Ok another update.

Had another engineer come round this morning. Really friendly guy. Anyway he replaced an old aluminium cable outside down the road to copper, which means it's copper all the way to the local cab. On his tester he was getting around 31Mb on the aluminium before he replaced it to copper. So my connection was losing more than 5megs. He also did some work on the pole. Now I'm seeing some improvement. My IP profile has raised to 28974 and on the the JDSU it was syncing at 30Mb. He said to give it 48 hours and see if it raises and if I'm still not happy with that then to call them round again and they may replace the drop wire, however he said that was looking fine.

So all in all, I'm happy with the increase but I was hoping to get slightly above 30. I'll see if it increases over the next couple of days.

But yeah, basically I knew something dodgy was up when I wasn't getting anything more than 17-18Mb despite not being that far from the cab and the checker quoting me higher etc.

So will the profile hopefully increase if I just leave everything or would it have shown on the engineers JDSU if it was capable of more?

my infinity sometimes behaves strangly,for instance sometimes I will get max ip profile then it dropped down to 25k after a few months and I stayed connected for 20 days with no raise so I gave the hh and modem a restart and it sprang up to 35k.other times after drops it will raise itself after 3-5 days but what I have noticed though is it's best to leave the modem alone,if no change after 10 days maybe try a restart.

So, does this mean that potentially I'm stuck with 20Mb? Will the profile increase?

What do you mean by "stuck with"? You make it sound like a *bad* thing. You're getting more than 10 times the speed of the average UK broadband user and enough bandwidth to stream 4 HD channels simultaneously! Some people are so ungrateful I can only get 1.5Mb - and that's on a good day. I'd kill for 10Mb, let alone 20Mb

You've had the world's most helpful BT engineer I've ever heard of! BT won't move me to a new port, despite the port at the exchange haven been proven faulty (injecting noise and ADSL tones onto the even when my equipment is disconnected) and my broadband has been barely working for the last 6 months. 15 phone calls, 35 emails and two new engineer visits and they still refuse to even *try* me on a new port. Shame there's such a variation in the helpfulness of BT engineers.

That call is not down to the Openreach engineers but the owning Communications Providers, e.g. BT wholesale. The engineer will report back their findings and its upto the CP to descide what to do , if anything. The Openreach engineer is acting as an agent for the CP.

Are you saying there is noise on the phone line with a corded phone into the test socket inside the master?

If so, have you been reporting voice faults to your phone provider, or broadband faults to your ISP?

Yes. But I can only hear the ADSL tones on the line if my router has also been plugged in within the last 10 seconds. The tones disappear a few seconds after I unplug my router from the ADSL socket (the noise I'm hearing is apparently the remote DSL equipment trying to talk to my router). Basically the microfilter on the port at the exchange is faulty.

Tricky.

One thing that is certain is that FTTC or LLU would cure that though. I assume you can't get either.

(doh! - forgot to login, but the anon reply to your post a few seconds ago is mine)

But because it only happens when ASDL is in operation, the voice fault team won't look at it and say it's a broadband fault. To make everything *much* worse, the whole problem is intermittent and wasn't happening when the engineer visited. But basically it can make my connection unusable, with broadband resyncing several times an hour and additionally, whenever anyone rings me or if I take the phone off the hook.

Just had a new phoneline and BT Infinity installed a few hours ago. My distance from the cab is 547m and my IP profile is 38717 kbps down and 10000 kbps up.

A few quick speedtests show my throughput as 37.5 down and 7.5 up, which is pretty good for my IP profiles.

Looking good in my books. I still have Sky LLU on my existing line, which happily chugs along at 6.5mbit down and just under 1mbit up.
