BT Infinity & FTTx Discussion

R0Z4G · 2 Mar 2014 at 22:45

my max download speed was 60mb and now its dropped to 30mb and I have to reboot the router to get full speed again? any ideas? HH5 on infinite 80 package

AWPC · 3 Mar 2014 at 09:36

Had 3 months of stable 80 up 20 down (could even download @ 100 though) last few days its dropped to 60/17 & everything is sluggish now rebooted the HH5 it makes no difference.

Only 2km from the main exchange as well

Finally! after years of oppression!!

I TASTE HIGH SPEED INTERNET for the first time!

I only just had the engineer round and i instantly picked something to download.

This will go higher as I hit 17mbps at one point.

So happy!

Origin is about as accurate as Stevie Wonder in darts match. I've seen Origin report download speeds physically impossible for lines.

Try - http://speedtest.btwholesale.com/

Allnamestaken · 4 Mar 2014 at 14:18

No but the file actually did download at that speed, ive used speed test and at the moment im hitting about 78mb.

The cab is right outside my door in my new apartment.

I was on 2mb in my old house

.

In the last 20 minutes ive installed - BFBC 2 - BF2142 - CS source - lol.

So happy to be back in the modern age again.

According to the screen grab there's 5.38GB remaining and it's estimating that it'll take 586 seconds to complete. A quick calculation appears to give 73.4Mbps, not the 89.8Mbps the dialog states.

If it's a FTTC connection then the lower figure is much more credible, especially given your other speed test results.

Allnamestaken · 4 Mar 2014 at 14:46

Whats with all the doubt? all I said is it hit 17mbps once maybe but its stablized around 11/12.

Im just happy getting off this stone age piece of **** internet that ive suffered for way to long.

Impossible. Origin isn't accurate.

U are not getting 78Mb from FTTC - no way. Because 79999k x 9679% = 77.43Mbps

BT limit IP Profile rate of 77.43Mbps and after overhead and real term of throughput is no more than 75Mbps. (BT, Zen are 75Mbps throughput. Plusnet & few other isp's are 72/73Mbps throughput)

So, you are more likely getting around between 72 to 75Mbps.

IME BT FTTx starts off great I was getting up to 100Mb even though they capped it to 80Mb in the last 2 weeks its fallen apart I am now getting 58-60Mb tops & getting BT to help is too much hassle they are utterly hopeless

Took the dog for a walk yesterday and there was a gent spraying the floor next to my nearest cabinet marking out where the fibre cab is going. Can't frigging wait now! Give me speed!

Armadillo · 5 Mar 2014 at 18:39

Mine is going to be installed this coming monday (hopefully). I've just noticed something though, will this cause a problem or will the engineer take care of it?

I have one of these http://www.telephonesuk.co.uk/images/large/52a.jpg

Then the socket is connected to that. I assumed they would just replace that box with a modern socket, but there is minimal phone line coming into it. It's basically mounted right where the phone line comes in to the house. There is small run of phone line to it, but no idea how much line the modern sockets need.

I get 9.25MByte/s sustained throughput when hitting max speeds on 80/20 FTTC though generally only see half that on Origin :S Steam, etc. will give me full speeds 24x7.

Origin doesn't seem very accurate at all - seen it reporting 3MB/s when according to the router its only doing 1.8MB/s :S

Buyer beware on BT Infinity 2 crosstalk is causing DLM to kick in it might take a few months but once it kicks in its almost impossible to get your IP profile raised again.

Look on the official BT forums its the no1 issue right now with no end in sight :eek:

Crosstalk due to the poor copper cable the other side of the fibre?

I could be wrong but my understanding is the crosstalk is caused by increased congestion at the exchange & BT not yet having an automated system to deal with this so as your exchange or cabinet gets near capacity crosstalk means DLM kicks in & lowers your IP profile (which BT mods on their official forums tell me is very difficult to get BT Wholesale to raise it again so your effectively stuck with what you get as long as its 50-60% within your original bandwidth quote that's it :rolleyes:

).

Obviously what they do not tell you that in the small print :eek:

bulldog147 · 7 Mar 2014 at 21:43

My fibre isn't affect by crosstalk or DLM kicked in yet!

No.

The second effect, crosstalk, describes the leakage of the signal in a copper pair into neighbouring pairs. “All my neighbours get a little bit of the signal sent on my pair, and vice versa: the signal I receive is not only the useful signal transmitted on my pair but also noise, the contributed components from all my active VDSL2 neighbours,” says Paul Spruyt, xDSL technology strategist at Alcatel-Lucent.

Typical a cable bundle comprises several tens to several hundred copper pairs. The signal-to-noise ratio on each pair dictates the overall achievable data rate to the user and on short loops it is the crosstalk that is the main noise culprit.

well seems things are slowly moving along on my exchange. a few new fttc cabinets have now been installed and iv even gained a speed bust to my up to 8 meg connection. and the works not been finished as far as i can tell.

its down to be up and running sometime in june, cant wait i may finally break the 5 meg barrier!!!
