capped at 40mb?

[angusde]

Hiya, I'm supposedly on the up to 76Mb Infinity2 service.

I was getting a steady 53mb/s before I upgraded in Nov 2012, so was a bit disapointed to get only a slight increase to 59mb/s afterwards, but it is better than most. However, since Aug 2013 it has always tested at 38Mb/s  on SpeedTest.net. The long term graph is telling and the step changes up and then down do suggest that I'm on a 40Mb/s cap?

In reality it doesn't make that much difference, but it does rattle me when I think about it!

Any ideas?

Use this speed tester then carry out the further diagnostics and post back a screen shot of all the results including your IP profile for up and down. If your Up profile is 20Mbps you are in Infinity 2. If the Up profile is 10Mbps you are on Infinity 1.

Here is my BTW test:-

The upload is a bit weird, I tried the test twice, SpeedTest usually puts it around the 10mb mark.

Here is my SpeedTest.net history:

As I said, rock steady 53mb until I upgraded to Infinity2 in Nov2012, then a rather more variable up to 59mb until Aug2013 from where it has been 40mb ever since.

To my untrained eye it looks capped at 40mb, but no idea why? The Infinity 1 @53mb was better than Infinity2 at 40mb?

Weird?!

The picture you have posted is very blurred and I can not see the up IP profile. As I previously said, if it is 10Mbps you will be on Infinity 1 and if it is 20Mbps you will be on Infinity 2. Can you confirm which it is?

You have said you got 53Mbps on Infinity 1, this should not have been possible as Infinity 1 is capped at 38Mbps.

If you were getting 59Mbps and the speed has dropped to 40Mbps it is possible that there is a fault on your line and DLM (Dynamic Line Management) has lowered the speed to maintain a stable connection and will require an engineer to investigate the cause.

Turn your antivirus off while you conduct the test as an download of 53Mbps in Infinity 1 is impossible.

Some AV's skew the test due to cashing. Kaspersky's well known for it in the past (I don't know what it's like now.).

Sorry, my mistake, looking all the way back it must have been April 2012 I switched as it was steady 38mb and then 53-58mb therafter until reverting to what it is now.

I use a work provided Sophos for AV and there isn't a easy way to turn it off short of uninstalling it.

Your up IP profile shows that you are on Infinity 2 so that is not what is causing the slower speeds.

I presume the test was done with an Ethernet connection and not by wireless? If it was wireless you will need to do it wired. 

[angusde]

Yes, it's a ethernet connection.

I've tidyed up my SpeedTest tests and it shows up the step changes rather better.

When I run the BT test, as well as the uploads being really low, the ping latency always tests very high?

The SpeedTest latency has also been rather high at 40-80ms, which I think is worse than you'd expect from a FTTC service?

Can you click on the "Further Diagnostics" button (as shown in you ss) and post the an ss of the result?
