I'm hopeful. Take a look at the stats late evening (without rebooting).

As your router is still basically a Speed touch it's possible to put the stats into the old Be stats analysis page after a little reformatting - I added spaces after the

and reversed the decimals and commas back to UK style...

It had this to say...

Expected download speed at your current sync rate: 483.40 KB per second (or 3867 kbit)

Expected upload speed at your current sync rate: 47.66 KB per second (or 381 kbit)

Problem: Downstream sync speed of 4544 kbit is 2952 kbit slower or 61 percent of the average for connections with the same downstream attenuation of 42dB.

Problem: Output power down (19.9dBm) is very high. Most common values are 17 to 19.5dBm.

Problem: Resubmit statistics in at least 2.08 hours. Ideally more time is needed to say whether any errors were just one-off occurrences.

The downstream sync is low because of the elevated target margin you have currently.

Looks like a pretty normal evening drop in noise margin now - not dropping from ~ 9dB to -2dB.

I think the original issue was poor filtering of the alarm system which the faceplate will have fixed. You were lucky that the alarm installer used the faceplate and didn't just wire it directly to the master socket rear which some do (contrary to BT regulations).

The new router seems to manage a higher sync despite the increased margin caused by not shutting the router down before disturbing the wiring (just yanking the connector out can lead to this).

You can either call the ISP, use their forum, or just wait for the target margin to return to the default 6dB which will give you a better speed.

If you do see another connection reset check those stats - I'd expect to see Loss of Signal (Local/Remote):1 / - to have increased.

If you get a connection reset and no change in loss of signal then it could be the WiFi or something else entirely I suppose but at least your internet connection appears to have been sorted out.

If it has resynced then at least your setup is as good as you can make it and you can start to consider the possibility of a line fault and callout without risk of them blaming the alarm and charging a fortune.

Many thanks for all your help - much appreciated :beer:

This morning I got this from Plusnet:-
I've arranged for the line to be reset. The reset normally takes 4 hours to complete. After 4 hours your router will need to be powered off for 10 seconds and then turned back on. When it reconnects we'd expect the speed to be normal again, but it can take 24 hours before everything fully updates. As part of resetting your line, this also starts a fresh training period on the line. This lasts for 10 days and you may see your speeds vary a little as the line tries to work out the best balance between speed and reliability for you. You may even see that your broadband connection drops a little over this period, but this is perfectly normal. Whilst in this training period, please make sure that your router stays plugged in and powered up continuously. If you don't then you will receive a slower speed than your line may have been able to support.

So - that was at 8am, so I rebooted the router at 1pm and now we have this ...

as well as this

Not a very high U/L, but the D/L is about double what it was!!

This is what the Be stats analyser had to say...

Expected download speed at your current sync rate: 626.38 KB per second (or 5011 kbit)

Expected upload speed at your current sync rate: 47.66 KB per second (or 381 kbit)

Problem: Downstream sync speed of 5888 kbit is 1608 kbit slower or 79 percent of the average for connections with the same downstream attenuation of 42dB.

Problem: I need an Uptime value in order to give an idea of whether your statistics are okay or bad.

Problem: Output power down (19.9dBm) is very high. Most common values are 17 to 19.5dBm.

Problem: Signal Noise Margin Up (22dB) is higher than average and may be this high in order to compensate for current/previous high error rates.

Problem: There are some FEC Up errors. FEC errors are *corrected* errors, so these are probably nothing to worry about. Speedtouch routers have a habit of misreporting FEC errors anyway.

The speed comments are now pretty inappropriate as Be were LLU providers using ADSL2+ and you are on bog standard ADSL.

ADSL2+ would sync a little faster and LLU isn't governed by the BT Bras profile which allocates downstream speed in 512Kb bands rather than as much as the sync can truly support - http://www.kitz.co.uk/adsl/IPprofile.htm give a pretty full explanation of that. With that sync you can get 5Mbps and after overheads are taken into account you are pretty much spot on.

The sync itself is close to what the Kitz estimator suggests you should get.

Forget the output power comment - that's outside your control anyway.

Forget the upstream noise margin comment - that's beause you are on plain ADSL

The errors comment you already know about.

So Looking about right - lets hope it stays that way.

J_B · 11 February 2015 at 5:43PM

Thanks

We are not LLU here, so choice is somewhat limited to ISP's, but have been a happy Plusnet customer for 7 (?) years.

I asked plusnet for an explanation as to why the D/L was nearly 10 times the U/L speed and they replied ...

The reason for the upload speed is that the equipment in the exchange is still the older ADSL1 technology and as such upload is capped at 448Kbps MAX.

..and they are not being dishonest. That is true.
