Speed Issue - Nothing left to do but leave NTL?

Had an on going speed issue now for about 2 months. I'm on a 10mb connection and doing the speed test proves this...

1st 512K took 454 ms = 1127.8 KB/sec, approx 9293 Kbps, 9.08 Mbps
2nd 512K took 453 ms = 1130.2 KB/sec, approx 9313 Kbps, 9.09 Mbps
3rd 512K took 422 ms = 1213.3 KB/sec, approx 9998 Kbps, 9.76 Mbps
4th 512K took 437 ms = 1171.6 KB/sec, approx 9654 Kbps, 9.43 Mbps

However this is only when connecting to NTLs own Network/hosted Sites. The second I access anything away from NTL's own servers the speed drops dramatically. The adslguide speed test shows I'm connecting at about 512k. The last couple of days I've only had downloads of about 7/9k :shocked: (including from newsgroups, Apple and Microsofts sites) which is useless for me as I do a lot of work from home and Remote Desktop into multiple PCs. Trying to do it this morning and can't stay connected to a machine longer than 20 seconds.

I've phoned tech support about 6 times in the last 2 months, had 3 enginees come and look at the equipment. They've changed my modem to the new blue one, the second engineer put a 15db actuator? on the end. The 3rd one took my modem and plugged it straight into the green box down the street. All 3 have said there's nothing wrong with the equipment at all. I've tried it with Xbox360 downloads, 2 Windows XP machines, a Solaris box and a Mac Laptop and it's still the same (all 3 have been tried via the Linksys wifi 54g router and plugged straight into the modem).

I've even been contacted by Fault Management Escalation but that's dried off since they escalated it to Network Support. I emailed them 2 days ago with no reply and can't phone because their number was always with held.

Is it back down to 2mb adsl for me until my exchange is upped to 8mb or is there anything else I can do to get NTL to fix this? I'm in South Manchester (Stockport) if that helps at all.

Thanks in advance

Those speeeds are almost spot on, could you try a different Speed Test such as the one at www.adslguide.org

Thanks

Read the post again zeph ;)

Re: Speed Issue - Nothing left to do but leave NTL?

Thanks for the quick reply though :D

I've done another ADSLguide speed test this morning....

Direction Actual Speed True Speed (estimated)
Downstream 26 Kbps (3.3 KB/sec) 28 Kbps (inc. overheads)
Upstream 532 Kbps (66.5 KB/sec) 574 Kbps (inc. overheads)

3.3KB = WTF?

Here's the downstream page from my modem config...

Quote:

Downstream Lock : Locked
Downstream Channel Id : 0
Downstream Frequency : 586750000 Hz
Downstream Modulation : QAM64
Downstream Symbol Rate : 6952 Ksym/sec
Downstream Interleave Depth : taps12Increment17
Downstream Receive Power Level : -7.3 dBmV
Downstream SNR : 32.9 dB

Downstream Receive Power Level looks like it could be contributing to the problem based on the sticky in this forum.

If you believe some people, your being paranoid, a few of us know theres a real problem somewhere. ;)

Just wanted to get all the information in this thread in Black & White.

Perhaps a member of the Cable Forum team can escalate your issue *waits for Team Member to leap out of the shadows*

3.3kB/s?

Maybe if you can post a traceroute to adslguide we might be able to see something?

What would we escalate exactly ? There can't be anything wrong with his line/modem/ubr/connection as he gets perfect speed from the ntl based speed test. ntl don't control what happens beyond their network. Even that tracert looks fine.

Re: Speed Issue - Nothing left to do but leave NTL?

True enough. Do you use a Firewall?

Don't see the relevance of that, the guy's speed to the speedtest on this site is fine.

Tricky this one, traceroute to the chap's uBR is fine:

17 17 ms 17 ms 17 ms ubr02bagu.inet.ntl.com [62.253.186.33]

Re: Speed Issue - Nothing left to do but leave NTL?

Im just grasping at straws here, trying to work out what's causing the degradation of speed after it leaves NTL's network. Just considering all possibilities really.

Re: Speed Issue - Nothing left to do but leave NTL?

I'm kinda hoping someone in ntl will take an interest in this as I can't troubleshoot it nor could anyone very well that doesn't have access to the core network really.

Re: Speed Issue - Nothing left to do but leave NTL?

Well as I speak right now I am getting 5-7mb to adslguide, thats over a more than a couple of tests, but I am getting the same to robin walker, so looks like its working fine for me, much more fine then 3kb.

As I take the same route from Leeds A, if it works that way, elimination would say the problem lies between there and you.

Re: Speed Issue - Nothing left to do but leave NTL?

If you email me the modem's mac address, your current postcode, ill see what i can do..

Im only a tech tho... :dozey:
