Constant ping spikes/packet loss

Starting around a week ago broadband has been suffering from constant latency issues and packet loss, download speeds have also been tanking to single digits multiple times on speed test.

Hoping somebody that knows more than me can help me figure it what is causing these problems, thanks.

Re: Constant ping spikes/packet loss

Basically you have a really bad conectivty issue. In order, your downstream power levels are way too low on all of the channels, similarly the S/N ratio values are too low on all but on of the channels and is boarderline on that one. the upstream, power levels are just about in spec but close to the upper limit.

Other than just checking that you have no loose connections anywhere on the back of the Hub, on the wall sockets and in the box on the outside of your house where the cable comes up, there's little more you can do. You will need an engineer visit to check the levels between yourself and the street cabinet. Either wait until a member of the team get to this thread and offer to get in contact with you directly and arrange something or call CS and (politely) demand an engineer visit - don't be fobbed off with any 'we'll send a signal to the box' or 'change wifi channels', in fact don't mention wifi at all - there's nothing that can be done remotely.

Re: Constant ping spikes/packet loss

Checked the connections and everything seems secure but still seeing the same downstream levels, guess I will have to wait for an engineer to fix it, thanks for the reply.

Also have had a quality monitor running for around a day now which is showing clear issues
