Re: BT dropping minimum guaranteed speed half way through contract.

Thanks for all your help everyone. I have unplugged the powerline plugs as a test. Will try and update this post in a week or two and let you know if the IP profile increases at all.

Re: BT dropping minimum guaranteed speed half way through contract.

The best test of all is to connect your kit to the test socket by removing the faceplate from your master socket. This will rule out all internal telephone wiring, which is usually the number 1 culprit.

Re: BT dropping minimum guaranteed speed half way through contract.

Ok so I think I will go your route first, I have taken off the faceplate and connected a micro filter to the test socket, got the telephone and home hub plugged into it. I have left the powerline plugs turned on and connected.

 

Strangely I just did the BTW performance test and the IP Profile has gone up by 1mb. I will keep checking over the next week or so and write back.

The downstream IP profile is a set percentage of the downstream connection speed (stats line 6 data rate).

If you re-connect it can connect at a slightly different speed depending on the noise at that time of day and wiring set up.

 

Check the connection speeds (data rates) in the HomeHub stats. As I mentioned before, those are what any estimates and guarantees are actually referring to. They also only relate to the connection speeds at the test socket as BT don't have any control over home extensions.

... and strictly speaking according to others who have posted before, the BT Wholesale estimates are actually for the connection speed at the distribution point (such as the pole your house is connected to). That suggests that if you have a very long and/or dodgy cable from the distribution point to your house then the estimates might be way out.

 

However, the fact that you originally got much faster speeds implies this is not a factor for your line?

I certainly wouldn't suggest trying to place your HomeHub on the top of the telegrapgh pole. Smiley LOL

The wireless signal would be rubbish in your house!

Re: BT dropping minimum guaranteed speed half way through contract.

haha, yeah we had 80-85mb when it was first installed and I guess over the last year it has just been going down and down. Could be because more people in the street now have fiber or could be a fault/dodgy wires.

Re: BT dropping minimum guaranteed speed half way through contract.

Could anyone let me know if the below result means something different? I only ask because at the bottom it says "The test result has indicated that you should contact your ISP for further assistance." does this mean there is an actual fault on the line? It's weird that it has the range of speed backwards like 60 Mbps-60.31 Mbps . and the line is red.

Re: BT dropping minimum guaranteed speed half way through contract.

I suspect that's just a bug with the speedtester. It should not be indicating RED at those speeds.

Re: BT dropping minimum guaranteed speed half way through contract.

The range is shown the nornal way round in that last test (low - high).

It seems that the system has a target low (the first figure) that I assume is based on either estimates or previous actuals for the line. If the IP profile drops below this low then the range is listed back to front (low - even lower).

I think the red colour is because the actual download speed achieved is below this low figure (60Mbps in your last example case).

Note that this situation is often seen with a low that's a round number such as 20, 40 or 60. This implies some sort of classification of the line into a band with a minimum low is happening in certain circumstances?
