New down speed problems advice gratefully received

Sorry for typos and misspellings I am dislexic

I have posted here before regarding speed problems and may people were very helpful. Then I had regras0ded to the 80Mb service and after getting Openreach in my down speed was settled around the high 40’s.


Then in mid-July my speed dropped to the near same down speed I was on before the 80Mb regrade, high 30’s.


My ISP Eclipse has not been very helpful, a support person did as line test said it was a fault on our side and grudgingly arranged another Openreach call out. After a lot of promises of how much we would have to pay. As nothing had changed on our side of the BT master socket that didn’t worry me. Since the visit I have changed the lead between modem and master socket, no change at all. The engineer checked the line, implied there was a line problem and they would change my line in the next few weeks. He also felt I wouldn’t notice any real difference between the speed I was on (and what I was paying for).
Latter Eclipse said they had been told there was some A5 work needed. They since asked me if I had any updates, bit off how was I meant to know what they should be finding out/doing!
I did a BT test yesterday showing no change in the morning and sent it to Eclipse who closed the ticket after getting the update. Not surprisingly I have sent a strong protest at this action and a demand they do something.

I ran two tests to day with a reboot of the modem between them and the results are
This morning

Download speed achieved during the test was 39.13 Mbps
For your connection, the acceptable range of speeds is 40 - 73.4 Mbps
IP Profile for your line is 73.4 Mbps
39.13 Mbps
73.4 Mbps
Upload Test
Upload speed achieved during the test was 15.32 Mbps
IP Profile for your line is 20 Mbps

This afternoon
BT Test this afternoon
Download speed achieved during the test was 38.79 Mbps
For your connection, the acceptable range of speeds is 40 - 61.63 Mbps
IP Profile for your line is 61.63 Mbps
38.79 Mbps
61.63 Mbps
Upload Test
Upload speed achieved during the test was 18.02 Mbps
IP Profile for your line is 20 Mbps
This is well below the speed given by Broadband Availability Checker which has actually increased in claimed impacted speed since I regraded to now claiming between 80 to 62 and a handback of 55 which is above what I am getting at my best speed.

My modem is a Vigor 130 and after the beboot is saying
Connected : Down Stream : 63667Kbps / Up Stream : 20000Kbps SNR Upstream 6 (dB) SNR Downstream 6 (dB)

I would be very grateful of any advice as to what to do now as clearly I have a problem with both Eclipse and Openreach not dealing with the drop of speed.

So your sync currently is 63667Kbps / Up Stream : 20000Kbps and what was a speed test like when you had that sync?

I hope I understand what you whant
A test just done is



In July this was more the speed


For a time after the 80/20 regrade BT and Speedtest were both about 48/9 until late July it went down to 39.

Are you testing throughput speeds (speedtests) connected wirelessly to your router, or through an ethernet connection? A wireless connection cannot be relied on. It has to be through ethernet to the router.

38 Mbps download when sync is 63 Mbps suggests a throughput rather than Openreach issue

The tests are ethernet.
The setup is a BT master socket (NTE5C) on one side off a wall using the cable supplied with the modem on the other side of the wall. Master router next to modem with two other routers Ethernet linked in other parts of the house. None of this(except trying a different cable between modem and master socket (which made no difference) has changed in the period of a drop of about 10Mb speed down with no real change to the up.

Soprry I am not cleare what "38 Mbps download when sync is 63 Mbps suggests a throughput rather than Openreach issue" means.

I have conexted the laptop direct to the base router and no diffrence

Sync is the speed your router is connected to the equipment in the Openreach cabinet. 63 is very good. The speed you are getting from the internet, and the TBB speed tester, is much lower. The difference is something your Internet Provider can control. Some providers have their own profiles that limit the speeds, even if you are connected faster to the cabinet.

Only your ISP can fix this.

Three routers on the circuit? How many have DHCP enabled, how many with firewalls enabled?

Quite apart from that, I fear the problem is likely to be explained by this thread. Quite in what way I'm too tired to work out.

Three routers on the circuit? How many have DHCP enabled, how many with firewalls enabled?

One room in an extension with exterior wall between there and rest of house. Set up as a AiMesh so only base runs firewall. If I could get the silly L shaped power connecter out of a small hole I would get rid of one now I have been allowed to add a router in the living room to provide good wi fi connection to a upstairs work room

So if I get this right if the BT gear cane talk to my modem at the speed its sicing at there isn't a problem with the connection just something (my ISP) restricting what actually gets through. This would explaign why the Openreach engineer said he didn’t think changing lines would do anything though why he didn’t just say I was being throttled?
