Big drop in speed after install

Hi all,

I got BT Infinity installed last Friday and I was predicted to get 37Mbps down and 8Mbps up, however, on install day I managed to get 65Mbps down and 16Mbps up, so much much better than expected!

Over the weekend the speed remained the same until Sunday, where it dropped down by about 9Mbps to 56Mbps

I've now checked again this evening and its now down even more to 45Mbps

Is such a drop in speed normal a few days after install? I know the line is in training mode, but surely a drop of 20Mbps is pretty excessive?

What does the BT speedtester say for your IP profile

When I run the BT speedtester in either Chrome or IE 10 I get the following:

1. Best Effort Test:

Download Speed : 44.69 Mbps

2. Upstream Test:

Upload Speed : 15.41 Mbps


Your speed test has completed and the results are shown above, however during the test an error occurred while trying to retrieve additional details regarding your service. As a result we are unable to determine if the speed you received during the test is acceptable for your service. Please re-run the test if you require this additional information.

That's the beta test. He needs the Diagnostic one, the contents of the results text boxes cut & pasted.

No, I ran the diagnostic test on the left. It doesn't give me my IP Profile and in the paragraph at the bottom explains an error has occurred collecting details.

Describe, if you can, the set up that has been left.

The master socket got moved upstairs to the study using existing CAT5E and thats where the modem and the homehub are sitting.

I've done further speed tests tonight and it seems to be settling at 45/14 now, so it looks like it'll stay around here.
