BB speed dropped after changing provider


[link to this post]
 
Hi there.
1st time on here so apologies if this has already been covered (as I am sure it has somewhere)
I have just changed from Sky to Utility Warehouse(UW) who use Talk Talk and the speed of my broadband download has dropped from around 19M to 12M. As it is the same wires and everything how is this so. UW provided my with a new router and I have done the test both wireless and with a direct cable and the results only improve by 1M. Can someone explain how this happens as I was told it would be a like for like service? Thankyou in advance.

We presume this is an ADSL2+ based service.

The default for TalkTalk LLU can be to run things at a more stable but slower speed using a higher downstream target noise margin.

So technically a like for like service but erring on the stability side perhaps costing you some sync. The before and after router statistics, connection speed, attenuation and noise margins will reveal if this is the case.

Thanks for that. Would that explain that although the stats say it is slower we have noticed that it doesn't drop out like it used to with Sky (touch wood).

They will change the config so that you get more speed for you money, but you have to ask, if you where seeing disconnects then this could be a line fault, and should be reported to them, so they can get an engineer out to find & fix it,
But to go from 19mbps to 12mbps is taking the wee wee imo

Yes. Setting the target noise margin higher has two effects. It causes a lower connection speed, which reduces the error rate, and it makes disconnections due to electromagnetic noise somewhere less likely.

The indispensable man or woman passes from the scene, and what happens next is more or less the same thing as was happening before.

And where interleave is applied plenty of LAG not ideal for gaming

Depends on the level of interleave and if interleave means less errors while the latency may be higher, it can make things consistent which is actually better to play with than latency that is all over the place.

It would be helpfull for all to see the full router line stats as previously mentioned smile

Have a look here then copy and paste them.

Hi all. I think these are the line stats that were requested. Not really sure what I am looking at so hope this is correct. After speaking to UW yesterday something did happen overnight as the speed has increased to 13.5M.
Have a look and see what you think:

Uptime: 0 days, 5:18:08

DSL Type: ITU-T G.992.5

Bandwidth (Up/Down) [kbps/kbps]: 1,020 / 15,767

Data Transferred (Sent/Received) [MB/MB]: 21.74 / 422.59

Output Power (Up/Down) [dBm]: 12.8 / 0.0

Line Attenuation (Up/Down) [dB]: 6.2 / 14.0

SN Margin (Up/Down) [dB]: 12.9 / 9.1

System Vendor ID (Local/Remote): TMMB / ----

Chipset Vendor ID (Local/Remote): BDCM / IFTN

Loss of Framing (Local/Remote): 26 / 0

Loss of Signal (Local/Remote): 3 / 0

Loss of Power (Local/Remote): 0 / 0

Loss of Link (Remote): -

Error Seconds (Local/Remote): 37 / 0

FEC Errors (Up/Down): 0 / 145

CRC Errors (Up/Down): 0 / 5

HEC Errors (Up/Down): 0 / 84


Thanking you all for your time here. Its really helpful.

Cheers

Connor

ps. I just got this report aswell several minutes later. looks like it gives more details.

Hi there, you should really go back into your last post on here, use the 'edit' button and remove your IP address and your telephone number 9at the start of your username) from the post.

As for the stats, you are still set to 'comfortable' mode by your CP ..

SN Margin (Up/Down) [dB]: 12.9 / 9.1

Reduction of the the downstream target SNR from 9 to 6db will produce more sync speed. This can be done via request to your CP.
