BT Infinity 2 - Download Speed Suddenly Slow

We've had BT Infinity 2 for quite a while now but suddenly after around the 25th the download speed has dropped dramatically.

 

We were getting around 45Mbps download and 12Mbps upload before on both BT tests and http://speedtest.net/ tests which are also very accurate.

In real world situations when downloading things, each device could reach about 5 - 6 Mbps.

 

But now it has just completely dropped!

Tests now range from 4Mbps download to 20Mbps download compared to the much better 45Mbps and upload ranges from 8 to 10 Mbps!

 

And in real world situations each device can only reach about 0.3 to 1.8 Mbps maximum which is no good for downloading or streaming anything!

 

None of the devices have viruses and I've done everything suggested on the MyBT page about it and there is no improvement...

Tests were all done on a wired connection.

 

Any ideas?

Re: BT Infinity 2 - Download Speed Suddenly Slow

Can you run btspeedtester again but this time run the diagnostic test when first test completes and post the results

 

if you have a hh5 go to troubleshooting then helpdesk and post stats 1-12

Re: BT Infinity 2 - Download Speed Suddenly Slow

Nothing wrong with your connection according to that. Your speed appears to be throttled by congestion or because there's some football on BT TV tonight

Can you run this speedtest and post the graph please? http://labs.thinkbroadband.com/ispa/

It can't be congestion as it's been this bad consistently for around 5 days now...

Re: BT Infinity 2 - Download Speed Suddenly Slow

Are you doing the tests while wirelessly connected to the HH5?

 

If so, can you test using an Ethernet cable connected to the HH5 instead?  It's not a line issue.
