Infinity 2 speed frustrations

Back in early July, we made use of our "personal offer" to upgrade from Infinity 1 to Infinity 2, more than anything because we were offered a promo price of £14pcm for 24 months and our Infinity 1 was going to increase from the setup promo of £10pcm to ~£25pcm.

However, our sync speeds (especially download) are worse than they were before the transition!

Before the transition, we were getting ~23Mbps sync, but now it is syncing at ~18Mbps.

Router (HH5) stats from a reboot in the last 30mins...

1. Product Name: HomeHub5
2. Serial number: +076286+1516001119
3. Firmware version: v0.07.05.0A13-BT (Type B) Last updated 9/12/2015
4. Board version: 01
5. VDSL uptime: 0 days, 00:21:36
6. Data Rate: 4486 / 18000
7. Maximum Data Rate: 4557 / 29237
8. Noise Margin: 6.2 / 10.1
9. Line Attenuation: 40.1 / 25.2

For a short period around August, our sync speed increased to ~23Mbps and I noticed the download noise margin at that time was ~6.1, but it now seems common to see it at 10+.

The BT online fault checker is useless, it thinks my line is good with a ~16.5Mbps speed test, on a product that is capable of supporting over 70Mbps in better circumstances.

Whats more, our initial e-mail for Infinity 2 stated a minimum guaranteed speed of 20000Kbps, which we are clearly not getting.

Our flat (same one for ~10 years) has never been great for broadband, apparently there is some sort of "star" wiring in the loft. It was only when Infinity 1 was installed that the old basic telephone socket was replaced by engineers and at the same time, they disconnected the unused extension to another ancient BT socket.

I'm clueless about what to do, it is complicated by we hope to move before next summer, where there is a good chance our Infinity 2 package will work much better due to better internal wiring and perhaps closer to the cabinet.

But right now, for the sync speeds we are getting, we might as well be on the basic BT non-fibre package that is up to 17Mbps and £7pcm in the current promo that ends later today.

I'm starting to think I should have thought more seriously about Virgin, there is a completely separate "Cable & Wireless"(?) phone socket in the lounge, which I presume would completely by-pass that mess in the loft (no ring tone if phone connected to it) and give much better speeds.

Any ideas/suggestions please?

You need to contact BT ASAP and tell them that you were mis sold Infinity 2 as your line is not capable of even the top speed for Infinity 1 let alone Infinity 2

You're in a banded profile due to an unstable connection. Have you had an engineer out to address the star wiring?

Except that the OP was below 40Mbps before these issues. I am assuming they upgraded to Infinity 2 as the deal made it cheaper than Infinity 1 but presumably knew they weren't going to actually get a speed upgrade.

The problem is not that the line is incapable of Infinity 2 speeds but that it has suddenly taken a nose dive - the actual Infinity version should make no difference to the speeds the OP is getting (in this case).

When the engineer visited, they simply did not connect the wires that went to the extension socket, when installing the Openreach NTE5 socket to replace the old master.

They did not go into the loft at all to look at the "star" wiring.

I knew about the "star" wiring from when we activated BT in 2006, after the previous tenants were using Cable & Wireless (that were taken over by Virgin?) through that other modern socket in our lounge that has nothing to do with BT.

It was the £15 vs £25 that made us upgrade, but I'm pretty miffed we are syncing at 18Mbps now, when we were getting 20-23Mbps before the swapover.

So, are there any other sockets coming off the wiring in the loft that are still live? What you describe suggests there could be extensions fed from the loft that are before the master socket.

If that isn't the case then it is not star wiring.

Only one of three sockets are live now, the lounge one that was master before the NTE5 socket installation.

The extension BT socket in the hall is dead now.

The Cable & Wireless socket has always been dead since we moved in.
