Re: 20Mb service, what speed should I expect?
 

Every downstream packet you receive has to be acknowledged. If the upstream is having problems some of those ACKs will be lost and the server will assume it has to resend the packet. Those duplicated packets are just wasting your downstream and show up as a fall in throughput.

Re: 20Mb service, what speed should I expect?
 

Hi soory to jump on the band wagon but i was wondering myself if i was getting the right speeds

Cable Modem Downstream
Downstream Lock : Locked
Downstream Channel Id : 0
Downstream Frequency : 331000000 Hz
Downstream Modulation : QAM256
Downstream Symbol Rate : 5360.537 Ksym/sec
Downstream Interleave Depth : taps32Increment4
Downstream Receive Power Level : 10.8 dBmV
Downstream SNR : 33.9 dB

Cable Modem Upstream
Upstream Lock : Locked
Upstream Channel ID : 1
Upstream Frequency : 18800000 Hz
Upstream Modulation : QAM16
Upstream Symbol Rate : 2560 Ksym/sec
Upstream transmit Power Level : 44.5 dBmV
Upstream Mini-Slot Size : 2

I have noticed that it's seem to be slow or it could be my imagination

cheers sonic

Re: 20Mb service, what speed should I expect?
 

Downstreams a little too high, nothing to worry about

Re: 20Mb service, what speed should I expect?
 

Thanks great, so i'm getting the best out of it then :)

Re: 20Mb service, what speed should I expect?
 

Thanks for the reply.


I know virgin tell me that using a speed check site like http://www.mybroadbandspeed.co.uk/ is no proof of speed but I've been doing twice daily checks now for a months with it and getting results of

19635 kbps (2.45MB/s) Down
and
725 kbps (90.6kB/s) Up

as an average. However since I saw a Virgin bod working on the Cab at the end of the road on monday I'm now getting (as an average)

9000 kbps (1.13MB/s) Down
and
716 kbps (89.5kB/s) Up

I know there is not much of a difference in the Up speeds but the Down are at 50%

Any ideas please?

Re: 20Mb service, what speed should I expect?
 

Virgin ask to you to use londonserver on speediest.net your assuming the speedtest site is fine when that infact could be congested.

Re: 20Mb service, what speed should I expect?
 

The only speed test I use on a call is http://www.virginmedia.com/testmyspeed/manual.php which includes full instructions how to calculate your speed.

Interesting

Re: 20Mb service, what speed should I expect?
 

OK, tried that and got

505kb/sec
511kb/sec
488kb/sec
511kb/sec

= 2015 +201.5 = 2216.5kb/sec

from 20meg connection

Re: 20Mb service, what speed should I expect?
 

Just to confirm my score using the above is 8Mb over a 3min peroid, will try at a few other times too out of interest. I still havent had chance to call yet, I wanted to avoid evenings due to the high risk of getting the 'offshore' helpdesk again :mad:

Re: 20Mb service, what speed should I expect?
 

Im having the same problems with VM on 20Mb service, always got full 20Mb, but last few months bout 6-7 months been getting anything from 1Mb-12Mb, switched to Sky now, all will be installed next week, no point paying £35 for 20Mb service when i could pay about £30 for everything!

Re: 20Mb service, what speed should I expect?
 

Guess these figures are KB rather than Kb? If so you are clocking about 18Mb so pretty good and im envious! Seems some people are getting the bandwidth they pay for.

Re: 20Mb service, what speed should I expect?
 

Sky broadband lite?
