Variable Broadband Speed

I have an 8mb BT Broadband connection which most of the time is rock solid at about 6.9mb. In the last two months speed has been variable from 2mb thru to 6mb, even at quiet times of day such as 0600. BT check the line very time I report it and say it's fine.There are periods when browsing when the connection is noticeably slow. Openreach have checked and can't find a fault. I believe it is intermittent. To reduce the identify the problem:

1. I have run speed checks on different devices - same problem.
2. Re cabled the internal telephone (it was noisy) and is now clean.
3. Unplugged all devices bar my PC.
4. Switched off wifi and used Ethernet only.
5. Changed Ethernet adapters in my PC.
6. Swapped by BT homehub 2 for a BT Homehub 5
7. Swapped the older Netgear router that does my internal distribution for a new nighthawk.
8 Checked all network cables properly installed.

All to no avail.

Homehub 5 (DHCP and wifi Off) connected to the nighthawk (fixed IP to HH5, DHCP on for all devices), then to a Netgear GS108Ev2 switch (DHCP off).

I am running out of ideas. Any suggestions?

I should add the thinkbroadband tests which are consistent with bt speedtester often come back highlighting "Variable Speeds".

What line stats does the hub 5 show for your line ? Attenuation, snr, sync and error rate.

Hi Zarjaz, where do I get this information from?

Also worth posting the results link for the speed tests.

The connection speeds if remaining stable may just mean you are seeing the results of contention.

Andrew - I'm new to the forum what's the best way of posting a link?

Mike

Run test then copy the link to this result link eg

http://www.thinkbroadband.com/speedtest/results.html...

Then paste it into the edit box on the forum.

Got it - this was one of the worst results this morning

Have a look here

Looks like contention/congestion rather than a bad line

This has been a continuing problem since November but after checking various routers, homehubs etc.I discovered a lot of network activity with the Netgear Genie application which stays running in the background even when the application is shut down. Having un-installed the application, network speeds appear to have returned to near normal. It appears that it was congestion on my own network and might not have been a BT issue. If others are running Netgear Genie (application not router access screen) it may be worth trying uninstalling it and seeing what happens to speeds.
