ColonicBoom Posted April 22, 2016 Share Posted April 22, 2016 Here's my ping plotter graph. I noticed that the R1 as first hop was showing significant packet loss on a previous test (steadily growing until 100%) so I clicked that graph to show it too. I reset everything before I started this test, turned it all off and left it all off for at least half an hour to clear RAM. PC connected to Duma by ethernet. Checked all network cables were secure at all points in the network, etc. Checked Netduma settings had bandwidth set to actual (62.8 / 2.9), congestion at 100% / 100%, Reactive, Priority reset + Shared. If you need a higher resolution image or a (nearly) 60min graph, or 10min, or 5min, I have them to. Ok Zennon, what's the damage? Link to comment Share on other sites More sharing options...
Zennon Posted April 23, 2016 Share Posted April 23, 2016 There is an issue between your hub and the duma, try new or different cable from your hub to the duma. Link to comment Share on other sites More sharing options...
ColonicBoom Posted April 23, 2016 Author Share Posted April 23, 2016 To replace that cable, I'm going to have run one down the side of the house (outside), do I need something special for this or will any old Cat5e / Cat6 do the job? It's either that or I have to use wireless because I'll have to make holes in the walls/floor otherwise. Link to comment Share on other sites More sharing options...
Zennon Posted April 23, 2016 Share Posted April 23, 2016 If it is outside you should really be using outdoor waterproof cable CB. Link to comment Share on other sites More sharing options...

ColonicBoom Posted April 23, 2016 Author Share Posted April 23, 2016 After many new cables, many restarts and much fannying about I have several new ping plotter results for dissection... Graph 1 Disconnected AP router (so nobody could connect to wifi at all), disconnected all other wired devices, leaving only my PC connected (via ethernet). Cables used were Cat5e - one of which came with Net Duma, the other is also quite new. Complete restart of Virgin hub (modem mode) and duma (5+ mins for RAM to clear).

ColonicBoom Posted April 23, 2016 Author Share Posted April 23, 2016 Graph 2 As above after another restart. Same cables. Link to comment Share on other sites More sharing options...
ColonicBoom Posted April 23, 2016 Author Share Posted April 23, 2016 Graph 3. As above but with both cables swapped out. I only ran PP very briefly because I could see it was no going to improve (800ms+). Link to comment Share on other sites More sharing options...
ColonicBoom Posted April 23, 2016 Author Share Posted April 23, 2016 Graph 4. Duma removed from network. Restarted hub for 5 mins. Ethernet direct to the Virgin hub (modem mode) - new Cat5e cable. Got these in 10 min intervals too if needed. Link to comment Share on other sites More sharing options...
ColonicBoom Posted April 23, 2016 Author Share Posted April 23, 2016 Graph 5. Exactly the same graph (same data) as above but a screen-print rather than saved from PingPlotter (because screen-print retains jitter graph). Link to comment Share on other sites More sharing options...
Zennon Posted April 23, 2016 Share Posted April 23, 2016 Wait There is jitter on the virgin hub before it hits the internet 7ms jitter this is not right I think the hub is shot or the cable from the hub to the wall. Link to comment Share on other sites More sharing options...
ColonicBoom Posted April 23, 2016 Author Share Posted April 23, 2016 Wait There is jitter on the virgin hub before it hits the internet 7ms jitter this is not right I think the hub is shot. it's wobbly right?! and spikes of up to 60ms or so using a 1 metre brand new cable. Should there even be 7ms to get from the computer to the hub on a 1 metre cable? Bagsta's show 0ms-1ms I think. Link to comment Share on other sites More sharing options...
Zennon Posted April 23, 2016 Share Posted April 23, 2016 The hub should be showing 0ms to 1ms max. Link to comment Share on other sites More sharing options...
ColonicBoom Posted April 26, 2016 Author Share Posted April 26, 2016 The hub should be showing 0ms to 1ms max. Any idea what could be causing this somewhat epic packet loss to the Netduma? I keep running tests and half the time my Netduma steadily increases in packet loss until it reaches either 65% and stays around that, or it keeps going up to 100% and then it steadily decreases back down to 0% again.

Zennon Posted April 26, 2016 Share Posted April 26, 2016 See the second hop, that is your Virgin hub when you showed me the hub on its own it was showing 7ms ping before it hit the internet, again there is an issue here. Pings travel from your duma out to the virgin hub out to its destination IP address then back to the hub then the duma the fault on the hub on the way back could be causing the packet loss on its travel home. To test use another router or go to a mates hook the duma up to his router and use ping plotter. Link to comment Share on other sites More sharing options...

Tried to book a Virgin engineer in the other day but I had to go out and was still on hold so had to ditch the call, will try again later. Link to comment Share on other sites More sharing options...

I tried to explain, ping plotter, jitter etc over the phone to someone in India probably, and tried to get them to send an engineer, with no luck, so moved to BT a few weeks ago, and so far has been very good.

I'm not going to even attempt to explain it on the phone at all, just going to tell them that my internet isn't working properly - if I kick up enough stink and they'll send an engineer out to shut me up i expect Link to comment Share on other sites More sharing options...
