Jitter on the line

[#1]

Hello,

I am experiencing a lot of latency jitter on my line. Average ping is about 30, but jitter every few seconds at +300ms, making anything real-time (say gaming) unusable.

Things I have tried that didn't help:

• Disconnect everything (20kB/s) on the line, so fairly quiet. No wireless enabled, single device connected by 1m of cat5.
• Different router with QoS settings.

I've also noticed that on my LAN side of the network there is no jitter, even under load (0.8ms deviation on average). Only appears to manifest once a connection leaves my home network. I also got out the 'ole wireshark to watch it, and i've noticed its entirely on my download packets, rather than my upload which remains jitterless. This is confirmed by some games that have telemetry built in such as CounterStrike which have latency/jitter graphs.

I've talked to support but they say theres not much to be done from their end.

Am I doomed to experience jitter? Does anyone have any thoughts as to what I could try next?

Any help would be much appreciated.

What service are you on? - latency is often worse with ADSL than with FTTC (or FTTP) simply due to the lower speed.

Has it changed recently, or has it always been bad?

Unfortunately latency - like upload speed - is something Plusnet don't offer any guarantee for, so it needs the right member of staff to get latency issues investigated.

Hello,
It's fibre to the cabinet is my understanding.

Unsure if its a new thing, only recently started playing games again.

Yeah, I fear you're right, which means I'm not sure it's solvable. Hopefully someone else has a solution, but we'll see. Thanks for your response though.
