Using that great tool pingplotter only shows PL on the first hop and all the other hops are not affected - some googling tells me failure to return ICMP TTL-expired error packets on an ICMP ping packet with an expired TTL is not a real problem, as the destination is not affected.

Anyhow - will monitor but am running a few pingplotter traces and they're currently showing green on all hops which I suspect is good.

Urgh why can't networking be easier !

EDIT: Brilliant tool pingplotter, confirms that router is ignoring IGMP packets and showing "loss" at the first hop which is actually not loss at all https://www.pingman.com/kb/article/initial-hops-100-packet-loss-6.html

So now to monitor the rest of the hops and see what happens.

I also use this tool to monitor for line issues and where possibly the problem could be.

Absolutely. Welcome, and please enjoy your stay.

Our feedback thread can also be fun when the miscreants come out to play, so pop in here every now and then too. Hopefully only for the entertainment and not frequent support. :)

You weren't getting 100% loss though. You had 0%. Then 47%. Then a few %. Then the loss appeared on various other hops. It was all quite an odd situation until that pathping revealed the true culprit.

Don't overthink it. Follow my advice from last night and temporarily change the local network setup by removing one of the routers and test again. As well as checking all cabling and trying different ports. There's also no reason for your router to be ignoring ICMP packets unless you specifically set it up like this. Nor for it to ignore them selectively. Your best bet at this stage is to physically identify the issues, as the traces we saw were quite frankly giving some nonsense data at times that I wouldn't necessarily use for diagnostics until the local network on your side is back to normal. :)

But zelda says it's true.

She also says our shaping and telkom ports need remapping.

Just gotta push out some tweaks and we're already seeing an improvement.

Thanks Shaun

IT's not the Asus - eliminated that at least.

Anyhow, running PingPlotter for a few hours now and after hop 1 there is <0.1% loss on most sites (I have crystalweb.co.za, news24, thinkbroadband.co.uk tracing) so whatever "packet loss" is happening inside my network on the first hop (Zyxel modem) is not affecting the destination latency (it's excellent) nor quality upstream on any of the terminating hops.
 
Shaun/CW - can you try explain this:

Things were fine this morning but speeds have just dropped off sharply, however my CW trial account is perfect:

Speedtest PE to CT (SAIX).

CrystalWeb Trial account: 18.55 down, 2.0 up, 36ms ping http://www.speedtest.net/my-result/4295948746

CrystalWeb capped account: 4.11 down, 1.9 up, 29ms ping http://www.speedtest.net/my-result/4295953990

How can my main CW account start acting like a dog again but the trial account is flying ?

Don't think it's my modem. All other backup accounts are fine as well this morning.
 
Netflix didn't buffer once last night! Medium to high quality on the 4meg line.

This is excellent CW. Really impressed.

Eish, this isn't the best support system, thewusman.

For actual support, always, always use the support channels, and escalate to me if need be from here. As first line support it's super inefficient.

I can investigate, but I need more data that you cannot post on a forum.

EDIT: also, as you may hear from us from time to time, speedtests make for awful diagnostics on our network. Just has to do with the fact that we don't prioritise them so they fall into a pool of traffic that's not entirely "important" overall on the network, put simply. We believe in real world performance. We could prioritise it, and then bullschit people by saying "look, speedtest is fine so the problem is on your side", but that's not the way we work.

EDIT 2: I have also taken all results and sent them off to our guys to dig into and get back to me. I'm unfortunately in various meetings and other work today so can't offer much in the way of support - but I will chase this up as and when I can. If it persists and it's account related then I'll amend that free account you have so at least on the weekend you won't have trouble and we won't need to rush a diagnosis here.

I still do believe that you need to get that local network in tip top shape. ;)
