Re: Can't send attachments - V poor upload problem

On the morning of Thursday August 26th between midnight and 5am:

Network resegmentation and load balancing work may result in a loss of service for a few hours in Woking, Mansfield, Warwick and the surrounding areas.

Bingo! That's most likely why my connection's gone and screwed!

Take a look at this thread...

http://www.cableforum.co.uk/board/sh...ad.php?t=16757

Guess what? On the morning of the 26th I had a modem reboot, new IP address and I noticed the UBR IP address had totally changed (it's now a 10.x.x.x address), and ever since I'm getting *major* packet loss! (all on the upstream, thus causing stalled/failed web requests and bad upstream traffic when uploading, this includes making my web server run at a crawl, though 256kbps was never speedy anyway)

I've been told this may be down to my 58 upstream power level (at that level it would be readjusting power and that causes the packet loss), but I've been living with a power level of between 56 to 58 for a year now with no problem. The problem only started when NTL "fixed" things .

So now it could be down to me to chase up NTL, get engineers out, wait in for them, etc, to sort it .



P.S. Can you guys do a quick test?

Do a traceroute to www.ntlworld.com and find the UBR IP address on the list. It will be the first or second hop (depending whether you've got a router or not), and probably a 10.x.x.x address. Then do a ping to that address to check on packet loss ('ping -t' for a continuous ping on Windows and CTRL+C to stop it, and it will tell you how much packet loss if any).

I'm interested to see if anyone getting upload problems is getting packet loss too (as it would probably explain it, and is what I'm getting).

Also are you getting problems with web pages where you sometimes have to refresh to get the page to load?

In addition to that if you can check your upstream power level too that would be great (browse to http://192.168.100.1 on most modems).
