Speed locked at 40mbps!

Paying for 80mbps on Infinty 2 package, but BT wholesale speed tester says maximum speed 44mbps is achievable.

Any thought on why this is happening. First two weeks we were getting 70mbps. then it dropped!

Cheers!

Disconnections

Please explain, thanks

Stats would help

Sorry, dont know how to find them, please may you tell me where to find them, thanks

If you're using the Homehub 5, you will find them in Troubleshooting > Helpdesk on the web GUI.

DSL uptime: 1 days, 19:25:10
6. Data rate: 11782 / 45986
7. Maximum data rate: 11726 / 46434
8. Noise margin: 6.0 / 6.7
9. Line attenuation: 15.0 / 12.7
10. Signal attenuation: 15.0 / 12.9
11. Data sent/received: 1.5 GB / 5.6 GB#

Is that enough?

That's really low attenuation which should be good for full speed. I see the noise margin is above the target of 6 which indicates DLM has capped your line due to disconnections, in order to raise the noise margin to give your connection more resilience to noise.

Was this an engineer install or a self-install?

Is the modem connected to the master socket?

Do you have any extension wiring?

Well,

we had a Openreach engineer install the router, and he ran all the tests, with the results all positive

Our router is the BT Hub5 so no modem

The router is plugged into the master socket

cheers

Any phone extensions?

Is that a HH5 type A ?

says BT Hub 5A

we have two phone lines. One for the broadband and the other for telephone

Ok. What I'm getting at is that you may have a noisy line which is often caused by poor extension wiring or a line fault. It sounds like you may not have any extension wiring so you should report the problem and get an engineer to visit and find and fix the fault.

Be aware that if the problem is due to your wiring you may be charged £150 by BT.
