Is this ADSL1 or ADSL2

Other than being SLOOOOW, is this line easily identifiable as ADSL1 or ADSL2+, I ask, as SpeedTest Checkers show the line as being capable of UPTO 2.5MB.

A tiny 'upgrade' to ADSL2+ giving upto 2.5MB would be an absolute godsend, given the user is getting .5MB.

Obviously if the user is currently ADSL2+ then, there's no call to BT to be made!

It's probably ADSL(1). ADSL2 or ADSL2+ would be worse, despite what the estimator says. Has it always been so slow - I see it has been up 13 days?

We could do with the attenuation and noise margin figures. Also for people like me, not familiar with the Home Hub, an indication of which are the upstream and downstream figures. The bandwidth data there could be either way round, depending on the product signed up for.

Is there an easy way to identify attenuation?

This is a farmhouse, so the line is there or thereabouts. It was initially a 512mb line, however ADSL2+ came along last year and I doubt it has been migrated to ADSL2+...

Ah, here we go; the connection is stable, just slooow!

There is a little more speed to be squeezed from the line, by way of having the SNR reset.

What do those same stats look like with the router plugged directly in to NTE test socket, all else disconnected ?

G.992.1 is ADSL(1).

The attenuation figures (signal loss due to distance) are probably higher than reported, as most routers don't give any higher figures than those. ADSL2 (G.992.3) may give a fraction more but I doubt it. ADSL2+ would almost ceratinly be worse at that distance.

The first thing to do if it hasn't already been done is to remove the ring/bell wires. Certainly at the master, and although in theory it doesn't matter - also at every extension socket. Sometimes that has made a difference.

Have a read of the first three and the last pages in this section and see if anything applies as well as the ring/bell wire.

I got delayed while typing - I hadn't seen your post. I forgot that bit as well!

The loss is 61.5 61.3dB down - so that will be an actual figure.

Good point. Though I wonder what one standard deviation is when cheap modems measure it?

Thanks for all your replies folks, I'm no longer at the in laws, however, I'll check these things next time. I know for a fact the Hub is connected via an extension from the mains, so thats the first thing to try.

I also have a different router they can have next time I'm over.

It's all well and good living with sheep, but having next to no internet is painful!

So, we're saying the line is still ADSL1 and that switching to 2+ won't help, or might make things worse?

ADSL2+ will likely increase upload speeds, BUT downstream speeds are not likely to be different and there was a few errors suggesting maybe that ADSL2+ might be more unstable.

Its one of those until you try it you don't really know.

Have you established their exchange is WBC enabled?

Not sure what WBC is, but I got the info via SamKnows;

http://www.samknows.com/broadband/exchange/MRWHA

Exchange name: Whaley Bridge
Exchange code: MRWHA

WBC is ADSL2+ service from BT Wholesale, which means BT Total, Plusnet, Zen, IDNet and others.

The exchange also offers ADSL2+ from Sky and TalkTalk using their own hardware

My line stuck on ADSL(1) when I was first activated. I reported it via the BT forums which seems to get more positive results than phoning.

It took a few days but then it switched to ADSL2+. My upstream speed went from 448 to 588 but downstream didn't change.

Funnily enough, the downstream SNR seemed more stable but upstream was a bit more spiky. After a further few day, the downstream SNR automatically changed to 3dB (from 6dB) and the downstream speed changed from 5,400 ish to 6,203. Has been running for 25 days since - SNR now clinging on at 2dB ! On ADSL(1), I was lucky if I got 2 days uptime.

As you say, always worth a try.

I would expect ADSL2 to be worth 500k extra downstream, through a lower SNR margin would be worth a bit more.
