Re: How accurate are speeds on dslchecker.bt.com?


[re: arronlowley] [link to this post]
 
At 440m I am currently at 72Mbps sync ... and if one noisy neighbour turns their connection off I can get nearer 75Mbps. The 72 sync gives around 65 or 66 actual

So at 470 metres over 60Mbps can be achieved.


edit to add:

Have just run up DSL stats and it is showing max achievable of 79272 kbps and an SNR of 4.2 ... looks as though the low SNR trial has been expanded or is rolling out.

I'm not sure 4.2 proves anything, I have often had it that low for several years. Currently on 5 but it was 4.8 when I looked a few minutes ago.

Mine has been sitting at 6.1 for a long time and rarely moved more than 0.1 ... there was a 10 minute loss of sync at around 1:00 AM on Thursday. The line is now synced at 79.3Mbps and speedtests are up at 74Mbps.

If that is the case, then how can my line stats be explained?

Power outage for the whole cab and you synced as one of the first with a 6db. More subscribers come online and your snr drops?

Though, to be fair, when that happens, the reduction in SNRM goes hand-in-hand with a reduction in the max attainable figure too.

Usually, anyway.

Best way to figure out the current target - do a manual power cycle, and see what the outcome is.

I'm still on ADSL2 and about a mile from my fibre cabinet by road.

A few months ago, the checker was showing a clean high downstream of 16.5 Mbps but since then, it's dropped to 5 (the speed I'm on at the moment).

Does anyone know what's caused this large decrease?

Is it likely to go back up to 16.5 or stay on 5?

Thanks.

Try re-syncing to the DSLAM and see what happens.

Was this a new cabinet when you checked the first time?
