Nope - I'm more amused than anything else. I would be quite happy to sympathise with anyone seeing 10% speeds, a little jitter I was fine with.

I'll see what the Samknows box I forgot I had has to say before I get too indignant. I suspect the reading isn't accurate as at that speed pages should load like sludge but aren't.

in my view the modem side of the superhub is fine, I dont think its the cause of your issue. But I havent used it on the 50mbit service. A vmng300 would probably show lower latency/jitter tho but also along with bursts of bigger spikes when congestion gets too much as well as occasional bursts of packet loss. For speedtests I find the vmng300 made no difference but did affect things like web browsing speed and streaming performance.

as we have discussed it uses a different minislot size and thats about it

It seems with VM things are either fine or very bad. I do agree with you small jitter is ok and have accepted my current service as fine even with its small jitter. Its when I had large jitter I had issues with it but that was also alongside speed problems as the 2 seem to go hand in hand.

Re: Installed Finally But...

How about jitter like this Chrys? ;)

Re: Installed Finally But...

yep thats too high in my book. Sorry if you disagree but when I last had jitter that high it accompanied speed issues. The way VM run their network I dont think you would get that high jitter without speed issues.

mine below 2 mins ago taken.

Re: Installed Finally But...

also you seem to have packetloss on docsis3? going from bad to worse.

heh pip I think ignition probably got an exploding head at the moment.

Like Igni I'm finding it humourous ATM. It will be interesting to see what excuses VM give him.

This isn't ADSL, it's not going to rate adapt to try and find the most stable frequencies.

I have never had to give any of a Terayon Terajet 210 on 512k, an Ambit 100 on 1Mbit, an Ambit 120 on 3Mbit, a VM 256 on 20Mbit or a VMNG300 on 50Mbit a couple of days to stabilise.

Would appreciate it if you could put a bit of meat on those bones rather than 'it may become more stable after a couple of days.' It's a fresh install, new cable pull, everything should be fastened nice and tightly and is going by the power levels.

You asked for advice and I gave you mine.

Personally speed tests are pointless. Anytime I check I don't always get my 50mb down but it's always 5mb up. However when downloading stuff it sits around 6mbps and that's via wireless so that's all that matters really.
