Ultra Slow Infinity

Question

Hi
I have had Infinity Option 2 since April, and when it was first installed I got 37mb download and 8-9mb upload, however over time it slowed right down, but a reboot of the router and hub would usually restore the speed.  Over the past month, the download speed has decreased steadily, and the upload speed has reduced to at best 3.98mb, but more often than not is less than 1mb.  Over the past fortnight or so, there has been a significant drop in speed, both up and down (see the attached graph)  Tonight, I have an download speed of 0.72Mbps and an upload speed of 0.21Mbps.  Any suggestions as to why this is happening and how I can get back to the origional speeds I had?
Regards
Trevor

Hi Trevor and welcome.
What I would do first is....
Connect your laptop to the HH3 via an ethernet lead and run the FTTC diagnostic part of the speed test http://www.speedtester.bt.com/
And note your IP settings. 
Being wired this removes any possible wireless issues and will give you your IP Internet Profile which will be useful if you have to contact the Forum Mods for help.
The IP is the profile setting the exchange has set you on to provide a reliable broadband.
If your IP settings are low with resulting download achieved speeds you could try forcing an IP reset.
Turn off both the Openreach Modem and HH3 and after a minute or two back on again.
You then need to run the BT speedtester again to see if the IP has changed.
(However there is a 1 hour delay between tests) 
You could try the BT Beta 40Mbps test part as that may not need the 1 hour delay.
Or in the meantime try the http://www.speedtest.net/ and see if speeds have improved.
One variation of speed problem is when the IP setting drops very low and the achieved download is correspondingly low.
The other variation of speed problem could be the IP setting remain high (eg 38716Kbps) but the achieved download speed is very low.
Carry out these tests and add the results to your thread, if things have not improved I would seek help from the BT forum Mods with this form http://bt.custhelp.com/app/contact_email/c/4951
And add a copy of this threads URL to the contact form so they can see the background to the problem.
The Mods are very helpful and will contact you, may take 72hrs or so due their workload.
Btw it's best not to turn off the BT Openreach White Modem too often as this may be recognised as a line problem by the DLM Exchange Monitoring equipment with a corresponding reduction in IP (speed).
Good Luck 
My test result example below shows 
IP Profile for your line is -38717 Kbps.... 38Mbps download max speed setting.
Upstream Rate IP profile on your line is - 2000 Kbps.... Upload capped at 2Mbps as I am on Infinity option 1.
Test1 comprises of two tests
1. Best Effort Test:  -provides background information.
Download Speed
33735 Kbps
0 Kbps
38717 Kbps
Max Achievable Speed
> Download speedachieved during the test was - 33735 Kbps
 For your connection, the acceptable range of speedsis 12000-38717 Kbps .
 Additional Information:
 IP Profile for your line is -38717 Kbps
2. Upstream Test:  -provides background information.
Upload Speed
1550 Kbps
0 Kbps
2000 Kbps
Max Achievable Speed
>Upload speed achieved during the test was - 1550 Kbps
 Additional Information:
 Upstream Rate IP profile on your line is - 2000 Kbps
