High latency and packet loss in south Manchester.

Hi on the 200Mb service in south Manchester, really struggling with poor ping times/jitter (esp Fortnite, but also Call of Duty and others).

Is there anything I can do? I think it's congestion on the service rather than any setup. PC is wired connection (cat6) to router -> cable modem mode.

Also lucky to get much above 140Mbps (except occasional bursts or at 3am which shows there is no config issue). 

Thinkbroadband graph shows lots of jitter and packet loss.

Re: High latency and packet loss in south Manchester.

Looks to me like a combination of over-utilisation, and a noisy connection.  If it was "only" over-utilisation then your BQM would be spike free from about half past midnight to around 8 am.  Whilst noise issues can (usually) be fixed, VM's record on fixing over-utilisation is very poor, and although there's probably a fault reference and a fix date, there's no way of knowing if they really plan to carry out works to address the issue.

If you're out of a fixed term contract you may want to investigate alternative ISP options.  If you are in contract (and want to leave) then carry out a series of speed tests at peak times and see if you can get the evidence to invoke the minimum speed guarantee.
