I don't think there's anything wrong with your link to the exchange, TBH, and I don't see the need for an engineer visit given the above.

I'd still have a look for a test socket, in case the faceplate has become faulty.

Have you also tried a different equipment?

Sorry for asking the obvious.

Matt

I have been known to overlook the obvious in the past

I haven't tried another router but I might have a BT Voyager 2100 knocking around. Would that handle 21CN?

Yes, I'm tending to think it is congestion at the exchange caused by all the little darlings coming home from school after 3:30pm and turning on all the internet connected gadgets they were bought for Christmas.

This crashes the speed for me from around 4000Kbps to three figures every evening and at weekends.

This evening when the speed inevitably dips, I plan to turn off the wireless on the router, reboot it, connect it and it alone to the master socket with and without a filter, (not needed if only the router is attached, I believe?) and connect a netbook directly to the router by ethernet cable.

If the symptoms remain I may have a go with a BT Voyager 2100 if that can handle 21CN.

If that shows the same results and speeds pickup again around midnight I will put it down to exchange bottleneck and await BTs upgrade to fibre which has been promised for our town .......

Is that a plan?

Larry

As others are saying your stats don't look too bad

I don't think you've said who your ISP is yet? Sorry if I've missed it.

Lots of ISPs have capacity issues - more likely than a congested exchange I would have thought. Let us know who you're with and it might shed some light on things.

EDIT: Just read your 'plan' to possibly re-boot this evening. Syncing after dark will always give you a lower connection speed...

you're getting a plain old ADSL1 connection, 21CN or not, so any router will do.

If you're on a business product the contention may go up when you get to the end of the office priority period eg 8pm.

I wouldn't assume it's the exchange, it could be the ISP contention.

No, I didn't name my ISP as I trust them to have done all the checks. They claim not to throttle and I tend to believe them.
They are ADSL24 and they resell Murphx.
The connection has been rock solid over the years I've been with them and although the Entanet days had their moments the throughput was generally good.
I was moved to Murphx a good few months ago and until just after Christmas the new connection has been faster than ever 24/7.
This morning a speedtest gave a down speed of 4.33Mb/s at 9:00am and at 12:00 midday it had dropped to 3.57Mb/s.
The connection never drops and the Up speed and pings stays constant.

I realise that the SN will increase after dark but if I connect at a reasonable speed and achieve a comparable download speed I will feel that I have proved something is amiss with my equipment and within my control.
If the down speed stays drastically below the sync speed then I feel the problem is somewhere beyond my BT phone box.

Thanks for clearing that up. I thought there was some change to the Exchange equipment that allowed the ISP to control much of what BT used to do wrt sync speeds and profiles and that may have changed the modem requirements.

Claiming not to throttle is very different to telling you that they have checked all the links from the exchange to leaving their network (is it just leaving MurphX) and that none of them are getting close to maximum utilisation.

With some links you can see bandwidth reducing even before they hit the maximum in any one direction, i.e. routers can be CPU load limited sometimes, so bandwidth checks look good, but the extra delay in handling packets slows down some protocols. Very old BT Centrals (years ago) used to suffer from this, e.g. would support 120Mbps of traffic, with a nomimal 100Meg downstream capability, but if the upstream hit 40Mbps, then downstream limit would be 80Mbps.

In short its a complex issue, and the evidence you've posted suggests more to do with ISP. What you need to look at now is how other ADSL24 and Murphx customers are doing.

I think as others have covered, router should be fine.

Have you run the second/third BT speedtest? (different login details). This will show if the congestion is within the ISP network, or within the BT network (before it gets to the ISP), i.e congested VP).

The BT test has been a little problematic in that only once has it completed the Up stream test. it usually finishes with -

"Note: An Upstream test was not conducted on this line due to a technical issue. If your concern is related to upstream performance then please retry
the performance test again in 1 hours time."

Only once in the last week has it suggested a further test and it asked for me to change the router login to a different user (BT something or other) and leave the password blank.
However, the router failed to login at all so I couldn't run the test.
