30MB just installed, poor performance. Perhaps worse?


[link to this post]
 
Hi Folks,

I hope I can get some advice regarding my recent Virgin Media upgrade from 20MB to a 30MB line. I'm fairly technical at work but here i'm a noob.

It does work at speeds approach my old 20Mb line but it doesn't seem like an upgrade, if anything it's worse.
And even worse, the fare usage policy throttler appeared to kick in even sooner then usual!!! (Is this possibly because i'm on the 50MB network now?).

- I'm just across the road from the cabinet.
- I was provided a new SuperHub.
- The engineer was well meaning and disabled IP Flood Detection and the Firewall service suggesting he had seen up to 75% packet lose with them enabled.
- The engineer did seems puzzled with the dB power when he was here.

- Previously 16.5Mb on the 20Mb line.
- I have now scored as low as 6.5Mb repeatedly on the new 30Mb line but this afternoon i scored 14.9. TB Speed snapshot: http://goo.gl/1849C

- Power levels seem to be refereed to a lot on the orum, SuperHub Connection stats snapshot: http://goo.gl/T17er
Modulation Channel ID Max Raw Bit Rate Frequency Power SNR Docsis
QAM256 96 55616000 Kbits/sec 298750000 Hz -4.4 dBmV 39.4 dB Hybrid

- TBMeter 200Mb download test snapshot: http://goo.gl/Z31l2


I hope i can get some advice from the Gurus. I'm a bit out of my depth and need some grounding for complaint if i'm to go back to VM. I guess the rely on people ability to qualitatively query them to avoid support.

Thanks

I have just upgraded from 20Mb to 30Mb as well. I would never get more than 7Mb download, but more typically it would be around 4Mb. It’s now running at 9.6Mb – that’s the good news. However it took three attempts to get the test to complete AT ALL.
Appalling advice from the Virgin Help Desk, who had problems registering the new modem - “take your computer to a shop and ask them to update the drivers”. The circuit burst into life after around 30 minutes, so give it time before calling.

I get 17mbit on here, but 30mbit on speedtest.net london server as well as real world ftp performance.

so there seems to be a performance issue between tbb and VM.

the TBB speedtest doesn't work on the virgin 50Mb service, and probably the 30Mb as well. speedtest.net will give you a more accurate reading.

(my reading below is from almost 2 years ago, when the speedtest used to work)

I'll triplicate that advice. I've no idea why but TBB always gives poor results on my 50Mbps while speedtest.net and real world downloads show it performing close to advertised rate most of the time.



If you can't fix it with a hammer you've got an electrical problem.

Thanks Folks.

I ran some more tests in the past two days, I think both are associated

http://speedtest.net.uk/result/25691/ - 29.7Mbps
http://speedtest.net.uk/result/25693/ - 10.16Mbps
http://speedtest.net.uk/result/25694/ - 7Mbps
http://speedtest.net.uk/result/25695/ - 5.9Mbps
http://speedtest.net.uk/result/25712/ - 6.39Mbps
http://speedtest.net.uk/result/25719/ - 30.26Mps .... really... i don't get this at all.

http://www.speedtest.net/result/1145356870.png - 29.89Mbps.
http://www.speedtest.net/result/1145367414.png - 17.4Mbps
http://www.speedtest.net/result/1145372245.png - 7.96Mbps
http://www.speedtest.net/result/1145375717.png - 25.5Mbps
http://www.speedtest.net/result/1145379549.png - 12.74Mbps


- The Fair Usage policy does appear to be being applied properly after further testing. I' ot sure what happened on the first couple of days because I didn't approach the limits described.
- I did manage to achieve some high throughput lastnight, possibly approaching the 30Mpbs honesty limits.

Still, i'm conflicted about the inconsistencies.
Any advice?

retest with the london server as we know that one is on a gigabit port, many of them are only on 100mbit ports. If london varies its most likely congestion on your UBR port. (VM problem).

+1. London is the only reliable one for me.

I have just self installed my 30 meg superhub. I did have to switch on and off twice to get it to work,but just now i g0t 31.6meg so I gues that I am actually limited to 32 as I seem to bump up to this on the several occasions I have speedtest.net.
I do not use the wifi. I have had mine for a week now with no probs at all..
I am sorry that you get a bad service and hope it all works out ok for you

Hi Folks.

Firstly, thanks for everyone help.

After some further testing I can confirm I am receiving 30Mbps as promise, and bang on, 100% and sometimes a little more.

The engineer did also have to reset my SuperHub several times as part of the expected installation routine, he didn't really know why but knew it was normal. I guess fireware updates or something, notice it doesn't have an option to do this manually in this locked down VM unit.


After reviewing my UseNet connection I found that 'something' new we happening to my download manager way beyond the remit of this forum post. S witching to FileDownloadManager I was able to achieve to full download rate which was a real world 3600KB per sec to my HDD.

So as usual, here and in my role at work as an IT consultant I find there is a problem in my approach, not the product. But how your average customer and those not so astute to join such forums as this are to get value for money from these sorts of this is a mystery.

Thanks again ppl!!!
