Ping Fluctuations Since Work Done By OpenReach


[link to this post]
 
Hi, I am hoping this is the right place for this and I will try and get to explain this as best I can, I really hope someone can help me smile

So I have VDSL2 on a 71/20 line which my DSL stats on the modem shows, and my internet has been perfect for at least 3 years with my ISP. A month ago I reported to my ISP that my provided router/modm was soft crashing every hour and after 5 seconds everything was good again, so I wanted a replacement. Instead of this, they did a line check and apparently found a fault on my line (when I told them it was perfect, thats not what was wrong). So a few days later my ISP got back to me and said an Open Reach engineer did some work on my line at the cabinet and since then my pings have been unstable, and fluctuate/change every second. This is a snapshot of what I get at any time of day to bbc.co.uk

I know before anyone says, my pings are low and I do get the max speed from my line, 0% packet loss. That is all great, but my pings were never like this before, and all it causes it constant Latency Variation issues in gaming, where my gaming ping is higher than it used to be and changes all the time, like the results shown above. As an example on Rocket League, my pings will be 30, 37, 27, 34, 39, 25, 28 etc etc every second and all I experience is lag and rubber banding. Before Openreach did anything, my pings used to be a solid 10ms on a ping test, and within games like Rocket League my pings would be a solid 18 and never changed.

I am at a battle with my ISP to get them to fix this, and since then they have told me an OpenReach engineer has checked the line again and found nothing wrong with it, so do I keep challenging this? i am quite tech savvy but having to self learn these past few weeks about DSL and other stuff.

I dont know if the following line info is useful or not, but does anything here look wrong? The cabinet is around 20 meters from my house.
SNR Margin down 5.9 dB
SNR Margin up 10.1 dB
Line Attenuation down 2.9 dB
Line Attenuation up 5.5 dB
Power down 13.5dbm
Power Up -10.5dbm

I have purchased a new TP Link TD-W9970 and its the same issue as my Asus DSL N17U that my ISP gave me, so its not a hardware issue. Like I say, the problem literally started since something was done on my line/cabinet. Running a ping test to my modem/router it is a solid 1ms at all times.

I have turned off wifi and just ran my pc via ethernet to the modem and its still there, and I am not saturating my connection as during tests, nothing is downloading. If anyone can help shed some light on this please I's be extremely grateful. If further info such as tracerts would help, im happy to share some.

Thanks again in advance.
