Infinity - Line Stabilisation & Performance

Hi,
Had Infinity installed on 5 days ago (Monday 28th Feb.) and have been getting considerably lower d/load speeds than advised. I was told when they did a check during ordering process I would have no problems in getting 36 to 38Mbps d/load and 7 to 8Mbps upload, the upload speed is as suggested, the d/load speed is another matter.
I'm currently connected via wifi (802.11g) for both PC and PS3 (due to master socket being a fair distance from PC on a different floor) and getting about 4 to 7Mbps d/load, I know that Wifi will cause a bottleneck, but I wouldn't have thought to that level. I have tried a wired connection and got about 20Mbps max.
I spoke with a BT representative lastnight who informed me they won't look at d/load speed until at least 10 days after installation as this is the minimum stabilisation period. I was a little surprised by that, 10 days minimum, really?
I guess my question is; should I see a dramatic improvement in my Infinity performance from next weekend or am I being fobbed off?
Thanks in advance.

Thanks.
Hi there,
Another option which might be worth considering, would be the use of "Homeplugs" - Basically, as long as your whole house is served by the same electricity meter, then you'd just need to plug one of these into a spare socket by the router and another one, in a spare socket by your PC, then just use standard ethernet cables to connect the homeplugs to the router and the PC, respectively.
The diagram on this page illustrates it better than I can explain.
I hope this info helps.
As mentioned above the HomePlugs work amazingly and setup is very easy also and you can get upto 200 mbps might suggest looking at Devolo AV200 Series there rock solid.

Number of infinity lines available in an FTTC cabi...

I'm in a "rural" area with a reasonably high housing density. I would assume interest in moving from circa 200kb to many Mbit/s will be high. A small FTTC cabinet has been installed but not commissioned. Are there only a limited number of infinity lines available in such cabs or can capacity be incread to meet demand? I'd hate to miss out due to demand having been lucky enough to be in an area getting the service......

IMHO I doubt Openreach would rush to install another larger Infinity cab to cope with any overflow... for a while if ever.
So you want to get in first. If you've registered for Infinity don't just wait to be contacted.
Check regularly using your Telephone Number (for most accurate result) in https://www.btwholesale.com/includes/adsl/main.html
Or scroll down a bit to enter your number in the BT Infinity site.
The checker showed my date had been moved to 30th Sept.... I kept checking as my cab was powered up and you could easily hear it's fans running.
Then on 1st July the checker showed Infinity was available.-

BT Infinity - line calibration and possible speed...

Hi,
We recently had BT Infinity installed (14-03-2013) and the speed has dropped significantly from 37 to about 20mb
Up load seems fairly consistent at 8mb
The engineer told us that the line calibration should only take 24hrs so I'm hoping there is an issue and that we can expect better than 20mb
We've been told to expect at least 25mb although it would be nice to get more
Can you advise how long the calibration should take and maybe check to see if everything is OK?
We have had to reset the router a couple of times
Please advise
Thank you

Solved!
Go to Solution.

You should never restart the Modem in the first 10 day period. In the first 10 days it will gather line Information then after it has enough on all levels it will decide where your line performed best at and set it at that speed. It will then continue to monitor the line forever and make adjustments. The reason why it's important that you do not disconnect the modem as the Cabinet (DLM) will not be able to make connection with the modem meaning it is recording this and will compensate by lowering the speed until it has a connection. Also turning it off suddenly can cause error bursts on top of that, so it is vital you give your line the best history that you can give it.
It will always look at previous history it has and make decisions from it. If it has bad history at the start it's very reluctant to actually improve the speed in future because it's seen it's not had good history in the past. So it will slowly rise the line speed from 12Mbps to lets say 28Mbps. It will increase it increments due to your bad line history, if it has good say you maintained connection for 90 days and you suffered from a power cut and this put your speed to 20Mbps. Over the next 5/7 days you will normally see it jump straight up back to that speed. If you have bad history it will put the speed up slower and it can take 2/3 weeks for it to actually increase the speed as well.

New infinity line and major speed issues with almo...

Hi,
Just has infinity installed after moving from my previous FTTC provider. With the previous provider i was getting 16 down / 1-2 up and it worked great.
Had my my new inifnity line put in on thrsday and i am getting 17 down / 0.5 up!!
I work from home and connect to the office via vpn and remote desktop and its almost unusable. Laggy, slow, unrepsonsive and is constantly dropping the connection with a failed to read from socket error and is making it very difficult to work form home effectively.
I have a 4g EE modem also and if i switch to this it is like lightening compared.
I also had absolutely no connection issues with my previous provider and as i posted above had a mich better uplink speed - which is where i think im getting most of my issues.
When i signed up to BT this is what i was sent via email:
We estimate your download speed will be 19.1Mb.
We estimate your upload speed will be 3.9Mb.
Im fine with the download but the uplink is shocking compared to the estimate - and as i had much better before i think something is amiss.
Also when i signed up i was told that if i had any connection issues with the new line i had to notify BT within 7 days and it woudl eb investingated but it seems there are so many roadblocks to creating support tickets etc.. Its like it s been hard to report a fault on purpose.
Where can i create a support ticket or similar to get this looked at?
Thanks

As you use the internet for work purposes did you have business broadband with your previous provider ?

BT Infinity, Line fault, In-a-rush Engineer, Waste...

Hi Bt Community,
Thanks for all your help, many of you have helped me with your posts prior to this. But now I have a little problem of my own.
After finally getting a moving date last month for my new home with my pregnant girlfriend, we jumped onto the BT Infinity wagon (BT Infinity 2 package, 79mps). We had a date of Monday 23rd for installation. Now, this was booked back in May, so we had this sorted a month in advance. I was told it would be a quick, simple process and that my line can easily be switched back on etc.
The 23rd (last Monday) comes around and as planned I booked the day off work, waited for the Engineer (who was on time) and he came in and started playing with the master socket. He plugged in the BTHUb 5 and it started flashing orange, then the "B" symbol was flashing, meaning there was an issue with the broadband connection. After 25 minutes of talking to his boss, he told me there was nothing he could do and to wait till Wednesday for a call. I asked why the line hadn't been checked prior to his visit and he just shrugged. He was more interested in meeting his quota for the day than to chat and help resolve the situation. He left me clueless and off he went.
Alas, I was patient, I had waited longer for Sky to install their bits when I had them, but at least they had good communication throughout and I knew what was happening and when... I'm happy to wait weeks for a service as long as I'm told what is going on...
Now, I got the call on Wednesday as promised. However it was simply this:
"Hi, I'm calling from BT, just to let you know we are looking to book a new engineer, and we will call on Friday to confirm".
So I wait for a call on Wednesday to be told to wait for a call on Friday? Lovely. But sure, I'll wait some more.
Now, it's Friday, and I get a call saying:
"Hi, I'm calling from BT, just to let you know we have an engineer booked for July 7th, 2 weeks, but if you like I can get this fast-tracked".
"Yes, fast-tracked please"
"Please wait 24-48 hours for a call to confirm".
WHAAAAAAAT?! Why didn't you just fast track it in the first place, my girlfriend and I have already been waiting and have had this service planned since the start of May. What a stupid way to do things.
Now I already emailed them on Wednesday, with no response... I don't know if the line is being fixed, if new optics are being installed, if I have a faulty hub, what? Nothing has been told. I'm just asked to wait.
I hope the BT mods can help, as they seem 10x more helpful than the customer service on the phones, email and face to face.
Thanks, and is this kind of thing normal for BT? Delayed, lack of comms and a pretty shaky start to the service? I was going to add BT TV and all the channels too after Infinity was installed but I dread to think what else could go wrong...
Thanks.
Danny.

GeneralPath of 100k lines drawing performance

Hi!
I find that there is a great difference in time between drawing 1 path of 100 000 lines and 100 paths of 1000 lines.
Drawing 100 paths of 1000 lines is much quicker.
It seems to me that there is some `unlinearity` in drawing alghorithm, ex. drawing time is proportional to n^1,5 may be.
But drawing one path with porthions is not good if I use big line width (>3) and not 255 alpha because of overlapping of two path on junctions.
So, why drawing of path of 100 000 lines is so slow and what can I do to accelerate it?
P.s.
1. I also noticed that drawing with stroke width 1 is much quicker than if width is more than 1. But the time difference if I use single path length not more than about 1000 is not so big.
2. I noticed that if I draw a path of 100 000 lines, turning on antialiasing occelerates rendering. It was strange for me. Antialiasing still slow down rendering if I draw 100 path with 1000 lines - I think it is normal.
3. I use GeneralPath constructor with predefined initial path points count to prevent redundant memory allocation. I tested float and double lineTo and moveTo methods and don`t see the difference in time.
Alexander.

I have the latest Wacom drivers for my model - it's the same driver for all Intuos and Cintiq models. Besides, as I said - the performance is perfect in all other software, except Flash. And also as I said - in Flash CS6 the performance is better than CS5.5, but not better than CS3... It is acceptable though, because it's rare that I will draw such fast lines - in my case I can see a clear difference in performance if I draw fast or slow. I have tried to compare results on my older MacBook Pro and I get similar results...

Receivables and Payables Line Item performance

Does anyone get really slow performance when entering Orders/Invoices into AR or AP? I can't find any other comments about it yet we can't be the only ones which such slow performance.
We get very slow performance with each line taking around 6 seconds to load.
We have 3500 Items and 27,000 Business partners which I wouldn't think is high. We have a new Quad Core HP server and use SBO 2007A SP 00 PL49.
Interestingly if we use the AR Invoice + Payment screen the lines load almost immediately.
I have updated SQL Statistics thinking this might help but no luck.
Does anyone have any ideas?
Thank you in advance.

Hi all
I have answered this question myself after many hours of anquish.
We had User Defined Values (UDV) in the line items which was set up by our SAP vendor. It is a query that updates in the UDF the current stock levels per branch.
When I turn this off the perfomance issue goes so I have decided to remove it from all Forms except Sales Orders where it is of the most use.
Sorry to trouble you all.

Infinity line checker - buyer beware

Long way from the exchange? Fed up with that slow connection? Thinking of ordering Infinity? I have just gone through over a month's worth of problems trying to get Infinity connected as promised by BT, and want to share my experiences with other rural users.
My exchange - Calder Valley- was one of the first to be upgraded to fibre. In September I had recently contracted to Talk Talk and to be honest wasn't getting good service, so idly checked BT's website and was astounded to find infinity available. I phoned immediately and asked for confirmation that my rural location would be able to get the upgrade. The line was checked and yes, I was told the line registered 39.1Mb download, 15Mb upload. I signed up on the spot. I was given a date for engineer install, but then heard nothing. When the equipment failed to arrive I phoned and was told my order had been cancelled. This was blamed on an internal error, the order had not been properly placed by the BT operative. I re-ordered. The line was rechecked as part of this process, same stats. This time I got all the confirmations you would expect. Great. The order tracker showed a message to say my engineer appointment was no longer required, but when I phoned I was told this was an error, ignore it. I got a text to reconfirm the engineer appointment. Equipment arrived, but having waited in all day the engineer failed to show. No contact, just failed to show. Before the end of the day I phoned, and was told there was a problem moving the line back from Talk Talk. I would have a phone line, but would have to wait for Infinity. I was contacted a couple of days later and told that Infinity could not be provided after all, that I would have to revert to a standard package. I was told the speeds promised earlier were based on a postcode check.
I have problems with the service I've received from BT on many levels.
Given what I know now, I would defy BT to deliver Infinity to anyone with my postcode. Its a rural location.
At no point in the order process was there any qualification or note of caution from BT that they might not be able to deliver the speeds quoted. When I ordered I was told I was told that would be roughly what I would get, subject to the normal variations for traffic etc. This would indeed form BTs side of the contract. Given my location I pressed this point on more than one occasion.
On the basis of the line check I was mis-sold the infinity product not once but twice. I severed my contract with BT's competitors on the back of very dubious information, which was sold as factual.
The individuals I have spoken to at BT have all been decent people, very sorry for my troubles etc. But try to get anyone technical, or anyone senior who can take responsibility and actually sort things out. Impossible.
I typed my details into the line checker again today. Click on 'I've got a BT line' which I now have once again - speed prediction 512k. Click on 'I'm not with BT', speed prediction with Infinity 40Mb. Buyer beware!

Thanks Hamish, I appreciate that this is not one for forum advice as such. When I first looked at infinity and wondered how BT could claim to deliver 39Mb to my location I found the forum a useful source. I posted to add to that information pool.
Although I doubted that it would be technically possible to deliver Infinity to me I went ahead on the basis of 'What's the worst that can happen?' Well now I know. I am constantly amazed that a behemoth corporation like BT can provide such p**s poor disjointed service and get away with it. They are not alone unfortunately.
I understand that Calder Valley was selected to pilot Infinty rollout into rural areas. Not much cop so far. I hope others have a better experience, good luck to them.

BT Infinity line checker

I have been monitoring the availability of infinity for my line for months.
The Upminster exchange was selectively enabled at the end of December 2011. Although the telephone number checker has never shown that i can get infinity, the postcode checker has.
For a few months the suggested speed was 14.9meg, that then rose to 24.9 meg and stayed there for a few weeks. This weekend the speed indication rose again to 33meg, but today the POSTCODE checker no longer shows my line as supporting a fibre optic service; what is going on, can anyone throw any light on this and some input from BT Staff woould be appreciated.
Thanks.

The big problem you have is the fact that the telephone number checker does NOT say anything about Infinity which leads people to believe it will not be available to your number yet.
The post code checker is not very accurate as a postcode can be served by more than 1 green street cabinet. (PCP)
If you do not have a BT Telephone line rental with BT this could also be another reason why the telephone number checker is not showing the correct info.
Do you know where your old Green street cabinet is, if you do know, does it have a brand spanking shiny New green Cabinet within about 100ft of it. That will indicate that Infinity will be avaiable sometime.

Infinity, line noise, disconnections: incorrect in...

Hi,
I've had ongoing issues with disconnections on Infinity (and prior to that, copper broadband) - we were getting dozens of disconnections a day - and I think I've found the root cause: intermittent extreme line noise, caused by badly oxidised wiring in the XNTE.
I investigated the entire circuit from faceplate to openreach side of circuit and found the problem to be a very worn connection inside our XNTE (our house is a new build from 2010, so of course we have the infamous XNTE box on the outside wall) - the wires literally fell out of the plug when I touched them.
I've rewired, the line noise has gone and my homehub5 VDSL uptime is nearly two days (its not been this stable since May!) and now I have two questions.
1) Due to the extreme disconnection/error rate, DLM has dropped our data rate to 5.8Mbps download with noise margin of 27/33. How long will it take to re-train? Could/should I request a manual reset? We should be 40Mbps (and indeed, the service ran at this speed for a short while after initial install).
2) My main question: I've read that the XNTE is phased out, and new vDSL installs require the XNTE wiring to be gel-crimped (the XNTE becoming just a simple junction) and a new NTE5 + SSFP (service specific face-plate, I guess this is the one with the filter built into it?) installed as the master socket inside the house. Should this have been done when we switched over to Infinity? Would dearly love some moderator input into this second question. If it turns out we still don't have the correct wiring for Infinity this needs to be addressed.
Thanks in advance for any advice and help.
Solved!
Go to Solution.

Hi punchybda,
Welcome to the forum and thanks for posting about the problems with your line and BT Infinity.
It can take several weeks for DLM to increase the profile again as long as the connection is stable and the noise is gone but if you send in your details we should be able to organise an engineer to visit you and make sure the Infinity set up is up to standard and while he is there he can also organise for the profile to be reset.
Please use the 'contact the mods' link in my forum profile to send in your details and we'll be happy to help you with this. You can find the link by clicking on my username.

MODS PLEASE-Infinity - line connected direct to ex...

I have today discovered that my home line is connected direct to the exchange, not via a street cabinet.
The Infinity FAQ's say "Your phone line may be connected directly to the telephone exchange and not to a local street cabinet."
Can anyone please explain why I can't get Infinity, despite being connected directly to the exchange?

As allanm said
Infinity is fibre to the nearest cabinet and copper from there to you but copper can only be upo to a certain length
so if your direct copper connection to exchange is longer then there is the reason
If any post helps tick the star box on the left

Infinity HH3 wireless performance - worse than HH1...

Back in May we signed up for the 6 month free Infinity trial.
Whilst wireless speeds in the room in which the hub is placed are OK (approx 30-35mbps), speeds throughout the rest of the house are much lower.
We have a TV with wireless connection on which we want to watch using iPlayer. We have also tried the Wii and PS3. iPlayer worked fine (on standard resolution - no chance on HD!) when we had the HH1, but with the HH3 we get buffering and interruptions even on low resolution. Speedtest on a tablet next to the TV shows speeds of less than 1 up to about 8, yet even when the higher speeds are shown we still get occational buffering on low res.
The HH3 is in the same room that the HH1 used to be (albeit not identical positions due to cabling restrictions) - and unfortunately this is at the opposite end of the house to the living room and TV.
Is there anything that we can do to improve the wireless reception? I'm thinking of channel settings or something to boost the signal. I can't easily move the HH3 without having a lot of trailing wires, and am not willing to pay out for new devices. I'm fairly technically competent, but am a novice in terms of WiFi.
We have a couple of months left on the free trial. If we can't sort out something, then I think we'll be going back to the old service at a third of the price of Infinity. At least we can then watch iPlayer again.
Thanks.

If you are paying for a fast connection, then to make full use of the speed, you are better using Ethernet cables or powerline adapters.

BT infinity line stats(Huawei HG612)
