Dropbox have upgraded their systems and introduced different ways of sharing files.

Anyone who tried to use the previous link had to sign in with a Dropbox account. Then, I needed to authorise each request.

The following link is different, and should provide unrestricted view access to everyone.

To get the best out of your line, you need to plug your router into the master socket and add an SSFP filter to it which will then stop the broadband signal going down your telephone extension cables. As already mentioned you do have a bridge tap present, and this is the reason for your slow speeds.

To resolve it, plug the router into the master socket with one of these fitted to what you already have in place https://www.ebay.co.uk/itm/Genuine-BT-Openreach-MK3-...

If your desktop does not have a wireless connection, then you might want to look at either running an ethernet cable from where your master socket & router will be located (master socket location) to your desktop, or if that is going to be a problem, look at getting some power line adaptors.

Totally up to you, but the only real way for you to get the best out of your line is for the filter to be fitted and your router moved to the master socket from the extension socket. If you call OR out, then if everything is ok at the master socket, then you could be looking at a potential charge for the visit, as the problem will be classed as customer cabling (extension sockets).

Hope that helps

Yes, I know they have. IIRC it was to do with security, with the original being too each to hack.

They have changed at least twice. The intermediate one was almost impossible, the latest I have managed to get to work, but more by luck than good judgement.

Anyway, I have now seen yours thanks to your authorising it. It is a bog standard NTE5A for anyone who wants to know.

It is not practicable to site the router permanently by the master socket. However, was able to connect it temporarily to the master socket, where I performed some additional tests. I used an Ethernet wired connection between my computer and the router and I disabled the Wi-Fi adaptor on my computer.

For the first test, I connected the router to the master socket faceplate (i.e. the telephone extensions were still connected to the llne). The router statistics were:

Product name: BT Hub 6A

A Thinkbroadband speed test reported an average download speed of 53.9 Mbps. (https://www.thinkbroadband.com/speedtest/1514809468110844155 ).

Then, I plugged the router into the test socket (with no extensions connected to the line) and repeated the test.

The Thinkbroadband speed test result suggested a slightly slower average download speed of 52.4 Mbps. (https://www.thinkbroadband.com/speedtest/1514810767641781855 )

All of the router statistics were the same, except the Maximum data rate of 22786 / 71933 had increased to 25775 / 82802; the Noise margin had changed from 7.9 dB / 8.8 dB to 16 dB / 11.8 dB; and Line attenuation had reduced from 17 dB to 14.4 dB. Significantly, the Data rate of 19.00 Mbps / 60.00 Mbps remained unchanged.

So plugging the router into the test socket had made little difference.

Finally, I performed a BT Wholesale Broadband Performance Test, which produced the following results:

Download 54.36 Mbps
Upload 15.12 Mbps
Ping Latency 33.13 ms

The test reported a download speed of 54.36 Mbps, which was similar to the results of previous Thinkbroadband speed tests.

You can view the complete result of the BT test at https://www.dropbox.com/s/q440noqxdtkzbz0/www.speedt...

Significantly, the BT test indicates that the IP profile for my line is 55.58 Mbps and the acceptable range of speeds is 40 Mbps to 55.58 Mbps. That differs from the BT offer letter, which stated:

We estimate your download speed will be between 67Mbps and 80Mbps, and your upload speed will be between 19Mbps and 20Mbps.

The minimum guaranteed speed you can expect from your broadband will be 60Mbps.

I wonder whether BT have applied an incorrect profile to my line, because there is no way I could achieve a minimum of 60 Mbps, if the profile is capped at 55.58 Mbps.

From your post ....

"Data rate: 19.00 Mbps / 60.00 Mbps
Maximum data rate: 22786 / 71933
Noise margin: 7.9 dB / 8.8 dB"

Shows that with a DLM reset, and an SSFP on the NTE you could be getting pretty close to 80 meg download sync.

What is capping your throughput speed tests is the IP profile system.
