seems to spike during peak times which suggest congestion issue over ultisation as someone else has said virign consider it a ultisation issue if it over 90% for 7 days but it can affect from about 60% ultisation

best i can advice is to post ping test to bbc using 100 pings then using -l 1024 -l 32665 and -l 66550 esicpally during peak times do a tracert bbc.c.uk and pathping bbc.couk

and post about high pings and probally packet lost

and hopefulyl when it is the worse they might see something then raise and hopefuilyl can be fixed

Gunna keep it going for a while yet , theres a lot of issues during the day as well , at the moment its okish , it aint great but theres still spiking in games etc.

I wont bother posting on the forums it gets me no where , i will wait on this technician to come out on Tuesday and let him run his course on things , the admins on the forums never reply to me.

unless there a issue with teh power levels modem etc the tech wont do anytihng it a network capicty problem only 2nd line can raise it

Well yours looks poor but I've seen plenty worse. I'd class mine as worse and they won't do anything about that.

The packet loss around 17:30 was when I rebooted the modem on the offchance I may get a different upstream (I didn't).

I've given up on VM and am just waiting for Infinity to arrive in my area (scheduled June).

Are BTS infinity supposedly better then for things like this? Ive heard nothing but bad things from people on BT

BT ADSL has a poor reputation - at least there are lots of complaints but they are the biggest ADSL ISP in the country and ADSL in general has a lot of issues outside the control of the ISP - most ADSL complaints should in reality be addressed to <insert deity of your choice> for inconvenient/sloppy design of the physical laws of the universe.

I've seen no major complaints about the Infinity product yet but doubtless they'll come in time. It would need to be pretty dire to be worse than my cable.

Infinity - at present - has far better ping and jitter characteristics than VM cable and very little to no visible contention in most areas. Last I heard capacity utilization has barely hit double digit percentages.

Of course ADSL started out that way and still is on a couple of LLU operators but http://en.wikipedia.org/wiki/Bram_Cohen and http://en.wikipedia.org/wiki/The_Pirates_Bay put a stop to that for anyone using ISPs reselling the astronomically priced BTw IPstream bandwidth.

Still amazes me that anything uses ping (ICMP) for anything other than what it was designed for. It is a low priority traffic and when things get busy will get delayed or even dropped to allow for higher priority (TCP/UDP) traffic.

When things get really busy, ping will get lousy as that's how it should work. Now that's not to say that having bad ping and especially packet loss is acceptable especially where it degrades a service. Infinity may be better now while not many are on it, what's going to happen when that service gets really busy?

Easy - either BT will put in more capacity or it will get congested.

The difference is that congestion on Infinity will be slow to build so capacity planning should be easy because it's 1:1 back to the cab then at least a 1Gb pipe. With VM a single user can tip a local area from acceptable to dire because of the small pipes. 8 bonded downstreams will help for sure but there will probably still be oversubscribed areas.

[sparks flamewar about BT vs VM's capacity management]

In any case, I would postulate upstream on BT will always be infinitely (pardon the pun) better than VM's, due to the far lower contention - and as you say, symmetric backhaul - to the exchange. Hence how ~6mbps DSL still beats VM's 50mb cable almost by an order of magnitude when it comes to upstream stability.

Re: Can you see something wrong here? *Video*
 
Isn't it something to do with the way cable upstream works - doesn't the modem have to request a transmit time slot or something? All that faffing about is bound to be more jittery than just letting it blast (on the 1:1 back to fibre all xDSL offers).
