dead slow download rates

[alan.ralskey]

hiya

i have a 150k bb connex.

am currently downloading a 1.7Mb file.

I have a transfer rate of only 451b/s

It says that it is expecting to take another 35 mins to download this file.

this is obviously not right.

any ideas what is going on?

[peterska2]

sorry i was using the wrong ID then.

my d/l rate has now fell again to 300b/s tho

please help

[peterska2]

now fell again to 225 b/s

1st 128K took 0 ms = Infinity Bytes/sec = approx Infinity kbits/sec

4th 128K took 60 ms = 2184533 Bytes/sec = approx 18175 kbits/sec


something tells me that's not right.

i'll run it again

[peterska2]

here we go

1st 128K took 19610 ms = 6684 Bytes/sec = approx 56 kbits/sec
2nd 128K took 19110 ms = 6859 Bytes/sec = approx 57 kbits/sec

[peterska2]

that doesnt look healthy to me :(

[peterska2]

now I am losing my pateince with it.

At 11:55 when I started my download it said that it would take 15 mins. Then it said 35 mins at 12:05. At 12:25 it said 30 mins. Just checked on it again and it nows says 60 mins. My transfer rate is at 250 bytes/sec.

Just done another speed test and got

WTF is going on?

hears mine:

4th 128K took 17850 ms = 7343 Bytes/sec = approx 61 kbits/sec

i think that is normal.

this is what a 150kps speed test should look like -

Without knowing what uBR you are on, what your current IP is, what your MAC is, or any 2 of the above it's pretty much impossible to offer any insights.

The download rate is well below par, it's unlikely though that a download running as low as 350 bytes/s is the fault of ntl.

Would also suggest that it's a fault fairly specific to you going by the lack of other people on here posting + complaining about the issue.

[EDIT] Removed a few extra bits

[grum1978]

i take it you tried rebooting the modem KA?

Andre is right in what he has said abt it defaulting to the 64k service

[XFS03]

If you have download speeds in the 60's, I would check a few things first, before phoning ntl.

If you have an Ambit modem (ntl:home 100/120), you can check which service your modem is configured for, by going here:-

http://192.168.100.1
(password & username = root)

Clicking on 'Operation Configuration' will show you which service you are on, under 'Maximum downstream Data Rate'.

Then I would check that windows is set up properly for your BB speed by going here:-

http://www.dslreports.com/tweaks

and running Tweak Tester II to see if your RWIN is set correctly. If not, download DrTCP from the same site & set RWIN to a value it recommends.

[peterska2]

yes i have rebooted the modem.

will be ring TS later unless anyone has any better ideas

[Ignition]

Follow Grum's suggestion and see what service speed you are on.

If it's the 64k service I would suggest switching modem off for as long as you can bear to be without it and switching it back on again + see if that gets you the proper DHCP and config file - what are the last 4 digits of your IP address at the moment, are they by any chance .248 or higher? (Not 100% sure it's 248 but is somewhere around there) :)

[peterska2]

.214 for the last bit of my IP addy.

[ntluser]

Just did the test as suggested and I got:-

1st 128K took 1810 ms = 72415 Bytes/sec = approx 602 kbits/sec
2nd 128K took 1810 ms = 72415 Bytes/sec = approx 602 kbits/sec
3rd 128K took 1810 ms = 72415 Bytes/sec = approx 602 kbits/sec
4th 128K took 1870 ms = 70092 Bytes/sec = approx 583 kbits/sec

Apart from the 4th test , all the others seem OK or have I misunderstood the figures?

No your test looks spot on for a 150k ;)

:rofl: :rofl: :rofl:

na seriously 600k results seem nice:D

I just ran the test again before I think about ringing TS

I still get these

And I have rebooted my CM again

[peterska2]

Ta for the number Andre

Do you think they will phone me back?

[peterska2]

TS for SACM is actually 08456500925

[grum1978]

No they will not call you back KA :(

[peterska2]

ta grum. i is on the phone to them now

[peterska2]

rang TS and they dont know what is up. everything looks fine from their end.

[peterska2]

well i just canx my DD the same as I do with my telco bill then. I dont care really.

No the results are too slow for 150k service try rebooting your modem and follow other advice given on this thread if that doesn't improve things

let us know how you get on

[tabatha]

Thanks Grum..Have followed other advice re tweak test...altered??rwin?? to the suggested num..6300..said ok...re-boot???is this unplug/replug??how long for??the numbers,kbit/sec have been getting slower over past week...cheers

[tabatha]

Thank you my Lord......

[grum1978]

yes unplug your modem and turn your pc off, turn your modem back on wait for the lights to go steady then power up your pc.

leave it unplugged for abt 30 secs i guess

[tabatha]

Hi Grum..your post 37..run that past me again pse...when I unplugged modem comp froze..had to use restart button..speed test now mid 30s!!!!what did I do wrong

[grum1978]

No problem....

What i meant was turn off your modem and your pc
unplug your modem for abt 30 secs
reboot your modem and wait for the lights to go steady
restart your pc
do a speed test

if you are getting worse results ring technical support and see what they say :)

[tabatha]

grum...your ins clear...BUT.when I unplug modem..no switch as such,I pull the plug out of the back..the pc freezes..can I do reverse and switch off pc first...win me...120 modem with USB

[grum1978]

yes you can do it that way if its better for you

[peterska2]

120 modem tabatha?

that's what mine is too :eek:

[XFS03]

peterska2 did you try the 2 links in my previous post?
If ntl say they can't see any problems, it could be down to your PC setup.

[peterska2]

I use ethernet rather than USB. They told me that the speed test results are meaningless when I rang them earlier. I should really try downloading something and see how it works tonight but after last nights fiasco I really can't be bothered with the hassle.

[kronas]

try this download peterska2 tell me what the max speed is that you get make sure you are not trying to upload or download while your d/l this

[peterska2]

downloading at 18kb/s tonight kronas

in that case your connection is fine your on 150k someone correct me if im wrong :p :D

[peterska2]

yeah it is tonight.

dont know what was happening last night tho.

gonna run another speed test out of curiosity

[Richard M]

For 150K, that's right.
I assume that you are using M$ IE to download so that sounds fine.

Next time, run a virus scan because a trojan could be using up your bandwidth and close any programs which use the net.

i still get this on my speed test tho

not worrying about it at the mo. if it grinds to a halt again then I'll come back to it.

If I can come in here...started at 45...very quickly down to 18/18.5...but was not going to wait 1hr 15 mins to complete!!...thanks kronas..will check for comments 2morrow...really is good nite time...

[kronas]

i think you should ignore the speed test if your d/l at 18kb/s because thats spot on

sounds right too goodnight :)

i benchmark my speeds based on that link :p

[peterska2]

so its just the speed tests giving us duff info then

*phewy

[XFS03]

peterska2...the info for your speed can be found by clicking on 'Operation Configuration' and looking at 'Maximum downstream Data Rate', when using that first link.

As for the Tweak Tester results, it probably told you, on the left-hand side of the result screen, that your RWIN is too high. From my own experience, having RWIN set too high gives erratic download speeds but doesn't give consistently low speeds.

Anyhow, it seems after all that, that there may be a problem with the speed test, since I also download around 18kBytes/sec, but the speed test gives me results around 140-150kb/s. Strange.

You could try another speed test. I often use www.pcpitstop.com

Having said that, I tried robin walker's speed test tonight, and it gave very similar results to pcpitstop.

Edit: and that fits with the 80Kbytes, I got from Kronas's link (600 service here)

Maybe XSF03 thought it was strange that he would get 18KB off your link, and 150 kb from the speedtest when peterska was getting 18 KB and 50kb.

Sorry...didn't make myself clear.
What I was trying to say was, I get a download speed of 18kBytes/sec, as indicated by windows, when downloading files, which ties in with my speed test results of 140-150 kbits/sec.

It's strange that peterska2 & tabatha also get an indicated 18kB/s from the windows download indicator, but only get a result of around 60kb/s when using Robin Walker's speed test.

I find it strange as well. Speed tests may be inaccurate, but a factor 3 difference between the windows download indicator and a speed test is more than inaccurate. My feeling is that something must be amiss (be it local settings for peterska & tabatha) or some issue that is affecting their downloads from the speedtest site, but not from blueyonder.

Hi..As a footnote to my postings on this thread I have outlined the steps I have taken,in the hope they may be of help to others with a similar problem.....
Speed test on .co.uk home page showed d/load speeds of an average of 55kbits/sec
Tried modem reboot...no diff.
spent 20+mins on fone to BB tech support,who went thro all my comp settings,altering many.T.S.asked me to go to pcpitstop..manual d/load of 141kbits/sec..
Tried d/load as suggested by kronas...about142kbits sec
Today I have tried speed test again with pcpitstop....
Manual..141..auto..150...
Minutes ago tried speed test on home page...ave56kbits/sec..
Would appear the home page test is not compatible with all comps/settings...others have had similar speed results...
As I said,this is posted to maybe help others..I have no axe to grind...many thanks to all who posted advice...VERY MUCH APPRECIATED....

It may not be the BB that's at fault, but the "virtual circuit" between your computer and the source.

Personally I use Download Accelerator Plus which, where possible, opens up multiple links between you and the source and/ or any mirrors available and downloads file "chunks".

This means that if one link is running slow, the others take up the slack and aren't held up by the laggard.

You can download a free version from http://www.speedbit.com
