Just upgraded to ADSL2+

Conrad · Apr 13, 2010, 18:28:05

I have just gone from ADSL Max to ADSL2+ (following a recent 21CN upgrade at my local exchange). Upgrade completed today. Sync is showing as: 834 / 15,889 on my TG585. Is there anything I should be expecting (or anything I should do - router reboot for example)? Speedtest.net is reporting FAR slower downloads now compared to Max - Is this due to another settling in period?

Thanks.

Hi Conrad, our manners seem to have failed us on your previous posts, welcome to the forum.

There is a new training period with ADSL2+ and I think it's simply a case that your profile needs time to catch up. Give it a few days. If you feel there's no improvement then, or want to know anyway, run a BT test, which will report the profile.

Steve · Apr 13, 2010, 18:37:23

I'd be interested to see your IP profile from a BT speedtest too.

Conrad · Apr 13, 2010, 18:55:03

I would like to do the BT speed test (hopefully to see how things improve over the next few days), but I need a "service id" from my ISP. Does anyone know what that would be? Is it just my phone number?

Thanks.

Rik · Apr 13, 2010, 18:57:00

You don't, ignore that field and just put your phone number in. On the second page, enter your idnet username and password.

Results:

Download speedachieved during the test was - 7314 Kbps
For your connection, the acceptable range of speedsis 1000-99999 Kbps.
Additional Information:
Your DSL Connection Rate :15888 Kbps(DOWN-STREAM), 832 Kbps(UP-STREAM)
IP Profile for your line is - 9000 Kbps
The throughput of Best Efforts (BE) classes achieved during the test is - 8.14:39.7:52.16 (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.

Rik · Apr 13, 2010, 19:04:37

Your profile hasn't yet caught up with your sync speed, it will move to 13M eventually. Throughput is slightly low for the profile, if you can try another test in the morning, that will tell us if you've got some exchange congestion going on (I take it no-one else was using the connection at the time of the test?).

Hmmm... hard to say. It is wi-fi'd up with the Wii and laptop also sharing the connection - oh, and also a little WAMP server doing its thing.

Thanks for the Karmas!

Here are the stats from the router. I have no idea if they are any good or not

Rik · Apr 13, 2010, 19:12:36

They look fine to me. You have interleaving on, but that's probably a good thing given the error count, it will add 10-20ms to your ping times, but improve stability.

Conrad · Apr 13, 2010, 19:19:43

Thanks for your help (again) Rik. I'll see if there is anything I can do about those errors and I'll post back in a few days with another speed test.

Rik · Apr 13, 2010, 19:24:19

There's little you can do other to reduce electrical noise on the phone circuit, eg disconnect the ring wire if you haven't already, disconnect your Sky box if you have one (unless you have multiroom), remove any flat extensions in use etc.

Conrad · Apr 13, 2010, 19:43:16

Have just powered down the router, removed an old extension that ran upstairs (no longer in use) and fired the router back up and my sync speed has gone DOWN!?

Stats have remained very similar:

Give it time Conran & things should settle down. Also note you're 'checking' during the exchanges possible congested period.

Conrad · Apr 13, 2010, 22:10:52

Thanks Sobrainy. Just tested again and got:
Download speedachieved during the test was - 8623 Kbps
...which is closer to the 9000 profile. Just need to sit back and wait for the profile to increase now.

Rik, how can you tell whether interleave is on from those stats?

Steve · Apr 13, 2010, 22:16:24

FEC = forward error correction which is part of the interleave process,you find some information here although this relates to adslmax the process is similar i believe.

Rik · Apr 14, 2010, 08:51:49

The other thing, Conrad, is that your re-synced during the evening when noise is on the increase. You'll get a better speed, generally, with a morning resync.

Is it necessary to put in ones password on page 2? I just enter username@idnet.gwx in the first box and nothing in the second. Maybe 21CN is different.

Rik · Apr 14, 2010, 09:30:09

No, you're right, Dave, brain not in gear. It's the username and domain on page 2.

Found you can just paste username@idnet.gwx in the first box and it works.

Rik · Apr 14, 2010, 09:46:02

Even easier.

tehidyman · Apr 14, 2010, 16:28:27

Even Easier still ? I just enter user name without the @etc and it works fine and just phone no. on first page.

Conrad · Apr 15, 2010, 08:57:34

Thanks for the help everyone. Yay!... Profile has gone up to 13000k!

BT Speed test and speedtest.net are showing no speed increase though

Do you think if I power-cycle the router now it will make any difference?

Rik · Apr 15, 2010, 09:36:05

It might, and will do no harm. Aim to do it the morning rather than the evening.

Conrad · Apr 15, 2010, 15:09:59

Performed a few registry tweaks (I have XP) and am now getting much better responses:

I'm happier now!

Now when are they going to let me use Annex M???

Rik · Apr 15, 2010, 15:21:46

I'm not sure. It is on the cards, though. Do you need that much upload speed?

Conrad · Apr 15, 2010, 15:34:13

Not using the upload bandwidth at the moment, but I'm playing with apache (hosting 5 sites right now) and am thinking about setting up mail on the server too. I think having Annex M will give me some breathing room before I splash out on a data-centre solution (or maybe keep it at home with SDSL?).

Rik · Apr 15, 2010, 15:37:51

Can you get SDSL on your exchange?

Conrad · Apr 15, 2010, 15:43:07

I think so (LLU)

Have just checked (samknows) and my exchange is SDSL enabled.

Glenn · Apr 15, 2010, 15:47:50

It would cost a lot to have a SDSL connection http://www.idnet.net/solutions/businesssdsl.jsp

Conrad · Apr 15, 2010, 18:18:49

Ouch! Looks like I will end up going down the VPS route then... Or maybe Co-Lo? I need to check out the prices.

Rik · Apr 15, 2010, 18:24:04

Some of the US hosting systems, eg GoDaddy, can be very cheap.
