Will post a pic later, as FF is locking and IE posting the same errors I posted yesterday morning at this time. Actual download for the last few tests have been in line with the line profile. The biggest problem is that my profile has been lowered to 11.08Mbps for no apparent reason. I am not sure if ADSL2+ can still suffer a stuck profile, or if I may have developed a line fault, though it was strange another user reported strange results.
The very latest flash has caused problems with W8 Firefox. I have also experienced the old windows false 'No Internet Access' icon on the toolbar. Had a W8 update in the last couple of days which may well explain things network-wise.
Edit 10.10am You will see in the pic I posted above the better upload speed with the Vigor 120 modem and Apple Airport Extreme over the Fritzbox and Billion.

In reply to a post by professor973:

I haven't seen any reports at all of it doing so, other than on FTTC where a modem resync may complete without a PPP session drop, meaning no sync update is sent from OR to BTW.

... though it was strange another user reported strange results.

If you mean b4dger earlier on, he was reporting low throughput speeds - the opposite of what you posted. That could have been a normal hiccup somewhere.

Just like yesterday BT Speedtester back up again. You can now see my sickly profile that used to be 15 - 16Mbps with 14Mbps download. Looks like I need to dig out the corded phone and go on a noise-sniffing expedition!

Edit: 11.57am Quiet-line Test with corded phone as quiet as a graveyard, so may be time to raise a ticket.

Two different things though.

There is nothing wrong about those speeds in relation to the IP Profiles. (And I see the upstream is reported, contrary to what I thought). I assume you have checked the downstream IP Profile is consistent with your sync? If the sync has dropped a lot, we need to see the full router stats.

What was worrying me earlier was:-

... with both my BT profiles showing a lot lower than the speeds I am actually getting.

Was there a typo, or a word or so missing there? It seeems to have been a red herring, which I have been trying to catch with a rod and line, not a net.

Well I have pointed it toward Freeola and though 13 minutes is a little slower than their usual detailed personalised response, I doubt many ISP's will better it!

As there was no audible noise on my line I decided to sort it by switching back to my Billion 7800N router. This allowed me to run Routerstats lite and actually see my sync and snr.. Routerstats pointed out a couple of local noise spikes this afternoon which could have reduced my profile. Fortunately, the Billion allowed me to pull the snr back down to 6 which instantly gave me another 2Mbps download. Though this connection would happily run at a evening snr of just 1, I will leave it meandering between 5 and 6 for now to allow for it to settle. Time to Ebay the Fritzbox and Airport Extreme methinks!
