Is this normal ....
 

Ok,

Ive been battling my connection for ages now, and am still seeing completely unstable pings... Someone at NTL network tech told me this was due to QoS etc on the routers.. Fair enough, so pinging the uBR isnt a good test. So i've pinged ntlworld.com on his recommendation, and am getting:

Ok so the actual responses are OK, it's not yet hit peak time... but they're all over the place? Is this all i can expect on cable, or do I have a problem like noise ingress somewhere?

Sometimes they peak into the 100ms ranges.

Cheers

Is this normal on an NTL cable connection?

Ok response times are OK, but they are completely sporadic.... I am pinging from a completely idle connection.

I even get stable pings to it from AMERICA.....

How can they tell me there's no issue with the connection, I'm on the NTL network and they definitely aren't!

Am i just sniffing large upstream congestion or something here, or do you recon there's noise ingress or something else causing an issue?

Cheers.

Re: Is this normal ....
 

I've merged your posts - no need for two separate threads on the same issue.

As for whether it's OK or not. I'll leave that to a technical bod ;)

Re: Is this normal ....
 

I didn't mean to post twice, not entirely sure what happened there....
The technical bods high up are telling me I don't have a problem and it's all to do with QoS etc, but I'm less than convinced.

I'd like to know the stability of other's ping times? .........

Feel free to paste your pings to ntlworld.com here please!!

Looks like others are in the same boat then and I dont have a case!

Guess that's what we can expect on cable then?

Re: Is this normal ....
 

No such thing as 2Mbps anymore. Its all going to be 1Mbps, 4Mbps or 10Mbps now.

Re: Is this normal ....
 

its normal for ntl I think yeah, some lucky people wont have that varation, and for me it was much much worse I had spikes up to 3 figures.

Re: Is this normal ....
 

yeah every other ISP seems to have decent latency ...

Cheers for the replies, glad It's not something affecting my connection solely then.

Re: Is this normal ....
 

How do you propose it is affecting your connection?
