Internet speed getting faster but more dropouts

Recently (with the past 2 months) my internet speeds have been going through the roof. I was at about 6.5 Mbs however now i'm around 11 Mbs however the problem is that we now get a lot more dropouts than before and i don't mean wireless dropouts this is on my ISPs end. I was just hoping if anyone has some information or advice about what to do. before the speed increase the connection was fine.


I'm in the UK and my service provider is currently talktalk (terrible service don't go with them)

 

I assume it's DSL connection. Could you log in to the modem and post DSL statistics like Noise Margin, Line Attenuation and Line Rate?

 

yes here it is hope it will tell you something as i have no idea what it all means besides down rate and uprate

 

Noise margin is very low and line attenuation is very high- that means you're barely connected. If your line is ADSL it's the very limit, if it's ADSL2 it's kind of workable- only ADSL2+ could work with this speed and this line attenuation.

Take a look at this graph- you'll see what I mean.

 

I do have ADSL2+

 

You do, but I'm blind- I somehow got into my head that you have 8mbps connection rather than 13mbps.

So I misinterpreted it a bit- obviously with line attenuation of 36dB you can't hope for a really stable connection at 12-13mbps (see the graph).

Mind you- line attenuation changes with humidity a bit so one day it may work the other day it will disconnect. You may want to make sure that all the cables and connectors are OK, disconnect the phone for testing (older ones sometimes make things worse as they add up to noise).
Most likely none of these will help- in reality you should try to contact your ISP and if they are not willing to modernize your phone line- downgrade your Internet connection- with the very same line attenuation and 8-9mbps connection it would be perfectly stable.

 

I was having many drops on Verizon DSL - ADSL2+ here in the USA with verizon, one thing that really helped was the install of a spliter in the NID and a direct line from there to the router/modem.
They also downgraded my DL speed from 1125 Kbs to 925 Kbs
Then I was able to remove the filters on my 3 phones . I am 2.5 miles from the CO so I realize I will never have a totally stable connection.

@downloads when you say "modernize your phone line" it what I posted above what needs to be done? Thanks, Josea

 

Might have nothing to do with your local-loop speed.

Your ISP could easily have upgraded the pipes into your dsl distro frame chassis or the whole of the ISP.

As for the 'dropouts', that can easily happen on a 'marginal' dsl circuit. A marginal circuit that behaves at lower throughput can start failing at a higher throughput. If your provider has upgraded their backend enabling faster throughput to you, that can cause a higher apparent level of errors and corrections which you see as dropouts.

Without getting an honest report from your provider, there is no way to be sure; it's all speculation.

 

They can measure attenuation and noise levels too so they know that your line is barely operational at this speed. Many things add up to noise levels and that is attenuation apart from the distance from DSLAM.
If ISP feel like it that can modernize/replace some equipment to decrease noise levels and line attenuation- I know my ISP did it for me although I never asked for it.
You can also ask them to manually synchronize your connection at lower speed like 10mbps which should work on a line with 36dB attenuation.

 

Thanks a lot Downloads-
Here are my stats, but no need to respond, maybe someone will see this & get a good laugh (BTW Attenuation numbers rarely change, even with a new line from the pole to the NID).
In the past 2 years techs have been onsite 8 times - guess its time for FIOS
Thanks for the Graph link above
Vendor ID Code 4D54
Line Mode ADSL_2plus
Data Path FAST
Transceiver Information Down Stream Path Up Stream Path
DSL Speed (Kbits/Sec) 925 445
Margin (dB) 6.8 18.6
Line Attenuation (dB) 59.5 39.7
Transmit Power (dBm) 17.8 12.4

 

JOSEA- your data path is set to FAST, you may want to have them change it to INTERLEAVED which increases ping slightly but makes sure that no packets are lost. With attenuation like yours it should be set to INTERLEAVED but that can be changed only by ISP.

 

Great insight Downloads, when I used to get the full promised Download speed 1Mbs ~ 1125 Kbs It was set to interleaved.
I love how the agreement was changed to a range of Download speeds (700 Kbs - 1125) recently. I really apprecite your help.
