Re: Extremely High Jitter Rate For Years.... (An ISP issue)
Sorry to hear you've been getting poor jitter. I've just checked your connection and can see that you are affected by contention fault F002780828 which is due for review 30/03/16. This will cause slow speeds and latency in peak times such as evenings and weekends.
As well as this fault I can also see that your downstream power levels are too low which will also cause poor jitter and speeds as well as the occasional drop out.
We'll have to get a technician out to adjust this and I've just sent you a private message to arrange the best time. Just click the envelope at the top of the forum to view your messages.
