Unsure if I'm on ADSL2+ or not

[fetler]

Hi all,

I apologise in advance for what may be an utterly stupid question, but how can I find out if I'm on ADSL2+ or not? I'm currently having major problems with what may or may not be my Netgear DGN1000 router (the connection keeps dropping every 10-15 minutes for a few minutes), and I don't actually know what I'm on.

My line stats are:
Connection speed:
Downstream 7064 kbps
Upstream 1068 kbps

Line attenuation:
Downstream 39.4 dB
Upstream 23.5 dB

Noise margin:
Downstream 8.4 dB
Upstream 5.3 dB

Thanks,
Matt

Hi Matt,

I'm sure one of our more knowledgeable people will be able to have a good guess at what you're on from your stats, but in the meantime, I think it should give you a clue if you login to your IDNet customer portal and check your Package details:

Thanks Simon, but unfortunately it doesn't appear to say, unless I'm missing something!

The 'Your Package' link should tell you.  What does it say? 

[fetler]

It says:

Package: Pro
Bandwidth Allowance: 100GB
Package Monthly Cost: £25.80 (£21.50 ex vat)
(Note: this is the standard cost of package you are on.)

OK, it may be because the old ADSL Max service is no longer available since the new packages were introduced, so you're probably on ADSL2+, but it's possible you still may be on your original Max profile.  Have you contacted IDNet about your issue?

[fetler]

Thanks Simon, I've raised the issue with IDNet and they say I'm on ADSL2, not ADSL2+. They've advised me to keep it plugged in to the test socket for the time being to stabilise the speed.

There's no such thing as an ADSL2 product, it's either on ADSL1 or ADSL2+. What CAN happen is that if your line is not very good, and you're on an ADSL2+ connection, the exchange will attempt to use ADSL2 instead to stabilise the line at a lower speed. ADSL2 just doesn't use some of the higher frequencies available on ADSL2+.

[fetler]

Ahh their tech support have since told me they meant to say ADSL2+ 

[MisterW]

I'm not familiar with the DGN1000 but you may be able to tell exactly from a detailed ADSL status screen. ADSL1 is G.995.1, ADSL2 is G.995.3 and ADSL2+ is G.995.5.

I've just noticed that from your stats, you have an 'uncapped' upstream, did you specifically request/need that ?
The reason being that a higher upstream speed can sometimes affect the downstream speed. Also with the higher upstream speed comes a lower SNR on the upstream and makes it more susceptible to resynching due to line noise. Capping the upstream at 448k may improve the stability a little.

If interleaving is applied to the upstream that would cap it at 888Kbps on adsl2+ his line could be remodulated to an adsl1 profile to give more stability. The super Stable profile might help but that will increase latency and snr with to many disconnects more rapidly than the standard stable profile, also lines don't always have DLM switched on to auto, in this case that would help. I'm surprised his speeds are so low tbh, his attenuation is 39.4db mine is 33.5db and I sync at 14496Kbps, even with the snr he has he should be going faster unless the line is very degraded or he has cabling/router/noise issues I would have thought.
