No improvement this evening!

I can't even get the speedtest to complete - it takes forever with sub-10Mbps speeds and then I get an error

Latency is all over the place tonight though http://www.thinkbroadband.com/ping/share/efb4eb9bc40... (and I'm not sure what happened at 12pm)

We seem to have similar spikes in latency from 8 to 10pm though

Report all the problems ( you most likely done it) to zen they may acknowledge that there is a fault somewhere

Zen have now changed me over to a new Gateway here is a graph of the new gateway.

Speedtest result is looking better: Link.

However, it may be too early in the evening to be sure so will re-do the tests at 8pm, 8:30pm & 9pm.

Will also be interesting to see if my Thinkbroadband Quality graph shows less spiking between 8pm and 10pm,

EDIT: Some more interesting info, so the reason Zen could not move me from the older gateway was due to me being on IPv6. However, it turned out that the R7000 Netgear IPv6 does not work with Zen. Router gets an IPv6 address but does not get IPs for clients connected to it. I knew about this and simply had IPv6 off in my router as there was no need to have it on if it did not work and thought nothing more of it.

So this according to Zen could have been the reason the Gateway swap would not take effect, whether being on a IPv6 Gateway but not actually using IPv6 was what was causing some of the problems can not be confirmed.

to me it's not to the annoying yet, I started to experience slowness at random times. only for a short while though. then picks up speed. when it slow down it. it's really slow. I thought it was my exchange

Getting some seriously poor speed test speeds right now.

Another thing has also caught my attention. Since moving to a statically routed IPv6 setup, Zen now assign me the same static IPv6 address on the PPP interface from the delegated /64 prefix. So I thought I would setup a BQM to monitor it, along with one of my chosen static IPs on the /48 prefix.

The BQM graphs show that, roughly speaking, the latency of ping responses from the single /64 prefix address are twice that of the IPv6 address from the /48 prefix, and the standard IPv4 address. Not that this is an issue, I'm just curious why there would be this discrepancy. I guess it might be router/OS related (CentOS).

I'm having a stranger issue - speedtests display one fairly poor result (let's say 25Mbit/s single threaded), but downloading files through a web browser give even poorer results (1Mbyte/sec = so 8ish Mbit/s) regardless of origin server.

Multithreaded, once again, is absolutely fine - 73Mbps+ as usual

Incredibly infuriating. AFAIK it's not a problem with my network or computer or browser, because do it again at 3am and you'll get 8Mbyte/sec easy

Exactly the same as us, Changed gateway and its still the same.

Very annoying.

Been getting very slow downloads for some time - about 8Mbps on an 80Mbps fibre connection. Strangely when using a vpn speed increased to about 20Mbps. Used to get 70-75Mbps regularly

I knew about this thread and just thought "Me too".

Finally got round to phoning Tech Support yesterday.

Excellent service - guy (forget his name) talked me through a number of tests and eventually he thought it was the router.

Got hold of another and hey presto - speed back to 74Mbps bursting to 77.

Ah well!

graph looks a complete mess, not just the latency but is fair bit of packet loss also.
