Slow speeds

[Ignitionnet]

339MHz = second downstream frequency. In some areas where a single downstream isn't enough capacity a second downstream has been implemented. Modems range onto 331MHz (Ex-Telewest) and then may be kicked to 339MHz for load balancing purposes

Thanks for the help. I saw in this thread a frequency fix that applesauce used to kick his frequency to 339 and now hes getting 10mb. Is there a similar fix for the ambit 255 or do I need to get a tech to replace modem.

Ambits don't usually frequency drift - please post the stats from your modem.

[AppleSauce]

Not phoned up VM as of yet for a new Modem, Modem not drifted off Frequency again, does anyone know how long it normally takes for a modem to arrive? do VM send a technician to fit it or do they just post the modem over?

Thanks.

Yep heres the stats

My power level has dropped from 0.6 to 0 as well

Perhaps one of you experts can help an octogenerian out ?

I am on 20mbs with an Ambit modem that has a sticker saying 256. When installed in April Speedtest was showing between 16 & 20 mbs like clockwork until mid August when my morning check showed 18500 mbs [for the last time] and the evening 8500 kps. Since then, apart from the very odd occsasion 10 mbs but mainly 7 mbs and less. This is part one of my problem.

I haven't been idle. I have twice used 151, to India, unfortunately, because my hearing. On the first occasion I got as far as downloading "100MB_zero[2].bin" - "100MB_zero.bin" - "100MB_nonzero.bin" but was thwarted because no matter how India tried to take me on further we failed. My second try was thwarted my a terrible line. I have nothing but admiration for the very patient India technical staff.

Any ideas ? Is there any way I can get into a UK based 151 [Scotland ?} -

If you want a UK based call centre then ring 150 and speak to Customer Services and tell them your age and that you have problems with your hearing which makes speaking to a Indian call centre difficult and can they put you through to a UK centre..

You could try this speed test below.

------------------------------------------------------------------

If you are a Virgin Media customer then the best speedtest is from the link below.

Have you tried going to this link to check your speeds http://gamefiles.virginmedia.com/

click on blueyondergames>demos>then click on at least 2 large files around 400/500 mb and save them to your desktop, and then wait a couple of minutes then write down the transfer rates on the files that are running > times them by 8 and you will get a truer download speed.

Remember to stop and delete the files.



i.e : 250kbps X 8 = 2MB, 500kbps X 8 = 4MB, 1250kbps X 8 = 10MB, 2500kbps X 8 = 20MB

Hi 'whydoIneedatech'

Many thanks - I finally got a result via 150 and being transfered to an India expert who spoke with clarity. Mine wasn't a frequency fault after all it was a compatibity 'difficulty' with my Avast! anti-virus. He took me to 'safe mode', isolated avast! and I saw 19322 kbps for the first time since mid-August.

I have now uninstalled avast!; is there a way I can make this compatible with Virgin and Vista 64bit HP, or is there a good alternative virus checker ?

Best wishes .....

Those numbers look good ontheball apart from that you are showing a slightly odd downstream frequency.

That said, you are running on settings that I've not seen on anyone's signal reports before so I'm not going to pass comment as I simply don't know!

The are many different free Antivirus and Firewalls available such as the ones below.

AVG8 http://free.avg.com/download?prd=afe

The 2 below I have on my daughters Vista laptop.

Avira http://www.free-av.de/en/download/1/...antivirus.html

Comodo personal firewall http://www.personalfirewall.comodo.com/

Hi there, I've also been having some erratic speeds lately and I am also on the 10mb service which was recently upgraded in the Haringey area listed on the upgrade schedule page.

Here are the stats from my modem

Frequency 339000000 Hz Locked
Signal to Noise Ratio 38 dB
Power Level 6 dB
Channel ID 4
Frequency 41000000 Hz Ranged
Power Level 34 dBmV

The latest speed test I did was as follows:



However, this was pretty good compared to the 2 megs I was getting before with about 60-75 ping with no downloads or anything. Found it a bit strange, but it has been a recurring issue.

I just saw the last post...I also have avast running, I'll just check with it turned off. I'll buy kaspersky if it fixes the speed problems.

I forgot to mention my modem is the motorola SB5100 and I use a direct ethernet cable connection to my Buffalo WHR-G54S router.

Signals are fine, I believe Haringey is suffering a little from oversubscription - can you pop a traceroute on the thread?

[HaroldT]

Hello 'whydoIneedatech'-

I have taken your advice and installed Avira, two days ago actually, and it is behaving with decorum.

My 20 mbs Broadband is now producing between 17 & 21 mbs consistently while Avira, having completed a full virus check stands guard.

My thanks again, no further communiques will posted, unless ..........

I am also in Haringey and have had very slow and erratic d/l speeds since July. I raised a call in August about it, girded my loins for the pain that is the VM helldesk diagnosis routine and was pleasantly surprised to find the UK based guy very nice and helpful. I was able to prove the erratic and very slow d/l speeds to him in real time. He logged onto the UBR I am connected to but didn't find it overloaded so he escalated to second line.

Anyway, he found an internal VM fault reference for one of the Haringey UBR's (UBR7 I think). This UBR has TX faults and is scheduled to be replaced in November sometime. There is no fix until this is done. However, VM have given me a £27 per month discount off my XL broadband bill for the inconvenience. Well done to VM for that!

What UBR are you on?
