1st Test https://www.speedtest.net/result/18731684530.png
2nd Test https://www.speedtest.net/result/18731689298.png

I don't know what has happen to first test much slower to 2nd test. Very strange!

Updated just seen the graph after those two test from speedtest at 4pm, it does spiked again! Not good news I am afraid. Back to square one!

In reply to a post by Taras:

is the cable anywhere near electrical cables?

thinking that the flat cable has zero twists in it and suffering from fleming's right hand rule add in a near by electrical source! I would look at the cable from the xbox to the router as well to make sure that avoiding electrical cable.

The ONT box are much further away from electricity sockets! Same with Xbox are further away from electricity socket.

What setting shall I put on download and upload please on QoS?

Try uploading something for longer.. I suspect your latency increase it is from when you comgest the upstream, which is not uncommon..

Will you be able to add upload file soon on TTB tool. I only see download only. Only asking!

Mmm... we probaby should. It's not quite a flip switch kind of thing to test it at fast speeds and to ensure it remains secure.
If you set up a web server passthrough (port forwarding) your end on a static IP I could in the mean time test it from our side a few times. I'd probably say allow 80.249.96.0/20 through.

I have swapped over back to old TP Link VX230v as connected to ONT. Going need my rest break now as I got really bad headaches and really stressed out.

Will try later tonight after snooker final has finished.

I think those boxes ask your total speed, but I'd need to check the manual. I'd start with the lowest sustained peak speed. i.e. what is your minimum speed which is really believable.. not like 500Mbps but whatever regular lowest test looks like and try that..

My TP-link has more settings.. although same two you have there..

Input the maximum upload and download bandwidth provided by your service provider.

Martin do you know the setting for FTTP QoS for 1000/115 FTTP service?

You should use the values *you see* rather than anything generic.. I suspect that the lower you set this the more it guarantees performance.. i.e. it allows non-priority traffic as long as headroom exists.. if you set it too high it won't have the headroom

(why does it sound like we're talking about the budget?)
