Re: Lost Default Gateway
 

the "easiest" thing to do is to try your internet connection on another pc, just to completely determine (unless it's power issue?) that it's an ntl problem or not.

Re: Lost Default Gateway
 

I don't think it's my machine - I've seen it at a friends house a while ago but never found out what the resolution was (they just said it's not happening any more). The only common thing is they they were on NTL BB as well. It could be something specific to Belfast though.

when it does go wrong does the D/S light on your CM flash now and then, while your U/S light does nothing at all?
this is what happens for me when mine crashes (which i've worked out how to make it do it whenever i want now using about 100 connections and a lot of uploading on each one to another server on the internet i own).
(only fix is to power-cycle the modem, ipconfig/renew will not fix it, but the pc does keep the wan ip address, it just doesn't actually work)

Re: Lost Default Gateway
 

Yep, power cycling the modem is the only solution (reboot of the pc does nothing). That's my point though. Why do I have to reboot the modem to stay always on? It might as well be a super duper fast as hell dial up modem that disconnects after two hours idle time.
Can I total up the time I've been disconnected and ask NTL for a rebate?

Re: Lost Default Gateway
 

in order to try and claim cash back from NTL, i imagine you'd have to prove that it is their fault, and they'd have to agree to that.
you could try and get a replacement cable modem if tech support will let you.

cichlid,

I have been dealing with this problem for a good part of the last month... tried everything I could think of.

I think I finally traced it back to bittorrent, I closed down my client and my connection remained stable. I tried a diff client and it starts all over again. Haven't used BT all week and haven't had any problems. I connected to it briefly the other day and sure enough I lost my connection shortley thereafter (same semaphore timeout error).

Anyways if your running a BT client that could be it, I still haven't figured out exactly why thats causing the problem, but atleast I have found the root.

What ISP are you using? I am on oceanic rr.

Re: Lost Default Gateway
 

Bittorrent is a red herring. I've seen it on a machine with a completely different set up. I'm beginning to think that the NTL branded modems that they supply are k-wrap / insufficient / unstable. It has happened when using bittorrent but has also happened at other times. Must go and check out the specs of these modems (if I can) to see exactly what they are capable of.

Re: Lost Default Gateway
 

I have been having the same problem for ten days now - it started when i was on bear share i have all kinds of problems since . I contacted telewest who told me it was basically my fault.
i have got really fed up of constantly pulling the power lead out of the webstar modem .
I had a look on the http://192.168.100.1
it gave me some very interesting information from my modems log
i had BPI flash : The mfg CA Cert not found
DHCP warning - non critical field invalid in response
msn messenger tells me my default gateway is offline
can any one help - telewest are insisting it is me

Re: Lost Default Gateway
 

Does http://192.168.100.1 give the upstream and downstream power levels, and SNR etc, if so can you post them.

Re: Lost Default Gateway
 

Do you have a firewall at all, also have you double checked your settings for Internet Explorer connections.
BTW this thread is nearly a year old ;) Welcome to the forum lol

Re: Lost Default Gateway
