I have checked your local chassis (router) and can see that there are periods of high load which will cause your speed to slow. If this load continues to increase this will be passed to our network teams to look at ways to alleviate some of the load. We are sorry for any inconvenience this may be causing you.

Tazz i used to live in a high student area and i went through over 3 years of it, every 7-9 months network would become oversubscribed and they would give a date of 2 months which would turn out to be more like 6 months for upgrades.

Had to reload Superhub today after it forgot how to forward TCP packets.

Checked service status and, while it obviously doesn't apply to me, my account number flagged this up:

Hugely confidence building when you think I've had the service for less than a week and this is the second total CATV outage there has been nearby.

the network up your end looks amazing

Re: Installed Finally But...
 
VM aren't rebuilding it for nothing, Telewest should have done it years ago.

I wonder if the packet loss is being caused by the Superhub or the packet loss is causing the Superhub to throw a wobbly. Firmly inclined to blame the Superhub as loss stopped when reloaded.

the network is probably causing a lot of errors to be sent to you, and the superhub is trying to correct codewords, bearing in mind the performance of the superhub in general, then give it all those errors, its a recipe for disaster!

Looks like I owe the Superhub an apology. While the issue seemed to clear up after the reboot it looks like it was a coincidence and it's the network, specifically upstream.

These were done simultaneously:

Ping statistics for 194.168.4.100:
Packets: Sent = 100, Received = 48, Lost = 52 (52% loss),
Approximate round trip times in milli-seconds:
Minimum = 9ms, Maximum = 66ms, Average = 15ms

Ping statistics for 192.168.0.1:
Packets: Sent = 100, Received = 100, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 1ms, Maximum = 221ms, Average = 6ms

This packet loss has been replicated using the Superhub's own ping utility.

ping of 221ms to the hub????? wtf? anything more than 1 is suspicious in my opinion

to the dns seerver craig ;)

I had ignition's pain before the vmng300, when you have a device so broken it becomes too easy to blame it for 'any' problem.

ahh yeah I see now he did 2 lots of pings, what the ....

Ping statistics for 192.168.100.1:
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 0ms, Maximum = 1ms, Average = 0ms

vmng300 seems ok.

I don't really care about latency to the Superhub, I've had routers that can't be bothered to respond to pings unless they feel like it, doesn't worry me. It was purely there to prove that the packet loss wasn't local.

It's gone now and stuff is working.

craigj2k12 12-05-2011 20:54

Re: Installed Finally But...
 
iv never had a ping to the modem or router, my old belkin, and even the superhub has response times never more than 1 or 2ms

looks like you have a very dodgy superhub, you should put it through its paces when the network problem is sorted

I have seen it when the router isnt the endpoint, eg. my speedtouch will have around 99ms on its hop in a tracert but when I pinged it direct as an endpoint was sub 1ms.

This was done over wifi - not bothered by latency purely interested in packet loss :)

Not peak time for another couple of hours here yet, sweet. Will have a couple of rum and cokes and see if that balances out the jitter ;)

VoIP is usable but unpleasant, occasional garble as jitter goes high and requires a temporary buffer. It's not impossible to use but tricky to conduct a business grade conversation on.

This is something of a new experience for me, I've never had this problem using IP Phone at home before, that said previously I used it on O2 DSL.

Just glad it's sunny out and plenty of people at the pub!

You couldn't make it up could you, the V+ box locked up and now sits there with a couple of lights on on the front doing nothing, a power cycle made no difference.

Quality.

Re: Installed Finally But...
 
ignition no vmng300 yet? usually they send out fast.

Ignitionnet 14-05-2011 18:48

Re: Installed Finally But...
 
I haven't asked for one. Given the Superhub isn't reloading I'll leave them alone rather than bothering them for one. The lady there has been more than helpful enough.
