Connection speed slowed down massively

Greetings everyone,

 

Whats going on here?

 

I've recently noticed the internet connection at my grandma's house has slowed down for no obvious reason.

The connection used to be at least 6Mbps down but now it's almost useless.

In addition, the connection seems unstable and drops far too often. The noise ratio seems high so maybe the line is faulty.

 

 

The Hub is turned off most of the time but the connection was fine before regardless. The master socket is up-to-date.

 

ADSL2+ should get at least 10Mpbs in this area. I can get 16Mpbs on a line not too far away. Personally I think BT are pretty rubbish.

 

 

BT hub stats:

 

Line state:Connected
Connection time:0 days, 00:34:06
Downstream:286.3 Kbps
Upstream:446.7 Kbps
 
ADSL Settings
VPI/VCI:0/38

Modulation:G.992.5 Annex A
Latency type:Interleaved
Noise margin (Down/Up):27.7 dB / 29.1 dB
Line attenuation (Down/Up):37.2 dB / 22.2 dB
Output power (Down/Up):17.6 dBm / 12.5 dBm
FEC Events (Down/Up):0 / 355
CRC Events (Down/Up):1 / 1781
Loss of Framing (Local/Remote):0 / 0
Loss of Signal (Local/Remote):0 / 0
Loss of Power (Local/Remote):0 / 0

Re: Connection speed slowed down massively

Leaving it turned off means that the exchange thinks its a fault, and put the line in a low banded profile.

 

You must leave your home hub turned on and connected to your phone line for at least five days.

 

During that time, do not reset or disconnect it.

 

Your speed with then increase.

 

Its best to leave it on all of the time.

Re: Connection speed slowed down massively

Hi Welcome to the forums

Here are some help pages done by CL Keith http://forumhelp.dyndns.org/speed/Speed.html

it is reccomended that a hub should be powered up 24/7 to provide the most stable connection 



Can you also post the full results from BT Speedtest speedtester.bt.com  Test Socket.jpg

Have you tried connecting to the test socket at the rear of the master socket

Have you tried the quiet line test? - dial 17070 option 2 - should hear nothing - best done with a corded phone. if cordless phone you may hear a 'dull hum' which is normal


This is a customer to customer self help forum the only BT presence here are the forum moderators

The quiet line test was inconclusive. There was some crackling but it disappeared after removing the filter and then plugging back in again.

ok the line noise will not have helped hope fully you have cured that moving the filter however it is very important to have the hub switched on all the time

It's been a while.

 

I've been made aware keeping the Home Hub turned on is not an option. Appliances are turned off here when not in use.

 

There have been some random disconnections which suggests a fault. It used to run at full speed and the hub has never been turned on constantly since BT ADSL was enabled.

 

I think BT are rubbish BTW.

Re: Connection speed slowed down massively

Unless you leave the hub on 24/7 you connection will keep doing this adsl2+ is very sensitive to noise and turning the hub on and off is seen  as disconnections and noise there fore you connection will suffer this will apply to any ISP NOT JUST BT

 

As  parallel  would you turn your freezer off every night the answer is no as you would lose what is in it the same applies to the hub turn it on and off then your broadband will suffer  

1 never improve 

2 you will constantly have speed and line stability problems

Hi Panmaster,

 

With the old fixed broadband you could do whatever you want to it (ie turn it off at nights/ when not in use) and it will stay the same.

 

However these days the hardware in the exchanged requires a 24/7 connection with the hub to maintain speed otherwise if it's turned off the exchange can't tell the difference between off and fault so it will increase the noise margin and decrease the speed to prevent errors building up on the line.

With the new ADSL2+ service it is more aggressive to any noise on the line, and with it being turned off the noise levels increase causing the line to become unstable. 

 

This will happen with any ISP you use. 

 

cheers,

James
