Installed Finally But...
 
Well, installed, signals fine, all ok on that score....

But latency is flaky, speeds are variable.

Any thoughts you guys?

It's ok either way, still feels fairly responsive, suspect there's a bit of congestion on the upstream.

Maybe give it a day or two to settle down?

I apologise for my ignorance here, could you please run past me what needs to settle down on the device or the connection?

Software Version V5.5.2R26

System Up Time 0 days 01h:17m:54s
Network Access Allowed

I can't think what exactly will change in the next couple of days to make any difference to the performance. It's synched to the network at 4 x 55.6Mbit/s down, 1 x 10.24Mbit/s up, it is authorised to access the network and is provisioned at 53Mbit/s down, 1.75Mbit/s up, it's on the most recent version of firmware, what is there left that a day or two will change?

EDIT: Firewall features, Port Scan Detection, IP Flood Detection are disabled.

can you keep a live link going on your graph? it be interesting to see what the weekend is like but you seem on a rough port ignition :(

Stephen 06-05-2011 19:44

Re: Installed Finally But...
 
You've just had it connected, it may become more stable after a couple of days.

Cable doesn't need time to stablise. It should work out of the box.

As you sau Igni, looks like upstream congestion. You'll have a better idea tomorrow aftyer the graphs had time to populate.

Chrysalis 06-05-2011 19:48

Re: Installed Finally But...
 
yeah common isp reply/excuse for poor performing new installs "give it time". In my area friday nights are the best weekday nights as people go out, but obviously different areas will have variable patterns.

Why would it become more stable after a couple of days?

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.

That is the live graph Chrys, if it isn't updating for you you may need a CTRL-Refresh.

I'm not that bothered, I just welcome opinions as it's always easy to troubleshoot other people and just as easy to be blinkered to your own issues.

ignition curious question, given that VM is cheap and all.

If your service quallity stays as is do you find it acceptable service for yourself?

thanks will follow it. For what its worth I agree upstream congestion most likely (based on what you taught me tho) :p but for it to be serious enough to affect your downstream the latency graph looks mild.

Yes - I was merely curious given that this is my first exposure to the Pooperhub whether or not I'd missed something, or the reverse, whether I'd been so busy suspecting the Pooperhub that I'd missed something elsewhere.

As above troubleshooting other people is easy; yourself however always wise to get second opinions in my experience.

Re: Installed Finally But...
 
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.

This however I don't find acceptable.

You gotta laugh :D

Re: Installed Finally But...
 
ignition see when you the victim it looks a bit different?

I hope it either resolves itself or you get it fixed via complaints. Remember how bad mine was in jan and then the the extenct of the improvement between then and march.

Re: Installed Finally But...
 
That's pants! I take it you've checked no change in powerlevels?

Chrysalis 06-05-2011 20:14

Re: Installed Finally But...
 
just tested london and can confirm that itself is working ok. So is local VM issue I expect for you :( take a drive down to UBR tonight?
