Confirmed using 1GB link. Interestingly the speed doesn't vary very much at all using wired or wireless (I'm a few feet away from the router) I may have to downgrade to a 200mb circuit according to BT.

As the line was only installed yesterday perhps give it a few days to 'settle down'/improve to see if that makes a difference before (rightfully) kicking up a fuss?

I recall reading on a blog somewhere that someone else who had an FTTP line found it took a few days for them to achieve their promised speeds

I don't believe the '10 day training' period/theory that goes with FTTC/ADSL but I wonder if with FTTP lines it takes BT's systems a few days to fully register the line as active/the right profile.. and as such I am suggesting giving it 3/4 days to see if that makes a difference.

Possibly. I've just spoken to BT again and told them I'm not happy with the suggestion of downgrading to a 200mbps circuit. They have suggested waiting 72 hours to see if the line speed improves before they will investigate. I'll keep you informed. Thanks all for your suggestions.

Andrews and Arnold. Enough said.

That won't help the OP or any Openreach Johnny sent to visit though.

Nah, I've fitted enough of 'em to know that it should just rock and roll from the get go.

Indeed not. If it is that it's probably going to be painful.

If after the initial round of 'visits' the original poster has got nowhere, i.e. no-one in power picked up the possible issue then they need to email me [email protected] and will try to pester the right people.

Can you tell us the exchange name.

If the (Host) exchange is small, or newly enabled with Fibre it is mostly the suggested SVLAN issue. There can also be more than 1 SVLAN on the exchange so you may have been put in the newest ( smallest) one.

I think there are some semi automated routines for increasing SVLAN sizes up to the full 1Gb (could be 10Gb) transmission block. So these could kick in to increase the bandwidth as you will have broken the threshold simply by doing the speedtests ( If it was broken for a long enough period, not just seconds!).

It is likely that this has cleared other cases that were similar.

I believe ISPs can see the SVLAN sizes but unlikely that the 1st line support either know about this or how to look.

This would also apply to an ISP using BT wholesale products.

Some operators will have their own backhaul and the first 330Mb customer they have could also hit a similar pinch point.

Thank you. I'll keep you posted with a due amount of dread and trepidation.

Hi sure it's LCBRI (Brinscall)

Meaning:

- we don't know what is wrong;
- we aren't going to bother trying to find out;
- we don't care;
- tough.

Is that first-line support or have you got through to someone who has a clue?

Sadly it's the same old story with BT Retail...unless you can speak to the right person you're pretty screwed. I've only spoken to 1st line (UK based) but I've put my foot down and said I'll wait the 72 period they've requested but I want this escalating internally with BT Retail. As many have said sadly this will likely involve throwing the call at Openreach. Which I'm sure will involve an Openreach engineer scratching his head, attempting a speed test with similar results...I can only assume it will then hopefully be passed to someone with more knowledge to look at the SVLANs.
