Interpretation of results


[link to this post]
 
I have been having quality of service problems for over a month now. I have tried three different modem/routers - Billion, Draytec and Fritzbox, with 5 different devices, pc, laptop, phone, ipad and smart tv and the same problem persists, continual dropouts. BT have tested line and it appears to be synching well they have also apparently moved to a different VLAN but I am still getting [censored] service. Zen my ISP have had me disconnect all phones and plug directly into test socket but the dropouts still occur.
The link below is monitor of last night. No internet use between 10:30pm and 8:30am. Dropouts seem to coincide with that yellow latency spikes.
Any suggestions of the root cause of the problem please.

There are no almost certainly no disconnections showing there. A disconnect will normally cause a 1 or 2 width red line right to the bottom, though a very rapid reconnection could be a single line to about three-quarters of the way to the bottom.

Is this ADSL2+ or FTTC?

Given the huge number of packages lost all the time, I expect if you are using wifi to connect to the router the wireless could frequently fall over. Do you get frequent drops when connected wired to the router, and is it a combo modem/router? I believe it is but it is wise to check with you, as if you have modem feeding the router we are possibly looking at more possible causes.

Thank you for prompt response.
It is FTTC nominal 40/10 service but in practice more like 33/4.

All used are combined Modem/Router , Billion 8900-AX, Draytek 2760n and FritzBox 3490 (on loan from Zen).

I do use wifi to connect to the router but the main use is from pc which is Ethernet to LAN port on router..

The modem logs indicate dropouts as the short extract below:-

As you have seen from the graph of my original post the packet losses continued throughout the night even though the pc was turned off and none of the wifi devices were in use..

As you will appreciate it is impossible to use anything like iplayer or Netflix..

Your package loss red, may not be real, the Fritzbox routers have a habit of showing lots of packet loss when that is not the case i.e. it decides to not respond to the ping box at times.

If this was real packet loss would usually expext to see the yellow/blue and green areas showing a lot more variation

If the Fritzbox dropping the sync in addition to the PPP session being dropped?

It may be that PPP echo is being missed and router dropping connection to reconnect things.

OK Thanks for this suggestion.

I will replace the Fritz with my own Billion and see how that goes tonight. Was only using the Fritz to rule in/out hardware problems, but it seems device independent.as Zen indicated that the recorded 500 dropouts over the weekend before last.

Will see how the Bipac pans out.

I did change back to my Billion 8900AX, and that together with BT migrating the SVLAN has improved matters greatly.

The router logs are showing no disconnects and the BQM graph, as below, is also greatly improved, and I did manage to watch about 30 mins of iplayer this evening without constant buffering.

I will continue to monitor performance.

That's a lot better, but really there shouldn't be any red at all. Considerable yellow and even high blue are expected when doing considerable streaming smile.

See how things go.

My optimism was premature.

Zen - BiPAC - 6/12/18

I will close Ethernet connection to router and disable wifi and see what transpires overnight.
