My broadband has just been changed to ADSL2+ and now connects with downstream speeds of around 1400 to 1800 kbps. It previously connected at around 6900 to 7200 kbps with ADSL MAX.
I have a BT Home Hub 1.
The current connection stats are below:
|Modulation:||G.992.5 annex A|
|Bandwidth (Up/Down) [kbps/kbps]:||444 / 1,810|
|Data Transferred (Sent/Received) [MB/MB]:||8.51 / 76.25|
|Output Power (Up/Down) [dBm]:||12.0 / 0.0|
|Line Attenuation (Up/Down) [dB]:||24.5 / 40.5|
|SN Margin (Up/Down) [dB]:||21.0 / 32.0|
|Vendor ID (Local/Remote):||TMMB / IFTN|
|Loss of Framing (Local/Remote):||0 / 0|
|Loss of Signal (Local/Remote):||0 / 0|
|Loss of Power (Local/Remote):||0 / 0|
|Loss of Link (Remote):||0|

Hi badger256, Welcome to the Forums.
If you have just been connected, you will be in the 10-day training period.
During this period, your line speed will increase gradually as the MSAN finds the most stable speed for your line - It is perfectly normal.
Give it 10 days and if it hasn't improved, post back 🙂
I hope this helps
My exchange was upgraded about a month ago to adsl2+, my downloadd speed has dropped and fluctuates more..
there are reports on the forum that the HH1 does not work well with adsl2+ ( there are others who say it works fine) I would suggest you try and get another router either by phoning India CS or if you can borrow another router to confirm that is the problem
Thanks for the reply. BT really ought to supply this advice when the line is switched. It's frustrating that the SN margin is set so high initially - it's creeping down now - when the ADSL MAX connection has been stable for nearly 5 years at much higher speeds.
The 10 day period has passed and I still have just a quarter of the downstream speed I had before the ADSL2+ "upgrade" and a very high SN margin. In addition the upstream speed has halved during the supposed training period.
I notice that another poster, 21CENT, had a similar issue fixed by replacement of a HH1 with a HH3.
I've tried the silent line test and it was indeed silent.
as I said already The HH1 is known to have problems with adsl2 and changing the router will help if not solve your speed problem There are other posts similar to yours which were solved by changing the router
This is finally sorted now.
I contacted the mods and my connection was reverted to ADSL MAX. After a couple of days it was again changed to ADSL2+ with similar problems.
I contacted the mods again after the 10 day period had expired and my HH1 was reset remotely and reconnected with a 6.5db noise margin and around 8000kps/1100kbps downstream/upstream speed.
So it seems my HH1 is fine with ADSL2+ it just doesn't work well with the 21CN line noise measuring system.
