

Zarf,.... time to be a man !!!!,... I was in the same position.. I cut the wire and fitted a new BT mastersocket where it entered the house. (there are only 2 wires).

If anyone asked me , "the Master socket has always been there ":eek:

Just do it. I some how don't think when a engineer comes out will know it's not in original place. Just make sure you cover up where it used to be.

I just look at it this way 'It's in my house so it's mine to do what I like with it' :p

EDIT:
I've just done by SNR to 150 that works out at 3dB

New statues:
DSP Firmware Version A2pB025f.d22k
DMT Status No Defect
Operational Mode ADSL2
Upstream 1036
Downstream 5290
SNR Margin(Upstream) 5.9
SNR Margin(Downstream) 10.0
Line Attenuation(Upstream) 27.0
Line Attenuation(Downstream) 48.5

Why as it made it worse? /:
