Poor speed and fluctuation performance

Hi just got infinity 2 installed on 02/09/14 and experiancing poor speeds. getting on average 20Mb Dl and 12UL. I am 100meters from the exchange box, with new wiring to house and throughout. my profile is (see below) tried restarting router disconnecting everything etc but to no avail, is it possible that my profile needs to be reset. Any help would be greatly recieved. My neighbour is getting 78Mb Dl
Thanks

BT Infinity 2 Speed Issues

Got BT Infinity 2 installed on November 14th 2013 & since then I've had two periods where the speed appears to drop to that of Infinity 1 speeds, but the upload generally remains in the region of Infinity 2 speeds.

It is possible that any problem you are currently, or had previously experienced may have been caused by traffic congestion on the Internet or by the server you were accessing responding slowly.
If you continue to encounter a problem with a specific server, please contact the administrator of that server in the first instance.
Here are my speed test results via http://www.speedtest.net/
35.44Mbps Download & 18.63Mbps Upload with a ping of 27ms
Have already phoned BT about the issue the first time, when they told me to reset the modem, this was despite the service not having been active for 10 days & I was under the impression that you are supposed to leave it to acheive best speed. I have saw the connection wirelessly get about 63Mbps down & 18/19Mbps up for several days at a time.
The problem seems to be, its running at a speed where browsing is generally always fast enough. I am only catching that the connection speed is essentially half of what it should be when I run speed checks via several speed checking websites including BT's own.
I have read the problem of Christmas lights, & at least in my home for now, I can eliminate that as the cause. I don't have any Christmas decorations/lights up just now. Just wondering if there is anything that could explain why I am getting such low download speeds, but the upload remains on Infinity 2 levels, when previously I know the connection can run a lot lot faster.
Any help advice would of course be greatly appreciated.

Just restarted my Home Hub 5 & this is the result from the internal Hub manager.

Not quite the dizzy heights of 70Mbps I've seen before, a little improvement which I've also saw before upon a restart/reset. Just wondering what the issue is with the speed dropping. When I have BT Broadband with the Home Hub 3, I never had any issues with speed, it connected & was rock solid. Already regretting upgrading to BT Infinity 2 as when you don't seem to check the speed you are getting, it seems to drop. Only noticable when you actually run a speed check to see if you are actually getting what you are paying for.
Surely I shouldn't need to keep resetting/restarting my Home Hub 5? I know its bad for the connection & to be honest I think its an issue with BT's new installation of FTTC cabinets in my area. The engineer changed my telephone socket face plate over, so its a filtered socket at the main line. No other phones in the house have filters on them as they are no longer needed, so I'm just looking for answers as to why I'm seemingly not getting anywhere near the speed I am paying for (I know with the internet speeds can vary, but its been twice now in about a month I've caught this connection running at just over 30Mbps, when its happily ran before at nearer 70Mbps).
Hopefully the further tests/results can shed some light on this for someone more knowledgable.
Thanks again for the replies so far & of course for any further help/advice with regards this issue.

Very slow infinity 2 speeds and regular drops in c...

since i had my infinity 2 connection set up on the 4th april 2014 i have experience multiple and regular drops in connection. happening every day or so.
i have also been getting much lower speeds than i should be getting. i was advertised 65mb down and 15mb up! i am currently getting 33mbps down and 6mbps up. this is round about the speed i have always got but it seems to be going down slowly (i was getting 37mbps straight after installation).
i have tried contacting bt multiple times and nothing has been done. i believe i need an engineer out to test the line in my street as there seems to be serious problems with my connectivity and i know it is not something to do with my internal wiring. i am using ethernet connection from my homehub 5 to my computer.
something needs to be done asap as i have been playing for infinity 2 speeds and i am currently getting speeds lower than infinity 1 speeds and with continual drops in connection. THIS IS NOT ACCEPTABLE :s

How to improve spreadsheet speed when single-threaded VBA is the bottleneck.

My brother works with massive Excel spreadsheets and needs to speed them up. Gigabytes in size and often with a million rows and many sheets within the workbook. He's already refined the sheets to take advantage of Excel's multi-thread recalculation and
seen significant improvements, but he's hit a stumbling block. He uses extensive VBA code to aid clarity, but the VB engine is single-threaded, and these relatively simple functions can be called millions of times. Some functions are trivial (e.g. conversion
functions) and just for clarity and easily unwound (at the expense of clarity), some could be unwound but that would make the spreadsheets much more complex, and others could not be unwound.
He's aware of http://www.analystcave.com/excel-vba-multithreading-tool/ and similar tools but they don't help as the granularity is insufficiently fine.
So what can he do? A search shows requests for multi-threaded VBA going back over a decade.
qts

Hi,
>> The VB engine is single-threaded, and these relatively simple functions can be called millions of times.
The Office Object Model is
Single-Threaded Apartments, if the performance bottleneck is the Excel Object Model operation, the multiple-thread will not improve the performance significantly.
>> How to improve spreadsheet speed when single-threaded VBA is the bottleneck.
The performance optimization should be based on the business. Since I’m not familiar with your business, so I can only give you some general suggestions from the technical perspective. According to your description, the size of the spreadsheet had reached
Gigabytes and data volume is about 1 million rows. If so, I will suggest you storing the data to SQL Server and then use the analysis tools (e.g. Power Pivot).
Create a memory-efficient Data Model using Excel 2013
and the Power Pivot add-in
As
ryguy72 suggested, you can also leverage some other third party data processing tool
according to your business requirement.

ADSL to Infinity, poor sync speeds

Hi all
We've just switched from an ADSL connection to Infinity 1.
Our ADSL connection was mediocre as we were pretty far from the exchange. Stats were something like:
Attenuation: ~50dB
Downstream: ~3800kbps
Upstream: ~1100kbps
We had Infinity installed yesterday. Stats are as follows (from HH5):
Line attenuation: 0.0 / 29.2
Signal attenuation: 0.0 / 22.8
Data rate: 1156 / 6558
Maximum data rate: 1164 / 6477
Noise margin: 6.5 / 6.1
I'm pretty disappointed with this. I wasn't expecting miracles, but given the significant decrease in attenuation I was hoping for a bigger increase in downstream than from 3.8Mb to 6.5Mb, and certainly wasn't expecting upload speed to stay about the same!
Our downstream prediction prior to install was about 20Mbps. Plugging my attenuation into a VDSL2 calculator site gives ~16Mbps (using the line attenuation) or ~21Mbps (using the signal attenuation).
Surely there is something amiss here? Should I wait for BT's DLM process to complete or is the problem likely to be within my house?

The DSL checker is working now:
FTTC Range A (Clean)
Downstream: High 29.2, Low 20.3
Upstream: High 6.5, Low 4.6
FTTC Range B (Impacted)
Downstream: High 23.3, Low 11.4
Upstream: High 5.7, Low 2.5
Current HH5 stats are:
Data rate: 797 / 6881
Maximum data rate: 1201 / 6939
Noise margin: 18.3 / 6.2
Line attenuation: 0.0 / 28.8
Signal attenuation: 0.0 / 22.5
The line resynced yesterday morning and dropped the upload from 1164 to 797. No idea why I now have this massive upload noise margin as the line has been perfectly stable.
Clearly something is wrong as I'm getting 6.8 downstream compared to the most pessimistic estimate of 11.4 for an "impacted" line, and 0.8 upstream compared to 2.5.

Hi Arsie,
Your IP profile is very low, which is the reason for the slow speeds as Im sure you've guessed. Have you been restarrting, unplugging or resetting your hub in an effort to get the IP profile to increase? The IP profile will rise when 3-5 days of a solid connection has been achieved, any disconnections will restart this time scale.
Has your hub been disconnecting at all? And once did it disconnect so low to give you that profile? Unfortunately it takes only 75 minutes for the profile to drop

BT Infinity 2 Installed today - Very Poor Speeds

Hi,
I have just had BT Infinity 2 installed today to an Openreach Engineer. 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
The Hub5 is plugged directly into the new faceplate that has been installed - and i dont have any extensions or anything like that to confuse things.
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
Jon

i would suggest leaving it for 10 days see if things improve as they do say there is a 10 day training phase, if nothing improves after that then i would come back see if you can get a mod to help you out as they are a good bunch here all uk based

POOR SPEEDS INFINITY SLOUGH TODAY.

Hi All,
Anyone on the forum getting slower than usual speeds, ive just checked mine and its down to 18meg down and 16meg up, its normally around the 50+ mark, infact this is the lowest speed ive had since joining infinity 6 weeks ago, im using ethernet connection, i created a new connection straight into the modem to eliminate the HH3 and speed was the same.
I hope this is not a sign of things to come, i also checked my IP PROFILE again and its still saying 54.40meg/20, is this a sign of congestion or a fault somewhere.
Regards
MR-T.

Hi john46 and expert,
Many thanks for your comment i must admit i was shocked at how slow it is tonight, did another check a few minutes ago and it was 15meg down, 17.7up that is a major drop with the downstream being lower than the up, i do hope this is not a sign of things come, i now the speed testesr are not very reliable but even BTWs speed tester was only showing 16meg down and 9meg up.
As you said maybe a problem somewhere else thats causing the drop.
Regards
MR-T.

BT Infinity - Varying speeds and latency issues

Hi,
I have had BT Infinity 80MB since around May 2014 upgrading from my existing BT ADSL connection. I work from home and use VOIP via a softphone on my laptop. When I used ADSL I experienced no isses with jitter or latency and I could hold a crystal clear conversation. Since 'upgrading' to BT Infinity I am no longer able to sustain a clear VOIP call, voice is choppy. This is due to ping response times going through the roof. I set a continous ping to www.bbc.co.uk, every 30 seconds or so the ping response time/latency goes through the roof rendering the VOIP call unbearable (see below).
This isn't an issue with my laptop as I can use other wireless networks with no issues and I have tried whilst directly plugged in to my router. The router I have is a HUB 5, I have factory defaulted it but this is an issue with the line.
How can I get in contact with someone from BT to get this resolved? Everytime I go through the online help it never detects an issue with latency or speed. I have also tried the BT Wholesale test. I am currently getting 20MB....

Some of those ping responses are well out of range. One of the Moderators (who work for BT) should look at this.
Unfortunately a lot of people are / or have been experiencing such issues with the Infinity product (especially over the last month or so). Personally I believe there is either something fundamentally wrong in the BTWholesale backhaul, or that many exchanges are simply oversubscribed. Unfortunately technical analysis is rarely forthcoming on this site.
The first thing to eliminate is a problem with your line.
Try a quiet line test - details here http://support.zen.co.uk/kb/Knowledgebase/Performing-a-Quiet-Line-Test
if there is any noise the best advice seems tobe report it as a telephone fault rather than a broadband issue.
Other tests - if you have a Homehub 5 you might want to post the first 12 lines of your Stats (this will alert many of out-of-range line statistics).
I would let other posters pick up the thread at this point.
But if you're like me your line will be fine and the BTWholesale test will be fine but the problem wil persist

New Infinity User/Speed Question

Hi All, I`m another newbie in here and also to the Infinity BB as well.
So Hello and Good Evening to you all. :-)
I had my Infinity installed on Monday Afternoon without a hitch I am pleased
to say and I have been lurking on the forums reading up over the last week
or so checking out the pitfalls and wrinkles I am likely to encounter.
I know this is an on going chestnut on here from all that I have read but when I
was given a over the phone (by a nice BT lady employee) speed test (I have had a new line installed
before getting Infinity) I was told I would get 37.5 meg down and over 8 meg upspeed of which I
was obviously happy and impressed.
When the young man did a speed test on Monday I got a creditable around about 32 meg so that was fine.
I have been testing since then on and off and a few times its got back to 30 and over but mainly in the 20s
and teens.
Tonight I did a test at about 20:06pm and got just 6.96 meg down what is that all about?
The Up speed had been mainly around 7-8 so I down have a problem with that at all but what about my dowload speed, the homehub is wired into my PC.
What do you suggest I do next as I dont really fancy waiting until the 10 days as it seems a bit convenient that date I am committed for 18 months!
Any help will be gratefully accepted.
Andrew.

"Is that 15 sync or through put ?"
To be honest, I don't know.
I have been hovering around these forums for a couple of months, since Infinity came to my area, not sure whether to change over or not. I was forced into a decision when informed that my ISP was closing down (UKOnline), and I could move to Sky with 6 month free broadband. As I detest the whole Sky/Rupert Murdock organisation ........ here I finally am, on Infinity
Sorry, strayed a bit from the topic there. During this 'hovering' period, I swear that I've seen a post stating that 15 Mbit figure, but I cannot remember where it is, so cannot confirm or quote it.
Perhaps, based on the Speedtester results output, which states :-
For your connection, the acceptable range of speeds is 12000-38717 Kbps
That it maybe the sync speed rather than the throughput. Either way, they are BOTH low, if true .....
Cheers
Edit: @Monkey - I would regard sync speed as the speed negotiated between your router/modem and your ISP, and the throughput the actual speed OBTAINED when transferring files, taking into account the overheads of the protocols/methods used (losses)
Throughput always being less than the sync speed
When i was on ADSL2+ I would knock off around 15% for losses (overheads). So if I synced up at 12 MBits, I would expect to a get throughput of around 10.25 Mbits'ish, and this usually was the case. 12Mbits - 15% (1.8 MBits) = 10.2 Mbits. This 15% figure may not be relevant to Infinity, I would hope it would be less, but don't know.

BT Infinity 2 Speed dropped and now doesn't recove...

I've had BT Infinity 2 for a couple of years now and it has been working flawlessly. I use a Fritz!Box 7390 router and have had no problems at all with it.
That is until mid-January 2014 when I noticed by connection speed dropping down to less than 40MB/s and about 9MB/s on the upload. Now some may say that this is fine, and it does exceed my promised speed of 31MB/s by BT, which is true. However for the last two years I've constantly had speeds of 55-70Mb download and upload speeds of 13-18MBs.
Speedtest.net is reporting: 40Mb download and 10.3 Mb upload.
I do a lot of file transfers and remote server work so I notice the speed drop.
The Frtiz!Box reports some interesting statistics. Currently it is showing this:
Receive Send
Max. DSLAM throughput 44000 12000
Min. DSLAM throughput 22000 6000
Attainable data rate 46200 18176
Current throughput 43984 12000
Now I know for a fact that prior to this issue the Fritz!Box has been reportinging a Max. DSLAM throughput of 79000 and 20000 with an attainable data rate of 81000 and 24000 respectively. I suspect that there is something wrong either at the exchange DSLAM or with the line in between.
From the above figures it suggests that I am only obtaining BT Infiinty 1 speeds on my line and not Infinity 2. However my account says Infinity 2 and checking with the BT guys they report that there is no problem because I'm getting more than that promised 31 MB/s.
Frustrating as I know this has changed in the last three weeks. What's more suspecious is that I have the Fritz!Box sete to disconnect/reconnect every day at 4am. This means that every day normally I get a varying speed e.g. one day it might report 60/14, the next 55/13, etc. However since I've noticed this problem the line speed never changes, constantly reporting 44/12 with no fluctuation at all. This has been happening for about 3-5 weeks.
I just wondered if there is anything I can do now to find out where or really if there is a problem. BT 150 telephone support in India don't want to know because they say I'm getting more than 31Mbs.
Thanks,
Gareth.

BT Infinity low speed

Hi
Just joined so Hi to everyone. Reently had my infinity box moved from downstairs where I was using it wireless to upstairs where I now us ethernet cables. Wirelss signal was very poor becuase the house I live in is ancient and the walls are so thick. The speed was 32mbps which was good after moving at a cost of £130 tp me the speed is now only 17mbps?? Help appreciated.
Cheers

When the engineer installed and did a speed test from your line, what did he tell you?
You won't get anything faster than that.
Although the theoretical maximum speed is 40Mb/s BT actually say up to 40.
The actual maximum speed depends on how far you are from the street cabinet, and the quality of the phone line from the cabinet to your house.
The real average speed you get is further reduced by contention, ie how busily everyone else is hammering the internet.
But, the web sites you access may themselves present a bottleneck, so that Infinity may not actually feel any faster than before.
Maybe not the answer you wanted, but that's the reality.

BT Infinity - Massive Speed Drop !

I had BT Infinity 2 installed 12 days ago and have been more than happy with the performance..... until now. The connection stats below speak for themselves. The HH5 current connection status is first, followed by a speedtest last Sunday morning and a speedtest this morning at 11:30am. My IP profile is the same but the download speed has dropped by over 200% ! Should I reboot the HH5 and, if so, will DLM kick in and reduce my IP profile ?

I have now rebooted the HH5 and the IP Profile for the line has stayed the same at 77.43MBPS but the download speed is only 31.20MBPS which is way off what I had previously and should be getting.
