Disappointed with Infinity 2 Speed on Install Date


[link to this post]
 
Hi,

I have just had BT Infinity 2 installed today. The BT Wholesale Checker shows the following for my number:

FTTC Range A (Clean) 59.3 43.7 16.2 10 -- Available
FTTC Range B (Impacted) 49.7 26.7 16.2 7.4 -- Available

But a wired speedtest.net result comes back with: just 22Mbps http://www.speedtest.net/my-result/3287469432

I have gone into the Hub 5 connection status which shows:

VDSL Line Status

Connection Information

Line state: Connected
Connection time: 0 days, 04:43:37
Downstream: 23.38 Mbps
Upstream: 5.45 Mbps

What can I do? as a 20Mb line is not much more impressive than the 7Mb i was getting on my traditional ADSL line.

Thanks

Self install or engineer install?

i.e. do you have a VDSL faceplate i.e. http://www.coolwebhome.co.uk/faceplate

So they gave you a faceplate? And when you get down to the test socket (example in http://www.coolwebhome.co.uk/faceplate ) none of the other phone sockets in the property work?

Do you know how far you are from the cabinet?

Your speeds suggest around 1km, but the checker suggests around 300m, The checker is sometimes wrong, so it is worth trying to figure out.

Hi,

The engineer installed a new faceplate with the letters MK2 on it. This is the only telephone line in the house, we don't have other extensions.

Thanks

Can you also post the noise margin reported by the HH5, please?

The attenuation is quite high and the noise margin isn't much above the target. I would guess it's not going to get much better.

So why does the offical BT openreach checker show that I will get 59.3 - I can understand that these are sometimes a little out; but getting just over 20 when the checker shows almost 60 is quite a large gap.

If you look at Range B you appear to have an impacted line.

Hi,

I did a quick google for impacted line; which brings up the following TB article, which talks about internal wiring as the issue, is this the only case for an impacted line?

I never thought an impacted line would be due to internal wiring. How would BTWholesale know about that?

No Idea; it's just what the TB article says:

What do these changes mean and what is an impacted line? The clue is in the checker text which refers to a bridge tap and wiring issues. In laymans terms an impacted line is one where the VDSL2 service is running slower due to the presence of telephone extension wiring, or other things like non-twisted pair wiring in a home, or bad practice wiring (e.g. not using a coloured pair, but a wire from two different pairs). For the first four years of the FTTC roll-out these issues have largely been avoided, since the engineers arrive and install a filter faceplate and install a dedicated data extension if it was ordered. Once self-install becomes common we expect to see the same wiring issues cropping up that have regularly seen people with ADSL and ADSL2+ getting lower speeds than they should.

Because line testing can detect and report the effect of things like star wiring or bridge taps.

Bridge tap is like a T junction in the wiring, e.g. on an old house you might have a junction on the outside of the house and bits of cable running from it

Have you figured out how far you are from the cabinet?

Note that article (correctly) points out that an engineer install with the VDSL2 interstitial filter plate should normally avoid that issue.

Is the wiring at all odd in your house? In particular, is the master socket definitely the first "end point" of the incoming line, or is there a junction box somewhere feeding one or more extensions before it?

Hi,

The Master socket is in the living room; and i can follow the cable from the pole directly to the socket into the living room.

I had the socket installed about 6 years ago when i first moved into the property.

I am still trying to work out where the cab is that i am fed from.

Thanks

So what is to be gained by having a self install? You might save a few bob but forever have a lousy speed. Of course it might not be all coming up roses if a contractor does your installation.

Saves a day off work to wait in for the engineer.

The lousy speed should be fixable, and providers hopefully include a little note about microfilters and buying a VDSL2 faceplate if they want the best performance.

Sure a home install might be OK for some and maybe such customers have the technical ability to upgrade the master socket and resolve internal wiring problems. Just as long there is the ability to ask for a engineer visit and pay a supplement for his services, then fine. The replacement/upgraded master socket comes free as well.

As the "baby sitter" for other family members having FTTC installs, on every occasion there has been a benefit in having an engineer install, usually to get the master socket moved to be next to the desktop computer and in one case to replace the drop wire. Remember that not everyone knows what a screwdriver is or for that matter, how to use it!
