Massive drop in fibre-optic broadband speed

Hello,
We had our fibre-optic set up on 31/8/12, everything went swimmingly and we recieved download speeds averaging around 70MBPS for about a week, however, over the last few days I've realised through a series of speed tests that our download speed has taken a massive dip and now hovers around 20MBPS.
One thing I do find strange is that despite the DL speed drop, our upload speed has remained more-or-less constant. Are there any simple explanations/fixes for this?
Thanks for your time.

It looks as if DLM has decided to lower your profile, possibly because of some noise on the line. Try http://speedtester.bt.com/ and choose the ‘ADSL and Fibre diagnostics’ option, and post the profile it gives as a result. It is fairly common for upload speed not to suffer when there are issues. It is not controlled by DLM in quite the same way as download.
One thing to check is your internal wiring. I had an extension that had been wired off a junction box before the master socket, and it cause similar issues. That was standard GPO practice when it was installed 15 years ago. The FTTC installer should have rewired things, but he incorrectly said it wouln't matter. My download speed went right down to 12Mbps and for a time even 3.5Mbps. Upload remained at 17Mbps all that time. I disconnected the extension and everything came ok again after a few weeks ~ DLM is quick to lower your profile but slow to raise it again.
edit ... I've just been reminded reading a thread on Thinkbroadband that having a Sky box wired in can have a similar effect.

Vodafone Sure Signal and SKY Fibre Optic Broadband

Please help, I have had no Mobile Phone signal for over 6 weeks on four mobile phones at home (which we pay over £150 a month for!) including my two teenage daughters phones who are beside themselves!!My Vodafone sure signal box was working fine (for past two years or more)but stopped working when we switched to SKY Fibre optic broadband from regular SKY broadband I have spoken to Vodafone and SKY for many many hours but still no signal. I'm tempted to ditch both SKY and Vodafone and start fresh with BT!!, this would be such a shame as been with both companies for over 15 years now I have no idea what I need to do to fix this, we have tried Port Forwarding but still no signal. Please help, I am in a mobile blackspot and its driving me cand the family mad.

Although not specifically about Sky Fibre, this (although a bit technical) is an interesting read (in particular the post at 21-Oct-14 10:41:23 advising to de-register the SS via the VF website, wait 30 mins then re-register the SS using a different postcode and if no luck contact VF and ask them to reset the SS from their end). For what it's worth, the Three Home Signal Box works fine over Sky Fibre without any port forwarding or any nonsense - just plug and go - worth knowing if you should decide to switch mobile providers!

Why call it "fibre-optic broadband"?

I've always wondered why BT would choose such a misleading term for Infinity.
Why on earth would they call it fibre-optic broadband? This implies that fibre comes to the customer's house, which is of course not true. The misleading effect becomes worse when they refer to the "fibre-optic router" (the Home Hub) - good luck trying to convince the BT engineer who comes to install the service that it is not a "fibre-optic router" but a bog standard Ethernet router. And of course same goes for the Openreach modem - it's a VDSL2 modem, nothing to do with fibre-optics.
Sure, fibres go up to the street cabinet, and they are welcome to mention it. But the way they market it just makes it misleading for the laypeople and for their own engineers too.
Further down the line, how are they going to market FTTH when it arrives? Fibre-optic broadband again? But we already have that
Very weird indeed.
They could just market it for what it is, a VDSL2 service.

It's the ASA's fault for not stopping Virgin calling their horrible network fibre a few years ago.
Actual fibre will probably be called FIBRE POWERED BY LASER BEAMS
Ahh that's a good point.
The ASA is useless.
So if Virgin started with the misleading language, everybody can follow suit and it's fair game!

Fibre optic broadband on 1921 ISR

Hi,
We are looking to upgrade our ADSL broadband line to a fibre optic one soon. We are currently using an ISR 1921 router with an ADSL interface card (HWIC-1ADSL). Can somebody please advise us if this router is capable of handling a fibre optic line and if so the interface card it will need to receive the signal.
Many thanks
Sam

Recent Broadband upgrade to fibre optic by Eircom
Rang Ericom they cannot sort it out and suggested I contact Apple for an update
Update is not possible without internet connection
What do I do ???
Thanks

You sure your mac ethernet port works.
Give them a call. Verify that they only support windows for coniguration of router. Ask them about future support. If they have heard of the ipad. Ask if they plan on supporting a web browser interface. Ask about their sanity. My $5 router supports a web browser interface.
You could get a cheap wifi router with ethernet ports and with a web browser interface. Connect you mac to you el cheap router. Connect your el cheapo router to the eircom router. Note: Apple routers have a propriety interface too and unless you have a new Mac best to avoid.
Could they switch you to a router that supports a web browser interface?
Get a friend with a windows laptop and ask to come over to get things working.
Internet support is standardized. You mac should be able to access the internet through the router.
What is not standardized is how you configure your router.
Unbelievably, eircom_799 referenced by Neville Hillyer only supports windows for configuration.

Cambridge Fibre Optic broadband

Hi all,
I moved to a new development in Cambridge in early 2012 and because the property's new and in the city centre I expected there to be fibre optic supplied by either BT or Virgin Media. Virgin Media told me that the infrascruture's not in place because the developers hadn't informed them so there's no potential for their fibre optic service at this property, ever.
BT have told me that there is no date set to activate fibre optic at this address, however, they have told me the following:
- The green box in the street opposite our building is ready for fibre optic
- Our exchange is ready for fibre optic and 'accepting new orders'
Currently, I'm getting 3.5MB on my line through Sky and my contract ends in a month and I'd really like to switch to a fibre optic package. There's a number of other properties connected to the same box in the street, with more currently being built (around 1,000 flats in total), so it baffles me why in a city centre we can only get slow broadband!!
My postcode is CB2 8DT. Any one have any other way of finding more information?
Cheers

I assume that you are on the Cherry Hinton exchange, if so then that exchange is enabled for fibre orders. You need to enter your telephone number in the following link and see what the results are: https://www.btwholesale.com/includes/adsl/main.html

My download speed in the Mac App store is horribly slow going at 600kb/s when my internet speed is 60Mb/s fibre optic broadband, why? Every other application has expected (fast) download speeds, so i doubt its my ISP or security settings.

As above, I have also tried clearing caches and changing settings in keychain. I can normally download a 5GB file in roughly 30 in any other application howver, in the App store it takes 4 hours. Very frustrating, any suggestions are very welcome.

Note: using enthernet or Wifi makes no difference in speed.

Fibre-Optics ?

Hi,
I recently switched to fibre optics for broadband in the belief that it was fast ! All the hype etc !
However,I do not find any increase in speed and think it all a bit of a con...it often seems slower than our previous connection...the connection to the local box or junction may well be fibre-optic but the connection from there to my house is the same old tired copper wire connection that has been there possibly since the line first went in to the house.
Surely if my connection is to be called fibre optic,then the actual connection into my house ought to be fibre-optic cable.
Does anyone else feel this ?
Thanks,

Hi,
Currently only one exchange in the UK is trialling out FTTP/H (Fibre to the Premises/Home) (click Here for details)
So hopefully in the future, then yes you might be able to get FTTP/H, but unfortunatly it's only availabe to a select area and not available to every at the moment.
The Fibre-Optic Broadband Rollout is being managed and done by Openreach for all communication providers/ISPs.
BT Retail (your communication provider/ISP) has nothing to do with the rollout of fibre broadband.
cheers

Connecting printer to new fibre optic router

Hi. We have recently upgraded to fibre optic broadband and have a new router. Our HP 3055A printer will not now work. We have followed just about every procedure in the manual and on line, still getting nowhere. We cannot find a 'set up wizard' on the printer, getting nowhere fast!! Need clear and simple instructions, preferably from a user of the same printer who knows the menu headings. Thank you.

Keep pressing the same key over and over....

Fibre optic installation question

Hi
I am interested in fibre optic broadband but there may be problems in physically routing a cable into my house, is it possible to have an engineer call to assess the situation before commencing an order for installation?
Thanks for any replies.

Do you have an existing "copper" phone line that enters the property?
As from the estimate you have posted, you can get FTTC fibre broadband which utilises the existing "copper" line from your property to your street cabinet.
If a survey/extra plant equipment or a "copper" line needs to be installed to the property before hand then a site survey may be needed and you should be notified when you order.

Fibre Optic speed VERY slow.

Hey, I got Fibre optic a few days back and got speeds of 37.5mbps straight away. However, since about 9am this morning, the internet has been soooo slow. It's been between 0.75mbps-3mbps all day.
Sometimes pages don't even load at all! I know that sky will be slowing speeds to test my connection, but surely not all day?

I have been a sky customer for the last 8-9 years, spent a lot of my hard earned money on the service and in the last 18 months I can honestly say that it is SHOCKING. Prices have shot up above inflation, the service has dropped and the quality of Sky as a whole is poor. The stuff on the TV is bad and to get access to the "good" stuff (premium channels) cost's a fortune. But i'll get to my point - I upgraded to sky Fibre after debating to switch to BT Infinity2 - I called Sky and like always they managed to throw a load of discounts at me, hoping I would stay with them. Like a dim-wit I am, I stayed with Sky and upgraded to Fibre Unlimited. I was satisfied I would get my money's worth as the broadband unlimited was very good and stable. Paid for 8Mbps and got 8Mbps. Had fibre since April 2013 and the fastest I have had now is about 24Mbps (and this was about 1am when people are sleeping). On a normal day, I get around 10-12Mbps. I called Sky AFTER the 10 day period and they fed me a load of bull crap. They told me this was a known fault and they were in the middle of deploying this fix to resolve slow connections and it would take around 7 days to roll out. After 7 days, no change at all. Not even a little bit They sent me a new router and it didn't even work, Its now sat in some landfill in Yorkshire. I have complained to sky about 5 times now about this since April, I've done every diagnostic they fed me and it hasn't worked. The whole thing is a con. My day job is an IT Technician and I deal with this farce every day, and the problem 9/10 always lies at Sky's end. SKY ARE PAYING FOR AN INFRASTRUCTURE WITH TOO MANY CUSTOMERS TRYING TO USE IT AT THE SAME TIME. IT’S MAXED OUT AND CAN'T HANDLE DEMAND. I have given up with Sky now, they have 14 days to actually resolve the issue, or I’m cancelling my Direct Debit and switching to BT.

Massive drop in line speed...

Hi all,
I suffered a massive drop in Internet connection speed earlier this week which has so far not improved.
Although I have had ADSL since it's near earliest days and being close to my exchange I have never received a great performance but have become more or less satisfied with the 4\4.5mbps I receive from my Total Broadband Option3 package.
I did receive close to that speed prior to the 8mb upgrade a few years back and an upgrade to 20mbps doesn't promise me any better (availability checker for neighbours etc suggests that faster is available but who is to know?).
On Wednesday (9th February) my connection\synch speed dropped to about half it's usual speed and is now in the region of 240kb rather than the near 500kb I usually receive. I would like to comment that I know my line can achieve better than this as I got download speeds of nearer 600kb for a month or so around October last year.
I power-cycled the router and after the diagnostics had completed etc and the line synch process had completed the speed of the line had dropped again slightly.
Not to sound arrogant but I know all the usual troubleshooting having been through it all before on several occasions each time finding out the issue is with the exchange and so having had no means to affect the problem.
The situation is the same this time in that categorically nothing has changed inside my home nor with my equipment and so I am confident that the problem is external to me, especially considering the massive drop in speed.
I did get a response from a BT forum moderator from a post I placed on another site but the advise I got back was generic at best and didn't suggest anything besides mounting a BT iPlate. that advice was no good for two reasons which are that as nothing in my home has changed fitting an iPlate won't make a 2+mbps connection increase (back to what it was) and that I already have an 'ADSL v1.0' labelled master socket that already contains all the tech that the iPlate does. Having replied to their email stating that I already have the afore mentioned v1.0 master socket I haven't had any response.
So... to explain further...
here are some diagnostic stats for the past couple of days taken from my router (Draytek Vigor 2820n) - sorry the font is small bu tI wanted to keep the layout of the text when I completed the post;

The BT Speed Tester web-site reports my line speed as 2mbps when it was previously 4.5mbps and so as to check actual download speed independently I ran a comparison speed test via SpeedTest.Net which reported much the same result (down\up speed relative to what you would expect for a 2mbps line - Link to SpeedTest.Net results: http://www.speedtest.net/result/711802566.png ).
As you can see from the diagnostic data, the SNR is high and so it does seem to suggest that there is fault on the line. prior to the fault, the SNR was around 6db rather than the 15\16db reported now.
I know it has little factual baring on this incident's potential problems but my last broadband speed issue was caused by water having gotten into the top of the telephone pole at the end of my street which was temporarily fixed by a BT engineer but I don't know whether that was ever permanently fixed?
During that occasion I did suffer very slight noise on my telephone line which I must say isn't the case this time but I thought I would request a line test once again in any case. That unfortunately hasn't helped as the online system tells me 'telephone number not found' and so I can't proceed with the test.
Can anyone offer any advice or is any BT person willing to take on the issue and see it to resolution for me please?
Even trying my own diagnostics trying to speed things along by obtaining a line test hasn't been possible.
I do appreciate that there is a support system in place but that has failed me on this occasion and so I have no faith in going throught the telephone support for BT Broadband when I know that nothing I can affect is at fault.
I can of course provide my account details, email address etc. to anyone BT techie that can assist and I am happy to run any further diagnostics that might me appropriate under the circumstances.
Thanks in advance for any advice and\or furtherance anyone can make towards resolving my issue.
Regards,
Dizzy
PS> if my speed increases beyond 4.5mbps I won't be upset!

5 days into the problem and nothing much has improved. My line speed has now sync'ed into the realms of 2.5mbps so I am at least seeing circa 300kb download speeds (but that's still at least 50% less that I had).
At the end of this post are the latest batch of diag results for anyone who wants to check them over. The only details that seem to change are the 'Cur SNR Margin' and as a result he downstream actual\attainable rate(s).
It just simply seems that something has screwed-up the line and now I'm going throught the tedious increase period to get back to where I was. As increases always take longer that decreases it could be some time before things get back to normal (if they are on a slow increase that it!).
The Kitz Site has some good information related to BRAS profile increases\decreases and depending on how small the increases (if any) are coming my way it could take a very long time to get back to 4.5mbps or thereabouts.
At current rates if increases continue it could be at least 15 days (at 1/2 mbps per 5 days) making it some 20 days total to get back to where I was. All because of a fault that lasted a a fraction of a second.
It is worth mentioning that I did have a similar long period to wait for my line sync speed to increase as a result of the water having gotten into the top of the telephone pole some time ago, which I mentioned in an earlier post, but at that time the drop wasn't too big and so a few days saw the previous performance restored.
For the benefit of others that may read this post, I've explained in my email message to Stephanie that, I have checked with neighbours for any changes they may have made electrically, which they say they haven't, and confirmed that my modem is connected directly to the master socket, and that the master socket is an NTE5 socket so I don't need an iPlate.
I also mentioned that I have ferrite RF chokes on the extension lines and the router<->ADSL line (supplied with the router itself) to cut RF interference that may be picked up by the system.
On a related note, it was commented in another thread that RF chokes can cause problems with ADSL comms but that is not true (I've done a heap of research on the subject). That being said, they can actually have no effect at all if not installed correctly which is why the snap-on-cable type is best because you simply can't get it wrong.
Anyhow, here are the stats and I hope things continue to improve, even if it does take 20 days!

Broadband speed dropped from 10Mb to 250K overnigh...

My broadband speeds have dropped massively overnight and I was wondering if any of the experts on here can give me some guidance on what to try or to do next?
I've been on BT Total Broadband for ages and it was running typically at about 10Mbps according to occasional checks on Speedtest.net since early May when my line was upgraded - previous had been at about 6Mb. However, today I noticed my internet access was sluggish, I tried Speedtest.net again and was shocked to find I was being quoted a download speed of 0.24Mb (upload strangely was higher at 0.38). I then tried Speedtester.bt.com and it says my IP profile is 250Kbps with an actual speed of 159Kbps, so this makes it sound like I'm being throttled down, yet I haven't even come close to any limits. Also it's a bit strange to have it happen so suddenly - everything was working fine last night and the router has been on 24/7 (although I did reset it this morning thinking that maybe this would solve the speed issue - no such luck!)
I'll post the stats from the Speedtest and from my router below (I use a Belkin, not the Homehub in case that makes a difference), but would appreciate some ideas about what might have happened and anything I can do.

Hi there I'm also having the same problem unfortunately. A coupe of days ago I was transferring a file from my laptop to my desktop via wireless and it caused my home hub 2 to hang. I had to reboot it a couple of times to get it working again but once it was back up again I found browsing to be really slow. I went on speedtest.net and discovered that I was getting 250k down and about 300k up. I power cycled the home hub a few times and checked all of my microfilters and connections (just to be on the safe side) but it was still slow. I went on the btspeedtest site and it is showing that my ip profile is 250k even though I am connected at 4,500k. I called the bt helpdesk this evening and was told that there looks like there was a problem but that they are showing my ip profile as being 3000k now and that I should check in a few hours on the bt speedtest site again. Well I did and it's still showing as 250k. The details from my hub and the speedtest site are below. Any thoughts and help would be very greatly appreciated.

Broadband Speed dropped and wont come back

Hi, I need help and advice please.
Background info first though, so please bare with me.
During last July 2011 I was fed up of very low speeds and managed to get a BT engineer out to check the wiring etc... He did a great job by finding a badly insulated cable between myself and the Cabinet in our village. He also changed our master socket to a newer version.
Over the next few days my broadband speed went from 0.74mb download to 1.95mb download. Fantastic!
This speed has pretty much been a consistent rarely dropping below 1.7mb and at times has even gone up to my highest recorded of 2.46mb. I thought this was brilliant, I could watch iPlayer no problems and xbox live was even bearable (most of the time).
The big problem where I live is sometimes we have power cuts. Sometimes lasting hours but mainly just for seconds. Even so it switches the BB router off. (I know, but not my fault)
When we had the freak snow fall the other month problems started to raise their head. The computers in the household found issues connecting to the router and to resolve this BT BB Helpdesk kept advising me to reset router to enable connection. After connecting new ADSL filters the speed returned but connection issues continued.
BT supplied me with a brand new home hub 3 which I connected thinking it would give me my 2.4mb speeds again. Oh No. To be fare I think I was getting 1.95mb but I wanted more, as most people would. Why cant I get 2.4mb most of the time I have had for a few months.
Anyway I contacted BT who were kind enough to send a BT engineer out. He Said to me the Broadband speed is put out at the exchange (4.5km) at 8mb and comes into our village at between 3mb and 4mb. He detected no fault on the lines and spent the next 3 hours renewing 'D' and 'E' I think side of cabling (found this out later). He mentioned the noise was high but did something to lower it. On leaving he said I had 2.5mb and was confidant it would rise to 3mb.
Great not drastic but should give me 250kbs to 50kbs extra.
The day he was at my house we had 2 short power cuts followed by another couple some days later. This has not helped I'm sure.
NOW TO THE ISSUE.
My download speed since that day has not gone above 1.46mb download and every time I speak to the call centre they tell me my line is only capable of 2mb therefore 1.46mb is within acceptable range.
I am so tired of explaining that I was capable of receiving 2.4mb some 2 months ago yet now since the new hub 3 and line fiddling I am only capable of a 2mb downstream - 1.46mb DLS.
I know I have to wait 3 - 10 days but with power cuts its a nightmare, and they are so adamant about my 2mb downstream limit What the hell has happened.
Here is a link to my recorded (Speedtest.net) data over the past 11 months showing actual proof of receiving 2.46mb:

Solved!

Hi JONNYYOUNG,
I'm not educated enough to help but it mat reassure you, as it did me, to know your circumstances are not unique.
Your story sounds very simialr to my experiende last November, speeds and line length being very similar. An engineer said there was noise on my line so he switched me to another pair. Did the engineer do that for you too ? Net result my speed dropped from ~2.3 to ~1.4Mbps.
Fortunately a 21CN upgrade at my excahnge has brought my speed back up to ~2.4Mbps.
I'm sure imjolly, john46 and maybe a mod if you need it will sort you out as well as they did me.
Good luck,
dfenceman
Best regards,

Recent drop in broadband speed

Hi,
I've been with BT approx 2 months now (since I moved into my new house) and have usually got a speed of ~2Mbps.
However over the past few days I've noticed an obvious drop in speed.
I've run the BT Speed Test and here are my results:
Download speed achieved during the test was - 674 Kbps

Is anyone able to offer any advice on what the problem may be?
I'm on BT Unlimited Broadband (up to 20Mb) and the speed is so bad that I can barely use BBC Iplayer without buffering for ages.
Thanks

Hi Welcome to the forums
youe speed has dropped because of disconnections of your hub causing a drop in your ip profile if you do the following then we can help you further
If you post the full stats from your router
For homehub – type 192.168.1.254 into your browser
Navigate to ADSL Settings or use the A-Z at the top right of the home page and scroll down to ADSL Settings and click on it
Click on More Details and then post the full results.
also post the full results from http://speedtester.bt.com/
Have you tried connecting to the test socket at the rear of the master socket
Have you tried the quiet line test? - dial 17070 option 2 - should hear nothing - best done with a corded phone. if cordless phone you may hear a 'dull hum' which is normal
also you could try the hints given by poster RogerB in this link they may help http://community.bt.com/t5/BB-in-Home/Poor-Broadband-speed/m-p/14217#M8397
