I do believe the errored secs are from where the Internet light on the Hub went out for about half a minute, this was right after it came online for the first time and haven't seen it do that since

It's really confusing, this underperformance :S But hey, this is the fastest home broadband I've ever used so..

Okay, that is possible.

I think the best thing you can do for now is monitor that line... And hopefully get SNRm down and interleaving switched off.   We need to ensure it's stable though first.  Strictly speaking it should be capable of more... But we need to see what's gong on first and a period of time with RouterStats should help us in this respect.

Unfortunately Router Stats isn't compatible with the Home Hub 3

Not even the Lite version?    (How I detest that American spelling.    )

[kitz]

Unfortunately it would appear it doesn't.   May be worth trying this suggestion for the v2.

Alternatively, use a router that works with routerstats.?

[matthewcl375]

That doesn't seem to work  Oh well...

Had a couple of re-syncs so far, these are my current stats, as can be seen upstream sync has improved quite a bit, but looks like some Downstream sync has been sacrificed in the process:

   
ADSL Line Status

Connection Information

Line state:   Connected
Connection time:   0 days, 00:10:41
Downstream:   15.99 Mbps
Upstream:   1.13 Mbps

VPI/VCI:   0/38
Type:   PPPoA
Modulation:   G.992.5 Annex A
Latency type:   Interleaved
Noise margin (Down/Up):   9.0 dB / 6.2 dB
Line attenuation (Down/Up):   6.2 dB / 3.3 dB
Output power (Down/Up):   20.1 dBm / 11.5 dBm

these are my current stats, as can be seen upstream sync has improved quite a bit, but looks like some Downstream sync has been sacrificed in the process:

Upstream and downstream have completely separated frequencies (subchannels), so each channel ( ie up/down) dont encroach on each other and are independent.  Its only when moving to annex_M that downstream is sacrificed for upstream.

Your upstream power has now slightly increased which is why you are possibly getting the higher upstream.
As regards to downstream, its normal for it to fluctuate during the course of the day...  because SNR fluctuates.  This is normal and to be expected.   You could sync at say mid-day and then try a re-sync a few minutes later and it will be different.   It is very seldom that your downstream sync will ever be exactly the same.

It may aid understanding to read How to interpret your adsl line stats.  In particular:-

  ~ What is SNR?
~ What is SNR Margin?
~ What is Target SNR Margin?

There does appear to be something a tad weird going on with that line because it doesnt appear to be performing to full potential yet...  However its still within the training phase and could settle down... and you should give it time to do so.

If it was me, Id personally be swapping the router for one that works with Routerstats, RS-W, or DMT tool.

[matthewcl375]

I also noted that the Target SNR Margin upstream has been pulled down to 6db now, no idea why the DLM can't do the same for downstream and give me a better sync

Yeah easier said than done in my case since I don't own the router or pay for the broadband

I wasn't aware that you weren't the account holder. 

What about the router you used on tesco net, and iirc you did have another router too.  I can't recall now what these were as this is a quick reply before bed.  What were these and can they be used to get some decent monitoring.

[matthewcl375]

Nearly off to bed myself 

Errm I have the router from Tesco, the TG582n, which worked fine Broadband-wise, apart from the occassional reboot when things got a bit too hot to handle

The only other one is the BT Home Hub 1, which is pretty much useless broadband-wise, last time I plugged it in it gave a crappy sync and forced my IP Profile down to 4.5Mbps 

[kitz]

The tg582n should work fine on adsl2+.  I use one myself as I find it stable with good sync rates for a short line.  It also works fine with routerstats.  I stand mine on its side and it keeps reasonably cool.

The 2wire home hubs on the other hand - whilst they seem to be very good on long lines - from my own experience are not so good for short lines 

[burakkucat]

Just thinking 'out loud', atm . . . an Huawei HG612, unlocked with the Asbo-firmware, connected to a Beattie HH3.0 should allow even the most obsessive Eagle to gather an over-abundance of line statistics. 

[matthewcl375]

I'd like to try the tg582n on this connection, but I think it would be best to leave it till the end of the 10 day training before plugging it in, you know just in case it makes the sync plummet or some other oddity 

[matthewcl375]

Well, I've been put on fast path, let's see how it turns out:
