Re: Speed starts normal then shoots down by 20mbps


[re: timl] [link to this post]
 
It's coming up to a week now and Zen still haven't told me what the problem is or what I can do to resolve the issue. I'm seriously thinking about changing to a different ISP.

And so it transpires that Zen support have said they believe my equipment is causing this issue and they haven't done anything to get it sorted out. I even tried making a complaint, but they ignored that.

I can't believe I've been paying so much money for this complete lack of service.

They sent me a "trial" router .. made no difference.

Can you try a resync tonight see what happens, wondering if they are priortising a new router at all ?

Do a tracert to echo.zen.co.uk (just so we both know going to same server).

Well I guess they're trying... smile I was quite amused when Zen told me that on my FTTC circuit (which syncs at 63Mb) was quite within normal service parameters with a speedtest (from Zens servers of 31Mb/s!

Here's the traceroute to echo.zen.co.uk. I'll try resyncing again but I did it on Sunday, left it off for an hour then again on Monday morning for 4 hours (though to be honest that was cabinet wide) and did 4 ppp resyncs...

Well mine shafted again .. resynced itself at 2AM and is now at half speed.

I notice the first hop has changed ... starting to feel very much like routing to me.

I'd agree and very interestingly Zen have just altered the routing of my link. It's very different than the one I was getting before.

At least initially the link is back to its former performance.

Haven't seen that second hop before on Zen. New network equipment maybe?

Is everyone still on track .. mine has dropped back to 30mb ceiling.

I have requested the ability to leave without penalty as per their charter ... 2 months of this and the latest email asked me to use the "master socket" .... sigh.
