Possibly somehow your IP profile dropped for a bit and the PN copy updated, downwards. Did you do another reconnection, raising the IP Profile and he PN one not yet updated? (Remember, it isn't done in real-time). Certainly you need to check the PN Current line speed.

I can't remember if you have access to the line stats, either through a hacked modem or a non-PN router?

Try http://www.thinkbroadband.com/speedtest.html you get a copy of the graph during the test afterwards.

Spikes in flash testers are not uncommon and depending on how the specific ookla server is set up it can report a reading higher than you would expect

I don't have a hacked modem. I have got an old VDSL modem/router combo from Vtesse Networks' consumer broadband venture but not familiar with it.

The PN line stats now are:
Telephone number:
01788XXXXXX
Phone exchange:
RUGBY
Estimated line speed:
54Mb (Download speed could vary depending on line conditions. Estimates are the maximum speeds that your phone line can support. These speeds are dependent on the package you choose.) - Checked on 2014-01-23 16:45:58
Current line speed:
47.8 Mb

Meaning it has over time dropped from 78 mbps to 53 mbps to 47.8 mbps.

Will do, as soon as I can have all the bandwidth to myself!

(Geeky family problems haha)

Those aren't line stats . Connection/sync speed, attenuation and noise margins are the minimum you get with line stats.

The Current line speed though is 47.8Mbps. That strongly implies to me my suggestion was correct.

Tomorrow, in daylight, turn off the modem for 5 minutes. Then back on. Check the new BT IP Profile, then the Plusnet line speed. The PN line speed is unlikely to self-correct for a few hours, but if you ring support they can reset it there and then.

Ah yes, my bad.

Will give it a go. But 47.8 mbps is still unacceptable when 1) I was at 53 on day of install*, and 2) I should be on far more than even 53 when I get the bridge tap fixed.

[*Crosstalk can be ignored as a cause for slowdown as the cab is absolutely full so no new connections since mine.]

Maybe I'm being greedy, but we download on average 27GB a day. Every meg counts

Edited to add - I think I'd rather poke myself in the eye with a toothpick than stay on hold with Plusnet ever again...

Right, now the Plusnet "current line speed" has increased to 53 mbps but my connection is still at 44.

Hopefully modem reboot will fix this.

UPDATE:

Woo! Reboot worked! Back to 50 mbps...

And further good news! Plusnet just called - they're sending an SFI engineer tomorrow to see what's causing the slowdown (hopefully it's just the bridge tap).

On the support ticket there are some interesting stats. Still not proper line stats I don't think, but here's a screenshot anyway...

Beware of SFI will charge you lot of money!
