I very much doubt that they changed your UBR...

Re: Signal to modem

This is possible :(

Hopefully this attenuator will sort out the problem once and for all

Re: Signal to modem

Hello there,

Sorry to hear about your troubles Rough.D
I too am in Swindon, and go via Birmingham (....brhm.cable.ntl.com) but never have any problems like you describe (oh dear, thats blown it!)

Re: Signal to modem

Hi MikeyB
Glad to hear you are not having the same probs as I am its been a right royal pain.

The engineer told me that there is a problem in the SN3 area of swindon :(
as the callout rate for modem problems has increased some 10 fold.

So far so good on a fix my signal was weak so he has boosted it from the box in the street and put in an attenuator (I think) its a filter of sorts lol
Its now a matter of waiting to see if it goes off again.

I'm pretty sure the uBR is a local thing, that your local fibre connects to, don't see how this can be changed. Other things can be changed such as web proxy DHCP server etc.

My uBR is just an Ip address, no name

Code:

Tracing route to www.ntlworld.com [62.253.162.30]

over a maximum of 30 hops:

What you are connected to is given by the name of your Ip address, ie my (munged) is

cpc1-oxfd4-3-0-custxx.oxfd.cable.ntl.com

which I'm sure an ntl tech could decode to the location

NB they should boost the signal at the cabinet then fit a Forward Pass Attenuator, so only the downstream is attenuated, not your return path.
