The test results and stats and IP profile are much the same as the set you posted last Saturday.

When putting your stats into MrSaffron's ADSL and ADSL2+ line speed calculator,

http://www.coolwebhome.co.uk/calc/index.php?param=RG...

The result suggests you could get better throughput speeds.

Any signs of congestion when you do a ttb speed test?

The router is always used wired, yes?

As mentioned earlier by kasg, the throughput speed is pretty much what would be expected.

In reply to a post by kasg:

OK, that all confirms that the download speed you are getting is what you would expect from your IP profile (which is derived from your sync speed) so the question is why has it reduced?

It's not going to improve noticably without without an improvement in sync speed.

Thanks John, those stats are just what was required. If you know what the connection uptime was for them, that would be helpful.

The current sync speed is rather disappointing for your line attenuation. Because the SNRM figures are close to 6dB it all suggests that there maybe some sort of interference present. What is slightly concerning is that the stats are showing CRC & FEC errors on the Upstream but not on the DS. I'm not familiar with this ASUS and did wonder if it was misreporting the US and DS errors the wrong way round - other modem/routers have done similar in the past, but it's not common these days.

Leaving that aside, the slight hum on speakerphone might be due to the extra gain in that mode, but it might also be due to slight line imbalance (due to a line fault) - the latter can make the line vulnerable to increased interference pickup. As you've reported a fault to Plusnet, when they pick it up in a couple of days they should run a Copper Line Test (CLT) which might identify any line issues. If they do so your connection will drop for just under 3 minutes whilst the test is conducted (Is your line rental with Plusnet?).

The other things worth checking, is your phone a cordless one?
Is your filter what called a rat's tail type, see this?

If the answer is yes to both, do you have a spare filter? If so, unplug the phone from the first filter (leave the modem/router connected to the first one), plug the 2nd filter into the first and then plug the phone into the second filter. This "double filters" the phone. Some cordless phones can give some interference that affects the line and this can often cure it.
If you do that, then post some new stats.

If the phone isn't cordless, don't bother with the above.

Chris,
Thanks for the advice and info, yes my phone is cordless and I will try the double filter but the wiring has not changed from 2007 and in February 2015 I was getting 7.51 Mbps so why the change now. I will have a go at the added filter tomorrow when I am fresher and let you know if there is any improvement.
The line check will I hope show any problem.
John

"so why the change now?" - Not an easy one to answer.
It's not just wiring changes that can cause this sort of situation. The simple answer is something has developed a fault - a rather uninformative comment!! From the speedtest results you've posted, it's fairly clear things went downhill quite rapidly. The trick is to look for obvious things and also eliminate as much as possible.

The usual first step is to see if there's any discernible problems with the phone line - any strange noises, problem with incoming or outgoing calls. Some line faults won't always display in that manner. Stats can sometimes give an obvious indication - for example low speed, high SNRM could indicate there's been a burst of interference, static (lightning) or line noise and a controlled resync returns things to normal. Error figures will also help build a picture of what may be happening.

If a user had extension sockets and wiring, plugging into the test socket eliminates that where the wiring might have developed faults or be picking up interference.
When a problem still exists when connected to the test socket, the possible cause can be divided into 3 categories.
Own equipment fault - Modem/Router or Filter, Line fault, or sources of Interference - which may be internal or external.
The double filtering of the cordless phone is a quick easy thing to do, usually without losing sync and depending on any changes to the stats, may give an indication of the first filter being faulty or the cordless phone generating interference because it's developed a fault.

A remote CLT will usually find most line faults, but whilst awaiting that, then the next step would be to try another modem/router. Plusnet's broadband checks on the xDSL Status, the Radius log and WBC Line Profile could also give clues as to what's happened. If all that fails to identify anything, then more detailed checks are going to be needed to look for sources of interference.

Having said all the above, I should have remarked on the DS sync speed in your stats. That looks like it could well be a banded speed. DLM (automatic exchange Dynamic Line Management) may have acted in response to multiple connection drops/resyncs, the cause of which may not be obvious at this point. The speed test results suggest that this may have happened during the last week of January.
If there's been several losses of sync, there's usually loss of PPP session and this will show clearly in the Radius log. If this is no longer happening and the line appears stable, then Plusnet may just try an SNR Reset if no other faults are showing.

In the meantime keep an eye on your sync speeds, but especially the modem/router connection Uptime, your IP Address to see if it changes (but don't post the address) and which Gateway you are on - the latter two usually change as well, if you get a connection resync.

Plusnet reset my line on the 18th February 2016 and said to wait three days for the connection speed to settle down to my new IP Profile BT test of - 8.76 Mbps.
No increase of speed after three days.
My router was showing Data Rate Up: 1064 and Data Rate Down: 9928 on the 18th.
Decided to switch off the router on Sunday 21st Feb as I had nothing to loose and low and behold an improvement on my connection speed, looks like my problem is solved with a line and router reset.
I did try the Speed at Ookla today and got 8.48 Mb/s down 0.90 Mb/s up

Thanks for your advice and interest, until the next time.

Hi John,
well I'm glad you've got an improvement. Did Plusnet do a CLT? I hope there aren't any residual line issues that cause problems in the future.

When you've had an improvement in sync speed, and hence BT IP Profile, but no increase in throughput speed, always check your Current Line speed (Login required) first. If that's not gone up to match the IP Profile then nudge Plusnet. If it's gone up it usually drops the PPP Internet session so that the new profile takes effect.

Sometimes that PPP drop doesn't happen and so you need to do it yourself.
Clearly a reboot of the modem/router will cause this, but it also causes loss of sync on ADSL and that is not generally a good idea on longer lines especially if at the time your SNRM has dropped a bit below the current Target (for example during dusk to daylight when increased noise often affects the connection) you'll then get a slower sync speed.

To just drop the PPP Internet session on Plusnet Modem/Routers (and many others but not all), you log into the modem/router and find the Disconnect button, click it, wait 30 seconds and then click Connect.
If you have the 2704n, the button is on the Homepage in the Connection Status - Internet Status line. If you have a TG582n, it's in the Internet box.
HTH.
