Speed test giving erroneous results

I recently came across a broadband speed test. I have two computers that I use on a regular basis, one of them is in my bedroom and is connected to my BT Hub 2.0 by about 20 feet of lan cable. When I test the speed of my internet on this particular computer it gives me various results depending on when I test. Normally it gives me a result of less than 2 MB download speed, sometimes just less than 3 MB. However, I tested it on my other computer and I couldn't believe the results. The two tests I carried out back to back gave me results of 31 MB download, and 28 MB download. To be quite honest, I don't think these results are correct because as far as I know, BT Internet only provided download speeds up to 20 MB. So what the heck is going on?

The best tester is BT's own at : http://www.speedtester.bt.com/
Reason being, it falls within the BT network boundary layer, and is less influenced by other issues, that affect net based testers.
It should be the tester of choice, as Ian as implied.

Moving soon, speed checker giving odd results

We're currently buying a new house, and I was looking at transferring my Infinity to the new house - but the Speed Checker is showing Infinity as unavailable. By mistake, I entered the house next to our target, which is on the same telegraph pole, and it comes up as available for that house. The others on the same pole don't.
Then I looked around the corner, and the adjacent roads have full speed infinity. It seems odd that a single pole has different enabling status for some houses.
Is there any way to find out why the provision is different? If these are non-standard lines, direct to the exchange, then I would have thought that it would be a BT cost saving to revert them to "standard" provision - assuming of course, that the cabinet isn't full...

Blast speed is currently 2 Mbps/9 Mbps on the Comcast Speed Test. Help please!

I've had the Blast service for quite some time, and have noticed painfully slow internet browsing for the last couple of months. I mean...pull-my-hair-out-slow. I just did a Comcast speed test and the results were 2.31 Mpbs and 9.01 Mpbs. Um....that would explain things. But not really... as I'd love to see the speeds I'm supposed to have. Even double digits would be nice! I'm trying to run ShaperProbe but I get the error "Servers are busy. Try again later." I've tried a few times. I'll post the results if I can get the scan to work. Power level is 45-46 dBmV and SNR 35-37 Modem: ARRIS Motorola SurfBoard SB6141 DOCSIS 3.0Logs of June 2015 (the most recent, and the logs before that are January): Jun 22 2015 07:07:243-CriticalT05.0SYNC Timing Synchronization failure - Loss of Sync;CM-MAC=b8:16:19:fa:b8:0c;CMTS-MAC=00:1d:70:af:fd:a0;CM-QOS=1.1;CM-VER=3.0;Jun 18 2015 08:04:503-CriticalR02.0No Ranging Response received - T3 time-out;CM-MAC=b8:16:19:fa:b8:0c;CMTS-MAC=00:1d:70:af:fd:a0;CM-QOS=1.1;CM-VER=3.0;Jun 18 2015 07:08:273-CriticalT05.0SYNC Timing Synchronization failure - Loss of Sync;CM-MAC=b8:16:19:fa:b8:0c;CMTS-MAC=00:1d:70:af:fd:a0;CM-QOS=1.1;CM-VER=3.0;Jun 17 2015 23:08:553-CriticalR02.0No Ranging Response received - T3 time-out;CM-MAC=b8:16:19:fa:b8:0c;CMTS-MAC=00:1d:70:af:fd:a0;CM-QOS=1.1;CM-VER=3.0;Jun 16 2015 02:43:065-WarningZ00.0MIMO Event MIMO: Stored MIMO=-1 post cfg file MIMO=-1;CM-MAC=b8:16:19:fa:b8:0c;CMTS-MAC=00:1d:70:af:fd:a0;CM-QOS=1.1;CM-VER=3.0; I would sure appreciate any ideas. I have not contacted tech support yet, although that may be faster?? We'll see. Thanks in advance for any help!

ShaperProbe has not been usable for some time, unfortunately. Check to see if Comcast is reporting an outage for your area by logging in to https://customer.xfinity.com/Secure/MyServices/ or by checking the voice response system at 1-800-Comcast.
If no outage is reported, see Connection Troubleshooting Tips. If you want to troubleshoot this yourself and still need help, please provide Information Requested for Connection-Related Posts.
If you are using Wifi it's best to switch to an Ethernet connection if possible while measuring speed and checking the reliability of your connection to Comcast.
If you'd rather have them do the troubleshooting call them at the phone number on your bill or 1-800-Comcast and have them send a tech out to identify the cause and correct it.
If the tech finds bad coax, splitters, amplifiers, or connections in your home (even if Comcast originally supplied them) you'll probably have to pay for the visit unless you have their Service Protection Plan (http://www.xfinity.com/spp/, about $5/mo). If the trouble is due to a faulty Comcast modem, eMTA, gateway device, or anything outside your home, you shouldn't be charged.

Slow page loading even though speed test is fine

Hi all, I have noticed that pages and content are very slow to load over the last few days. I ran the speed test and the results are fine (37mb down 8mb up). I thought it may have been Firefox because it can play up. After testing with Chrome and IE9 I can confirm it is definitely not right.
Anyone else having problems? I am on the Macclesfield exchange. Connected via ethernet directly to the HH3.

Infinity fitted Tuesday. 37.8mb down, 1.8mb up. Pages are slower to load than before my upgrade ! As a non techy with computers, you must excuse any embarrassing blunders with technical issues, but, I have found if I use AltaVista instead of Google, everything is fine. If I type fast into the search bar on Google it can't keep up with me ! If I try to deleate the www entry a character at a time, it goes in fits and starts as it receeds back across the screen. I had no problems with the site till the upgrade. Is it just a problem with Google and the increased speeds or is that too simple an answer !!

Message Mapping vs Interface Mapping test tabs giving different results.

Hi all,
I am developing an interface that always requires an output file to be created (even if there is no data). I have found a way to change my select statement in the JDBC sender to initiate the message even if there isn't any data (using UNION select -1 ID, '' col1, '' col2, etc.) and that seems to work fine. I then put logic in the message mapping to suppress the row that contains the -1 ID value, which would result in an empty file when there is no other data, and should result in a file containing only the correct data when there is data.
So, my problem: I am always getting empty files with this logic. I tested the logic in the message mapping test tab and it worked perfectly, however when I test it using the interface mapping test tab it results in what becomes an empty file!
My source and destination structures are fairly simple:
Root
--row
ID
col1
col2
The logic I use to suppress the ID = -1 row is:
=removeContexts([]ifWithoutElse([keepss=true]Not([]equalsS([]ID, Constant([value=-1]))), SplitByValue([type=Each value]row)))
Obviously, I'm stumped - any help would be appreciated!

Hi Mike,
Can you quote the error log..u r getting error in message mappin or interface mapping?
Please suggest the test results for both the mappings.

Brand new user of Extreme and express - surprising speed test results

Dear All,
I had been using a linksys wireless router connected to a 20mps cable connection to send a wifi signal around my home. After a fair bit of research I upgraded to an airport extreme (wanted benefit of the gb ethernet ports and simultaneous dual band which the linksys did not have.)
So airport extreme set up nicely and speed test.net says I have download speeds of 19.23mbps on both my ipad and my macbook pro (2010). Signal does drop off in one part of the house so after a chat with the apple sales guy I also picked up an airport express to use as an extender. Using the excellent advice on this board mostly from Bob Timmons (found on a search) I was able to set express up and place in the part of the house where the signal didn't previosuly reach. It worked. So far so good. But, then an issue.
When the express is plugged in mbps on speed test drops from 19mbps to 4mbps on both the macbook pro and the ipad. Switch of the express reconnect the devices to wifi (I guess now they are focussing on the airport extreme) and speeds return back to the 19mbps!. Why would this be? And is there any way to fix it? The extra range is useful but not at the expense of all that speed.
thanks
Josh

Setup looks correct.
Have you tried some different channel settings to see if another channel might work better?
For 5 GHz, you would want to choose one of the higher numbered channels 149, 153, 159, 161 and make sure that "enable wide channels" is checked in Wireless Options.
For 2.4 GHz the lower numbered channels are usually more crowded, so you might try one of the higher numbered channels for that band, maybe 9, 10, 11.
Apple routers seem to be very sensitive to interference. If you have a cordless phone there, try powering it off for 45-60 minutes and restarting the Extreme and Express to see if that makes any difference.
If you have time, you can scan to see what other networks are working around you with a utility like iStumbler.
If you do this, you may be surprised that "full bars" is not as much signal strength as you might have thought. The "bars" are there pretty much for show. They really don't tell you much about the real signal strength on the network and they don't tell you anything about noise on the network, which can drag down speeds.

Speed testing proceed with caution??

I've been fascinated by the various reports of variable speeds being seen on various different speed testing sites, so I've been having a play, and the results have been, shall we say, interesting.
Let's start at the top. No matter which machine I access it from, http://www.speedtester.bt.com/ shows me 56megs down and 12.89 up, with a max achievable of 60.1/20.
Namesco's ( http://www.speedtest.bbmax.co.uk/ ) shows 33623/14734 on my "work" partition, but if I reboot into another partition which is set up for webcasting, it, too reports the full 56megs down and 14/15 up. Same connection, same wires, barely five minutes apart on Mac OS X 10.7.3 in both partitions.
If I then, boot back into the work partition, and bring up Speedtest.net not only on there, but also on a couple of other machines, and set them all to check simultaneously, the combined total of the download speeds is - guess... yup, 56megs down and around 14 up.
Aside from quite fancying my connection giving me that full 20megs up (OK, I know, it'll be 19 or so), I'm really quite happy with this - and it does point out that, in all likelihood, severely fluctuating speed tests may not necessarily be line-related. If I wasn't able to reproduce all of this more or less at will, I may have thought differently, but it's an entirely repeatable excercise.

Yes indeed, none of the speedtests are reliably accurate all the time as their servers and routes to the server are subject to varying conditions. Speedtest.net is very dependent on which server you select, as their automatic server selection chooses based on ping results, which does not always give you a server with the fastest data rates (my results vary from 35 to 70Mbps, or as low as 2Mbps if you go out as far as New Zealand ). BT's main http://speedtester.bt.com/ (diagnostics) is up the pole for most of the day and is only any use for finding out your profile. However, their beta test is pretty good and is always worth trying: http://speedtester.bt.com/beta/speedtest-remote.jsp
BBMax is often said to be the best one but that could just be because it uses a much smaller download file and the test lasts for a shorter period of time. That means there is less scope for varying line and server conditions to intervene, and for Internet Security programs to slow things down.
So what I do is:
a) Turn off my Internet Security program (this can be very important)
b) find the fastest speedtest.net server and use that result
c) use BT beta speedtest (as I already know my profile)
d) check BBMax
The results of these three methods are nearly always between 69.x Mbps and 71.x Mbps, my profile is 72.8 Mbps. I don't think you'll ever get your 19Mbps upload by the way as I am on a 20Mbps cap but the fastest upload speed I've seen is 16.x binary Mbps and 17.x decimal Mbps.

Internet speed test app

Is their a good internet speed test app? I have "Speed Test for iPad". It gives such inconsistent results that I don't trust the results.

I have Speedtest XHD. seems to work pretty well.
As for inconsistancies, depending on how you are access the internet - and how you define inconsistant - you should count on it. Any app measuring this is going to be giving you a snapshot in time. and it will vary from test to test sometime by quite a bit.

Accuracy of Verizon Speed Test

I am wondering about the accuracy of the Verizon speed test. I have the 75/35 service and I am testing today around 10/15 on several test sites...except Verizon. The Verizon site, in the past and today, ALWAYS tells me the speed is what it is supposed to be. I find this very strange.
I typically use speedtest.net and have logged results from 75/35 to what I have today.

If you really want to know your true day to day speeds sign up for www.samknows.com I'm subscribed to SamKnows that is a free resource for consumers and volunteers. Their goal is to embed software suite into internet enabled devices to build the most accurate picture of global broadband performance. I am a participant & I get a report card that measures my speed etc....
They are contract by the Federal Communications Commission (FCC) to research and collect data on American fixed-line broadband speeds delivered by Internet Service Providers (ISP's) - until now, something that has never been undertaken in the USA.
99.9999999% of the time get faster upload & download speeds... I had Optimum before & they don't even come close to the performance or reliability.....

Difference between Transceiver Statistics vs. Speed tests

We had been having problems with our DSL speed today. We discovered (obviously) that most of the problem was that my son was watching Netflix on our TV (through an app directly on the tv, not through a game console), which was sucking up most of our bandwidth.
But, while testing things out, we checked our Transceiver Statistics. We are getting about 3300 mbps download, but after running two different speed tests (speedtest.net and bandwidthplace.net), it seems we only ever really get about 1.5 - 1.6 mbps. This was after turning off the Netflix stream, by the way. This is basically our normal speed.
At any one time, we have 2 laptops and 2 Android phones connected to our network through a Beklin wireless router, as well as a desktop connected to the Belkin router through an ethernet cable. The tests have been consisten regardless of the number of computers running at the time, as long as they aren't doing anything with a real network load.
I don't think it's a problem with the router, because we can copy files between the computers at about 4 megabytes per second (36 megabits per second). Althought the WiFi connection says it's running at about 130 megabits per second. Maybe that's an issue with disk speed, I don't know...
Anyway, is there anything weird going on, or is it a symptom of outside network load that our speed tests are roughly half the value we see on the Transceiver Statistics for the modem?
Here is the full details from our Westell modem Transciver Statistics:
Transceiver Revision: 7.1.254
Vendor ID Code:        4
Line Mode:               G.DMT-Mode

Solved!
Go to Solution.

The transceiver stats only measure the speed of the connection between your DSL Modem/Router and the Central Office Equipment. You can get the full 3mbs downlink speed with losses a lot higher than 42db   I have seen it above 60db and still providing 3mbps.
However the link between your modem and the Central office is only small part of the total path between your computer and whatever internet site you are connecting too. Speed tests measure end to end, as opposed to only a small part of the message path. As a result speed tests almost always show lower performance than transceiver stats.
The best analogy is Verizon effectively only provides the on and off ramps to the Internet Superhighway. Just because the local ramp is clear is no assurance there aren't traffic jams elsewhere on the highway. The problem with most speed tests is you have no idea how your traffic was actually routed, and what constraints may be placed on it by parts of the network that Verizon has no control over.
The transceiver stats represent the best possible case. The reality is there is no shortage of issues upstream from the central office, either on, or off the Verizon network that can restrict your actual speed to considerably less than 3mbps. It is unlikely that your wiring inside the house is an issue, if it was, you would be seeing a downlink speed at less than 3mbps.
However your uplink speed seems slow. The nominal uplink for the 3mbps tier of DSL service is 768kbps, not 512kbps.

Difference between BT Broadband Speed Test and all...

I have recently moved to BT Broadband from TalkTalk as I was dissatisfied with the speeds that I was getting with my TalkTalk line – they were OK outside of peak time but woeful in peak time. With TalkTalk, I was on their ‘up to’ 8Mbps which, in practice, translated to about 6Mbps for download outside peak times but dropped to below 1 Mbps in peak (around 500Kbps and sometimes even lower!) – these measurements were taken regularly with both the TalkTalk and Think Broadband speed tests which were usually roughly in agreement and I haven’t had to rely on memory as I downloaded the spreadsheet records available to Think Broadband registered users.
I am now posting this in the hope that somebody can explain the difference between the BT Broadband Speed Checker (Here) and all the others available on the web.
When you are first connected to BT Broadband they warn you that your speeds will vary over the first ten days while they test your line to ascertain optimum speeds for it. During that time, I checked it every day early, mid-day and evening (usually around 0630, 1230 & 2000 hrs) with Think Broadband and, yes, it did vary – the first day it started at around 1Mbps for download but rose to 10Mbps by the end of the day. On the second day, it rose to a peak of 17.8Mbps which was unbelievably fast to use (well, to me anyway) but never reached that speed again as over the rest of the ‘test period’, the download speed dropped and dropped to the point where I am now outside of the BT test period and consistently seeing only 2 to 2.5Mbps over a 24 hour period.
I emphasise that those speeds were all recorded using Think Broadband but I am now doing tests using the BT checker mentioned above and the speeds which BT indicate for downloads are consistently in the 14 to 18 Mbps range. If I do the BT and TB test in quick succession, they generally show the BT calculated speed to be better than that of TB by a factor of around 7 (ie. TB at 2 Mbps whilst BT show 14Mbps). Now either they are measuring different things (or the sams things differently) or one of them is lying – all I know is that my general browsing experience is slower outside of peak times and I can tell by the time it takes to load pages.
I might have misunderstood something in these tests but I am now beginning to regret that I fell I for the BT sales pitch which promised me ‘up to’ 20 Mbps but ‘more likely’ 17 Mbps. I have tried to discuss thisl with BT Broadband technical support but they were no use whatsoever – indeed, I got the impression that he was reading from a script and as it didn’t cover my issue, I was wasting my time – it would also have helped for English to be his first language!
According to the BT test, I am well within their ‘minimum guaranteed access speed’ (Here). for my area (about 4Mbps) and therefore cannot do anything about it. BUT that is only when measured using the BT speed tester – with any other, I am well below. I am beginning to feel very conned and might even start looking to withdraw from BT if I cannot get this settled.
Can anybody help. I will happily post detailed records of my various tests or router stats if they will help.
Thanks in advance.

Speed Tests

Could someone point me to a decent test site to do speed tests against what my ISP have said I could theoretically achieve??
Also in directing me, could anyone clearly explain what the results actually mean (downstream / upstream??)
Thanks

Flash Player only partially opens my ISP's speed test

I am having trouble with line speed and download speed. My ISP has directed me to their speed test, which has to be done several times and submitted before they will investigate.
I have tried to use the test several times on my networked pc and the flash player plugin will not complete the download of information.
I have reinstalled Adobe flash player several times with no change.
I have temporarily disabled my firewall with no change.
I can use the speed test on a netbook connected by wireless to the same network

The videos that DO work are most likely HTML5 which requires no plugin.
Spotlight search "Flash Player.plugin" and trash EVERYTHING in the results.
Go to: [user]/Library/Preferences (Hold the "Option" key when you click "Go" from the Finder menu to access this folder)
Trash the com.macromedia.Flash Player.app.plist file.
Trash the Macromedia folder from there as well (the WHOLE folder).
Go to: Mac HD/Library/Application Support/Adobe
Trash the Flash Player folder and the Flash Player Install Manager folder.
Go to: Mac HD/Library/ Internet Plugins.
Trash the flashplayer.xpt file.
Empty the trash.
Download the offline installer: http://fpdownload.macromedia.com/get/flashplayer/current/licensing/mac /install_flash_player_11_osx.dmg and run it.
If after all that, it still doesn't work, we'll need to look at other plugins you have that may be causing a conflict.
I have Safari, Firefox, Opera and Chrome, as well as a few "off brand" browsers and Flash Player works in all of them. Late 2012 Mini, Core15, 16Gb RAM.

Has anyone done 3G speed tests yet?

I assume all the problems mentioned here will get worked out in short order, but I've seen nothing here comparing 3G speeds to Wifi speeds on these new units.
If anyone has done some test along these line, could you post results?
Thanks--

I know some people have been having problems with the 3G but I have been very happy with it so far. Setup took about 30 seconds yesterday. Initial speeds were around 1.8 Mbps download, then later slowed to around 1mbps, likely due to all the demand. Every speed test I ran showed the iPad to be at least 20% faster than my iPhone 3G. Around midnight it began to speed up as people went to bed - at one point I had 3.2mbps download, which is excellent considering AT&Ts max theoretical speed right now is 3.6mbps. I have never had a speed over 2.2mbps on my iPhone.
Today I was using it in the car on a route I often take. One area along the drive is an AT&T dead zone - my iPhone always drops to "No Signal" as do any other AT&T phones. Despite this, my iPad held on to 4 bars and managed a 1mbps speed test in the heart of the dead zone. I also have found the WiFi on the 3G model to be slightly stronger than the wifi only model, presumably due to the plastic top which breaks the aluminum case.
I for one do not have any problem with AT&T restricting some of the video apps. The iphone was the same way and I wasn't expecting the iPad to be any different. All in all I am extremely satisfied with my purchase.

What is your fastest BT Wholesale Speed Test resul...

Hi,
Aplogies to the CL's if this is not the right forum but it definitely is speed related related. I tossed up where to post it but decided on here fuguring you will soon move it if you want to.
As the title suggests, and for a bit of fun, what is the fastest result you have got from the new BT Wholesale Speed Test ?
I'll kick off with this :-
Best regards,
dfenceman

Hi Keith,
I typed a long response but have lost it now ???
Right, I'll type it all again. You are right I am on ADSL as is the whole village. This result was obtained from the village school.
As you know, every speed test I have run on the "new" speed tester has returned a download speed in excess of my IP Profile and at times in excess of my downstream speed.
Under the County Councils cost saving, performance enhancing project the school has just had its wireless link replaced with 16 bonded copper pairs. This was projected to provide the school with 8Mbps, 2Mbps below all the other 250 odd in the county. I therefore asked the school to run a speed test to find out what it is actually getting and this was the result.
I thought it would provide a little light relief from what can be a very serious forum.
As I said in my OP I was unsure where to post it but I never expected you to move it ti Infinity, I thought it might be The Lounge. Neith of these are visited so frequently as the Speed/connection forum though.
Best regards,
dfenceman
