Net has been capped to 148k for 2 weeks and counting....

I have had no issues this year with broadband, a stable 2Mbit with few to no disconnections, until recently.

 

A few weeks ago, BT finally upgraded the local exchange to 21CN after originally setting the official date to 31/03/10.

 

I received an email early on the morning of said upgrade date to say that it had been done and the usual, allow 7 days for it to settle.

 

Ever since, I have either been off the net or on the net with 120k approx.

 

I cannot stream videos, play online games, the only thing I can do right now is browse forums and check mail.

 

Here are the current router stats:

your exchange may have been upgraded but you have not.  your modulation is 992.1 which is adslmax.

 

you have a 2mb connection and with an attenuation of 61 live quite a way from the exchange.  can you run btspeedtester and post the results

The throughput of Best Efforts (BE) classes achieved during the test is - 9.76:16.84:73.4 (SBE:NBE:PBE)
These figures represent the ratio while sententiously passing Sub BE, Normal BE and Priority BE marked traffic.

The results of this test will vary depending on the way your ISP has decided to use these traffic classes.

Browse up time is short is that because you have switched off a lot ? it should be left on line 24 7 to let your profile settle

 

Have you tried a quite line test
dial 17070 option 2 and listen - should hear nothing
best done with old type analogue phone digital will do but may have slight hiss
do not use home hub phone

 

as noise on the line can cause the low profile

Re: Net has been capped to 148k for 2 weeks and counting....

Thank you for you're help with this, how does one go about changing the modulation type please? As samknows has the exchange upgraded with 21CN back in March of this year which still leaves me puzzled as to why I received an email from BT telling me I was upgraded over 2 weeks ago.

 

And from my modulation type I am still on ADSLMAX.

 

Thank you.

Re: Net has been capped to 148k for 2 weeks and counting....

with an attenuation of 61 an upgrade to 21CN would probably make no difference to you and may, because 21CN is more aggressive with noise problems, result in more problems than you have at present  you can check here to see what I mean  http://www.kitz.co.uk/adsl/max_speed_calc.php

Only BT can do that

You may have to sign for a new 12 month contract

 

and go here and enter your line attenuation from stats to see what you could expect  http://www.kitz.co.uk/adsl/max_speed_calc.php

 

 

you will see nothing to gain due to 4.4K line length which is probably why you have not been upgraded
