New modem, bandwidth upgrade, horrible speed drop!
 

Hi all,

First post here, so forgive my newbiness.

I've just upgraded to 10mb. NTL replaced my trusty old CMX modem with a ntl:250 because the CMX was not able to support 10mb.

They installed it today and after the engineer had left I ran the same speed check that I had run earlier this morning (before the modem swap). The check was from adslguide.org.

Disappointingly, whereas before I was getting speed reports of up to 6mbps down and almost 500kbps up, I now get 0.9mbps down and 0.1 up. I understand that these tests are flaky at best but I was certainly not expecting a drop!

Nothing else has changed on my setup other than the modem. Can anyone offer any suggestions as to what's going on?

Also, another thread in the forum talks about a CF speed test and mentions a link at the top of the page - all I can see is links to google ads about speed tests. Is there a specific CF test and if so, where can I find it?

Thanks for any help.

Thanks guys! I cannot believe I missed the link - I searched for a good five minutes!

Anyway, the sad news is:

1st 512K took 5172 ms = 99 KB/sec, approx 816 Kbps, 0.8 Mbps
2nd 512K took 5516 ms = 92.8 KB/sec, approx 765 Kbps, 0.75 Mbps
3rd 512K took 4484 ms = 114.2 KB/sec, approx 941 Kbps, 0.92 Mbps
4th 512K took 3875 ms = 132.1 KB/sec, approx 1089 Kbps, 1.06 Mbps

Overall Average Speed = approx 903 Kbps, 0.88 Mbps

I'm guessing this is indicative of a problem that needs to be reported to NTL. Meanwhile, does anyone have any thoughts about why it should drop so suddenly and so much?

Cheers.

UPDATE:

I found a tier level check at NTL which, to my horror, told me I was on the 1mb service! AAARRRGGGHHHH!!!

A call to Customer Services (I was talking to a human being within 30 seconds) had the problem rectified within about three minutes - during which time I also upgraded my package to include the unlimited calling plan.

New test results:

1st 512K took 547 ms = 936 KB/sec, approx 7713 Kbps, 7.53 Mbps
2nd 512K took 500 ms = 1024 KB/sec, approx 8438 Kbps, 8.24 Mbps
3rd 512K took 468 ms = 1094 KB/sec, approx 9015 Kbps, 8.8 Mbps4th 512K took 907 ms = 564.5 KB/sec, approx 4651 Kbps, 4.54 Mbps

Overall Average Speed = approx 7454 Kbps, 7.28 Mbps

I am a) a happy bunny and b) my faith in NTL has been restored (for now!!). Because they dealt with it so quickly I will overlook the fact that I had to call about it in the first place.

did they charge you for swapping the modem out? i still got an old cmx and see about 7meg on so am tempted to get ntl to replace it if its free

Hi,

No they didn't charge me but that doesn't seem to be the norm. When I first upgraded to 10meg I asked their advice about replacing the modem. I was told that I could buy one from ntl and when I asked if I could get one cheaper from eBay they said that was fine. Of course when I then called to get the new mac address registered I was told that this was wrong advice and I could only use an ntl supplied modem. A quick call to customer services with a bit of a sob story and they agreed to replace it free.
