No, that's not banding or throttling. You have a v. long line or a fault has developed.

Do you have a record of the stats when you got faster speed?

No sorry don't have stats.

I am thinking the engineer I had here yesterday made a mess of something, the guy turned up without a network lead would you believe so that's the standard of engineer we are dealing with.

Anyway he fitted a new telephone socket, one of them that has the inbuilt connector for the router, I am guessing its not fitted correctly or something.

Prior to his visit I was getting a connection down rate of 8125 although I was only getting a speed of 2mb max when I usually got 7, I can literally throw a stone and hit the exchange, its a 2 min walk

Sounds like you had the amazing Kelly or Quinn out (probably the former) if you had an engineer with no stuff to do the job.

They're a total waste of time in every one of my experiences. They're so bad, that there are a couple of places here that have expressly banned them from attending the sites they own.

Right now. We have an update, Line connection speed is back to normal.

This however is only giving a speed of 0.35

That will be because this looks to be the old IPStream Max service where the throughput takes time to recover after a slow speed event, i.e. you are waiting for the IP Profile to improve

http://www.speedtest.btwholesale.com/PerformanceTester

Should tell you your current IP Profile, will take around an hour to a day to recover.

So looks like what is shown at http://www.coolwebhome.co.uk/faceplate/

In which case probably not the cause and the fact you've had slow speeds before suggests maybe a loose joint in the network outside the home that is intermittently causing a problem.

Don't unplug anything for now, as the BT Wholesale system is looking to see if the line is stable before giving you back some of your speed.

Note the attenuations in the two sets of stats. I would say they point to possibly a complete disconnection of one wire at the time, restored by the time the phone was used.

What was done to fix it?

That's still not banded or throttled. You are getting full whack from your 20CN ADSL Max exchange.

The low throughput must be caused by congestion there. Does it vary at diff times of day?

6am the sync was Downstream 672 (Kbps.)

Also see the attenuations.

Ah yes, good point!
