Hello there everyone,

These forums have been of great use to me for a long while now - however I haven't posted much (if at all), I don't think.

I hope someone would be able to help me with this painful issue I'm currently having. About a week and a half ago, I started getting random disconnects, and I'd either have to renew my IP Address or reboot my firewall in order for the connection to start working again. I would always renew to the same IP, in fact it never lost the IP, the connection just stopped working, couldn't ping anything, or visit any web pages until I forced a release and renew.

I got on to VM about this, and they sent me out a new Ambit 256 Modem. I recieved it yesterday, and thought *phew*, my problems should hopefully FINALLY be solved. However, it's started with the random disconnects again. Incidently, this started occuring after I was re-routed through what appears to be a new CMTS, and my IP changed as a result. Before the change, it was working fine.

My modem levels are as follows:

ItemStatusCommentsAcquire a Downstream Channel298750000 HzLockedConnectivity StateOKOperationalBoot StateOKOperational

Downstream Lock :

I'd be very grateful if someone could shed some light on the problem I'm having, judging by some of the info I've read, my signal levels seem OK, and others indicate that they are wrong. I thought I'd ask for some first hand advice. As I say, my problems only started occuring after what seemed to be a local upgrade in preparation for the 50meg roll-out. I live in the Guiseley/Yeadon area of Leeds. LS20.

Cheers,

Keith. (txtman21)
